ANALYSIS

WILL A NEW PM SHAKE UP JAPAN’S ENERGY POLICY?

  • The ruling LDP selected Takaichi Sanae as its leader, making her the likely candidate to become the nation’s first female PM.
  • Given energy’s central role in Japan’s digital modernization, and Takaichi’s own keen interest in the topic, we expect energy policy to be a major focus. Takaichi also wants the energy sector to reflect national security and industrial concerns.

BESS MARKET BOOMING AS MORE NON-ENERGY FIRMS ENTER THE SECTOR

  • With the rapid expansion of renewable energy, battery storage is moving from a niche supportive technology to one of its central drivers.
  • Yet Japan’s grid infrastructure remains ill-prepared. Curtailments of solar power are common, and large-scale transmission upgrades are not expected until the 2040s. How will the BESS sector fare in the circumstances?

Japan postpones 4th round of fixed-bottom offshore wind auction

(Government statement, October 1)

  • The govt postponed the fourth round of fixed-bottom offshore wind power tenders (FY2025). The bidding process was set to begin on Oct 14.
  • The decision follows a request from the national govt, which is reviewing the reasons behind the withdrawal of operators from three Round 1 offshore wind sites and examining how to strengthen the business environment to ensure future power generation investments are completed.
  • The review is expected to be concluded by the end of the year. A new schedule for the auction will be announced once it is finalized.
  • TAKEAWAY: Given the flux around the offshore wind sector, it was always inevitable that METI would delay the next round bidding. Without clarity around the status of projects from previous rounds – which are facing heavy commercial and other pressures – bidding appetite for R4 was expected to be weak. Still, officials have stressed that they remain committed to helping the offshore wind industry get on its feet in Japan and will move expeditiously to resolve current issues. So, the R4 delay is not necessarily a negative development. It’s a pause to ensure that the sector rules are on the right track before auctions resume.

Survey shows over 80% of business leaders view wind targets as unrealistic

(Nikkei, October 8)

  • A recent Nikkei survey of 100 CEOs found that over 80% of business leaders view the govt’s wind power targets as difficult to achieve, citing soaring material and labor costs that make projects unprofitable.
  • CONTEXT: Japan aims to raise wind power’s share of electricity from 1% to 4–8% by 2040. But the exit of a Mitsubishi-led group from offshore wind projects in Chiba and Akita has cast doubts on the sector’s viability.

In response, the govt is revising its system to allow cost pass-through and longer project terms, but transmission grid connections and feasibility remain a concern.

  • Amid rising electricity demand from AI and data centers, nuclear energy is gaining renewed support, with 87% of executives backing new or next-gen reactors, a sharp rise from the previous year.
  • Despite that, nearly 40% still support expanding offshore wind, emphasizing the need for a balanced energy mix. Executives also stressed that large-scale renewable projects require stronger national leadership, funding, and public acceptance.

Coexistence tax approved for solar and wind farms

(Government statement, October 6)

  • The Ministry of Internal Affairs and Communications approved Aomori Pref’s proposal for a “coexistence tax” on solar and wind facilities with a production capacity exceeding 2 MW and 0.5 MW, respectively.
  • The tax applies as follows:
    • Protected / Conservation area (solar): ¥410/ kW
    • Protected / Conservation area (wind): ¥1,990/ kW
    • Adjustment area (solar): ¥110/ kW
    • Adjustment area (wind): ¥300/ kW
  • The tax will be reviewed five years after implementation.
  • CONTEXT: “Protected / conservation area” is a location where renewable energy facility construction is strongly restricted due to biodiversity protection (national parks, natural reserves, etc); and a special construction permit from METI or the MoE is required. An “adjustment area” is where renewable energy facility building is less restricted, but still requires a special construction permit from the prefecture.

Pasco introduces Japan’s first floating lidar for offshore wind

(Company statement, October 8)

  • Pasco, a geospatial services provider, introduced Japan’s first floating observation system for monitoring both wind conditions and fish schools. In September, the firm began surveys off the coast of Wajima City, Ishikawa Pref.
  • The new floating lidar system combines wind and ocean condition measurement with fish monitoring in a single buoybased platform.
  • The collected data will help energy developers make decisions and support consensus-building with fisheries and other local stakeholders.
  • TAKEAWAY: For offshore wind projects more than 10 km from the coast, wind condition surveys using floating lidar are essential to assess project feasibility. Traditionally, wind, ocean, and fish surveys required separate equipment. By integrating these functions into one system, Pasco’s approach improves survey efficiency and could help reduce costs.

TEPCO to provide ¥100 billion to Niigata Pref for Kashiwazaki-Kariwa restart

(Asahi Shimbun, Oct 8)

  • TEPCO will provide about ¥100 billion to Niigata Pref as a regional contribution measure, aiming to gain support for restarting Kashiwazaki-Kariwa NPP.
  • The money will go into a prefectural fund for local development and will come from profits generated by the plant once it is operational. TEPCO will discuss payment details and usage with the prefecture.
  • CONTEXT: Restarting the NPP is crucial for TEPCO’s financial recovery, as it still faces onerous costs from the Fukushima accident cleanup and compensation. Yet, local consent is essential, and the governor’s approval is the final hurdle.
  • SIDE DEVELOPMENT:
  • Mayor comments on recent survey for Kashiwazaki Kariwa’s restart
  • (Nikkei, October 7)
    • Kashiwazaki’s mayor said TEPCO hasn’t dispelled public “anxiety and distrust.” On Oct 16, TEPCO’s president will explain safety measures to the regional assembly.
    • The mayor’s words follow a survey showing 69% of residents worry about TEPCO operating the plant.
    • The mayor wants TEPCO to clarify “determination and specific measures” and criticized the govt’s definition of “local consent” for a restart as insufficient.
    • He said more discussion is needed before the city agrees to Tokyo’s request to restart.
  • TAKEAWAY: As we have noted in the past, it would likely have been easier for the restart to occur if the entity in charge was not called TEPCO and linked to the original Fukushima disaster. No matter how much the utility promises in local funds or claims that it is ready technically, local stakeholders are clearly divided. Arguably, TEPCO would benefit from being allied with another, more ‘respectable’ entity to run this NPP. For now, we expect these local procedures to drag well into 2026.

(Nikkei, October 11)

  • KEPCO said the completion of the dry storage for spent nuclear fuel at its Takahama NPP is now slated for 2028, a delay of one year.
  • The delay is due to a slow safety review of the Japan Nuclear Fuel reprocessing plant under construction in Rokkasho.
  • CONTEXT: KEPCO planned to start work this year and complete it in 2027, but both deadlines are now pushed three years forward. The facility transfers spent fuel from the plant’s storage pools to support smoother fuel shipments.

Japan reassures Australia over gas exports

(Financial Review, October 8)

  • Japan’s ambassador, Suzuki Kazuhiro, reassured Australians that Japan’s resale of LNG is minimal. He said it’s not a major cause of energy shortages on Australia’s east coast, adding that when such resales do occur, they help decarbonize coal-reliant economies in SE Asia.
  • The ambassador welcomed Australia’s extension of the North West Shelf gas project, a positive signal to Japanese investors about Australia’s long-term commitment to gas.
  • Australian manufacturers, led by Bluescope Steel, are calling for state intervention in the gas market. The goal is to secure lower prices for domestic users.
  • Bluescope’s CEO argued for redirecting uncontracted gas to the local market and creating a gas reserve.
  • TAKEAWAY: Australia is Japan’s largest source of LNG, covering almost 40% of its total imports in FY2024. While Australia is relatively close to Japan, without shipping chokepoints, and is politically friendly, importing LNG from Australia has downsides. Analysts say Australia’s longer-term capacity to stay an LNG exporter is doubtful. For a while, Eastern Australia ceased exports, experiencing energy shortages because of aging gas fields and limited pipeline capacity. Moreover, the local industry faces increasing costs and more stringent regulations. In the meantime, Japanese companies have intensified LNG trading, a tendency that has alarmed some Australians, who see it as profiteering. Hence, Suzuki decided to make the reassurance.

ANRE moves forward in designing Generation Benchmark for power sector

(Government statement, October 10)

  • ANRE is designing a “Generation Benchmark” for the power sector, a key part of its emissions trading scheme (GX-ETS). This will set a standard for CO2 emissions intensity (t-CO2 per kWh) for power generators.
  • The initial focus is on fossil-fuel power plants. The plan is to start with fuel-specific benchmarks (coal, LNG, oil), followed by a transition to a single benchmark for all thermal power by 2033.
  • There is debate on whether to group power plants by size and efficiency for fairer comparison. Cogeneration (heat and power) will be part of the scope. But only the emissions associated with electricity generation will fall under this benchmark.
  • Power from non-fossil fuels like hydrogen, ammonia, and biomass co-fired with fossil fuels will fall under separate activity data.
  • The final WG meeting for this fiscal year will present specific benchmark levels. In autumn, it will submit the proposal to a higher-level subcommittee to be finalized.
  • TAKEAWAY: Japan is accelerating the GX-ETS design, aiming for an outline by year-end. A central design choice is the initial use of fuel-specific benchmarks. This is to prevent undue burden on coal plants and ensure grid stability, while acknowledging their higher emissions. Still, the competitive advantages under this initial system could well become entrenched since the plan entails a transition from the fuel-specific benchmarks to a single average for all thermal power.

METI explains rules and regulations for CCS storage projects

(Government statement, October 8)

  • METI set up a new working group for regulations in four critical areas in carbon capture and storage: 1) Monitoring leak prevention; 2) Site closure and project termination; 3) Financial security; and 4) Business Rules.
  • Under the framework, the private operator injects CO2, conducts monitoring, and other measures. After injection stops, the operator must submit a Site Closure Plan for ministerial approval. It also has to plug wells, remove surface facilities, and ensure well integrity to prevent leakage.
  • After closure work, there’s a post-closure monitoring period. Upon proving the site is stable, the operator can apply for project termination. Once approved, responsibility for long-term monitoring and management transfers to JOGMEC.
  • To transfer the site responsibility to JOGMEC, an operator must prove long-term stability – that CO2 is stored according to standards based on monitoring data and predictive models.
  • Operators must secure funds during operation to cover future closure costs.

Likely Next PM Takaichi’s Energy Ambitions Collide with Political Uncertainty

On October 4, Japan’s ruling Liberal Democratic Party (LDP) selected 64-year old Takaichi Sanae as its leader, making her the likely candidate to become the nation’s first female prime minister. This marks a historic moment for a country yet to promote women to the highest levels of political power.

 

Gender issues aside, what does this mean for the energy sector? Given energy’s central role in Japan’s digital modernization, and Takaichi’s own keen interest in the topic, we expect energy policy to be a major focus under her anticipated premiership. She has often spoken about the need for the energy sector to reflect national security and industrial concerns.

 

In practice, Takaichi is likely to deliver nuanced support for the renewables sector – one that places emphasis on home-grown tech and regional integration. She’s also likely to prove a staunch nuclear power backer, contrasting with the ambivalence of outgoing PM Ishiba. That pro-nuclear stance is further assured via Takaichi’s close ties to veteran power brokers such as Aso Taro, but will surely bump against regional resistance to reactor restarts.

 

How much of Takaichi’s grand energy vision can filter into reality is unclear. The LDP holds only a minority of seats in the Diet, and Takaichi will need to rely on other parties’ support to enact policies, especially after coalition partner Komeito announced its exit from the 26-year arrangement. This also makes Takaichi, should she become PM, even more reliant on support from elders like Aso, who helped her secure the leadership win.

 

Overall, a Takaichi government is unlikely to result in significant departures from current energy policy.

Past stances on energy

Takaichi’s past stance on energy serves as an indicator for future policies. As a former

Minister of Internal Affairs and Communications, and Minister of State for Science and Technology Policy, Takaichi consistently advocated for a shift toward decentralized, resilient energy systems to address vulnerability to natural disasters and demographic decline.

 

At a conference a decade ago, during a dialogue with Professor Kashiwagi Takao of the Tokyo Institute of Technology, Takaichi spoke of the potential of distributed energy systems to realize the “Local Abenomics” agenda – a localized iteration of former Prime Minister Abe Shinzo’s economic revitalization program. This is based on the idea that self-sufficient energy infrastructures can spur regional economies by fostering resilience against major shocks.

 

Takaichi’s historical advocacy for energy efficiency infuses this framework with a nationalist inflection, interpreted here as a strategic emphasis on bolstering energy facilities’ robustness against extreme weather and resource inefficiencies. Such resilience-oriented nationalism is likely to manifest itself as support for revitalizing aging hydroelectric facilities, advancing next-generation geothermal tech, and promoting perovskite solar cells (PSCs).

 

Takaichi has already stressed her support for next-generation PSCs, which is touted as Japan’s next big breakthrough in clean energy. At the same time, she criticized the expansion of large-scale solar farms due to their impact on neighboring residential areas and biodiversity. Her approach supports recent trends favoring smaller, decentralized solar projects that minimize environmental and social disruption.

 

This chimes well with the direction of Japan’s next five-year infrastructure plan, administered by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). Oriented toward resilience and decarbonization, this plan is based on four principal objectives: the cultivation of sustainable local communities; the fortification of economic and societal structures via resilient infrastructure; the progression toward a green, decarbonized society; and the reinforcement of foundational support for infrastructure development.

Nuclear buff

Following her LDP leadership victory, some media forecast that Takaichi would prioritize nuclear power as a key means of reducing emissions.

At past conferences, Takaichi has demonstrated strong nuclear expertise, engaging with specifics of reactor design, safety enhancements, and fuel cycle efficiencies. This suggests she would favor a policy framework that prioritizes innovation in small modular reactors (SMRs) and advanced systems, which would alleviate the scalability issues that plague traditional nuclear sites.

Likewise, she has in the past voiced support for Mitsubishi Heavy Industries’ SRZ-1200 advanced light-water reactor, Takaichi Sanae which revealed a nuanced appreciation for nuclear tech.

During her time as Minister of State for Science and Technology Policy, she convened the Cabinet Office Expert Panel on Fusion Strategy in 2021, advocating for coordinated industrialization of Japan’s fusion capabilities. This initiative spotlighted the JT-60SA experimental reactor, a collaborative endeavor symbolizing Japan’s leadership in plasma physics and magnetic confinement fusion.

Takaichi’s endorsements reflect a forward-looking stance on energy tech, envisioning fusion as a paradigm-shifting energy source capable of delivering baseload power with minimal environmental impact.

However, these nuclear innovations will not yield electricity today and Takaichi’s most urgent task as PM would be to continue pushing forward the restart of existing nuclear power facilities. This is an issue that bested even PMs with high voter support and it will be a test of Takaichi’s diplomacy.

Trump endorsement

Takaichi has already surrounded herself with veteran allies. She appointed former Prime Minister Aso as LDP vice president, while filling other top positions with conservative figures including Suzuki Shunichi, Arimura Haruko, Kobayashi Takayuki, and Furuya Keiji – many of whom belong to the Aso faction, the LDP’s last remaining intraparty faction.

 

By relying on established networks, Takaichi signaled both loyalty to party elders and a continuation of traditional conservative priorities. Together, this lineup underscores that even amid promises of economic relief, Takaichi’s leadership will likely emphasize conservative social and political values.

 

Praised last week by President Trump in one of his social media posts, such an endorsement indicates that Takaichi’s candidacy has Washington’s prior approval and that her policies will accord with the Trump White House plans for the U.S.–Japan relations, such as boosting LNG deals and joint infrastructure projects, such as Alaska LNG.

 

LNG export deals play a central role in Trump’s plans to shrink U.S. trade deficits with Japan, South Korea, Taiwan and the EU.

Not yet the nation’s leader

Still, Takaichi’s path to national leadership is far from assured. On Friday, Oct 10, Komeito, the junior coalition partner of the LDP said it will end the arrangement citing policy differences.

 

An extraordinary Diet session to elect the next prime minister, initially scheduled for October 15 has already been delayed to allow more time for coalition talks. The LDP will now engage with other parties to shore up its base and get enough votes for the Diet to confirm Takaichi as prime minister. The main opposition party, the CDP, however, sees a chance to form its own ruling coalition.

 

The timing could not have been worse given Trump’s announced intentions to visit Japan from October 27 to 29. The new Japanese prime minister will also need to travel to South Korea to attend the Asia-Pacific Economic Cooperation (APEC) forum at the end of the month, with Chinese President Xi Jinping among the expected attendees.

 

As PM, Takaichi would face the challenge of balancing sensitive regional diplomacy with the views of her conservative backers at home. Her core supporters include groups such as the Shinto Association of Spiritual Leadership and long-standing allies like Furuya Keiji.

 

With the LDP’s minority position and pressure from all sides, even ascending the post of PM may leave Takaichi very little room to maneuver. As such, she may end up speaking about energy policies more than enacting them.

BESS Market Booming as More Non-Energy Firms Enter the Sector

With the rapid expansion of renewable energy, battery storage is moving from a supportive nche technology to one of its central drivers. Once seen as a backup tool, battery energy storage systems (BESS) are now indispensable to balancing Japan’s energy transition, ensuring stability, and fostering greater renewable penetration.

 

While recent energy headlines focus on the retreat of Mitsubishi Corp from offshore wind projects, a quieter but equally consequential shift is happening — A surge in applications to connect BESS projects to the national grid. This trend reveals both the urgency of addressing Japan’s grid limitations and the growing recognition of storage as a backbone of the decarbonized energy system envisioned in government plans.

 

Japan’s revised 7th Basic Energy Plan, released in early 2025, envisions renewables contributing up to 50% of the national energy mix by 2040. Much of this growth is expected to come from solar and wind, both onshore and offshore. Yet Japan’s grid infrastructure remains ill-prepared for such a transformation.

 

Curtailments of solar power are already common, and large-scale transmission upgrades are not expected until the 2040s. In this context, the immediate need for flexible, deployable storage is driving a short-term boom in BESS projects, with the government expecting that it will lead to around 21 GW of installations by 2040.

 

Whether this momentum will sustain at the breakneck speed of the BESS grid applications seen today – and amid changing electricity market structures and regulations – is difficult to express in empirical terms. What is clear, however, is that storage is no longer an afterthought. It’s an essential pillar of Japan’s energy future.

Growing fast, but how far?

As of June, Japan had applications for 143 GW of BESS capacity — more than double the total from just a year earlier. Applications surged by 30 GW in a single quarter, underscoring both developer enthusiasm and the urgency of grid flexibility.

 

One mid-sized international solar developer exploring the BESS sector told Japan NRG they alone had filed more than 120 grid-connected applications – the vast majority for small-scale projects in the Tokyo region.

 

Yet projects are not the same as operating capacity. The reality on the ground is that energy storage in Japan is starting from a very small base. Japan NRG data and calculations indicate that commissioned capacity stood at only about 560 MW as of July 2025.

 

As such, what will actually be delivered onto the grid over the rest of the decade is more modest. The government forecasts an initial 6–8 GW of operating BESS by 2030; this could rise to above 20 GW a decade later. These forecasts, however, and especially the 2030 number, were derived largely from government assumptions that a portion of grid connection applications will translate into operating BESS. But with application numbers rising almost exponentially, METI officials admit that this may no longer be a reliable approach.

 

The problem with the sprint to connect is that the application criteria are fairly open and do not involve large capital outlays. METI recently noted in a sector update that it now sees that many project owners are applying for connection to sites already in use or unavailable for lease. Officials are urging developers to take more time and care in their due diligence.

 

With many firms applying for over 100 projects at once, the government might cap the number of allowed grid submissions. It has become clear that a notable portion of the applications are essentially middlemen traders, seeking a quick resale of the project after securing grid access with no intention of completing it themselves.

 

This trend leads to a conclusion that official estimates for BESS development may be a stretch, based on projects that are still at an early stage. The likelihood is that less than 10% of grid-seeking capacity will materialize. The exact numbers will depend on the evolution of the regional grids, financing mechanisms, and revenue models.

Government push, incentives and uncertainties

Policy backing from METI has been a major driver of the BESS market. The ministry has three priorities as it supports the emergence of this sector: stabilizing electricity prices, improving market rules, and streamlining the grid connection process. To meet these objectives, it has leaned heavily on subsidy schemes, the most prominent of which is the Long-Term Decarbonized Power Sources Auction (LTDA).

 

The LTDA has been both a catalyst and a point of contention. The Round 1 auctions set attractive prices and spurred early enthusiasm among BESS developers. But subsequent rounds have faced criticism: Round 2 prices were seen as too low to make large-scale projects viable, while Round 3, to be held in early 2026, has set conditions that make Lithium-ion batteries less economical compared with other resources.

 

Other BESS subsidies on offer in Japan, such as the Sustainable Investment Initiative (SII), cover roughly half of the capital expenditures but come with restrictive conditions, including requirements that favor domestic battery manufacturers.

 

This patchwork of incentives has created a mixed investment climate: supportive enough to generate momentum, but fragmented enough to leave many developers cautious.

Balancing scale and speed

Developers are pursuing a range of strategies shaped by project size, interconnection timelines, and financing structures. Early movers, particularly those bringing highvoltage (HV) projects online before 2028, seem well-positioned to capture outsized profits. These smaller projects, typically 2–8 MW in scale, can reach commercial operation within 12 to 18 months, providing quick cash flow.

 

By contrast, extra-high-voltage (EHV) projects, often exceeding 50 MW, take up to five years to interconnect. While slower to mature, they offer greater scale and long-term positioning. That may be one reason that some developers are opting for mixed portfolios, balancing smaller HV projects with EHV ones to navigate upcoming policy shifts and market uncertainties.

 

Whichever size or model is chosen, nearly all market players say they face challenges in terms of grid allocation and technical constraints, land acquisition, and the unwritten rules around subsidy eligibility.

 

Many developers are adapting by scaling project sizes to align with charging limits and interconnection hurdles. This may result in projects being split into stages to accommodate on-the-ground conditions while retaining growth optionality.

Banks warm up, funds push in

Financing remains a challenge but is gradually improving as lenders and investors gain confidence in the sector. Japanese banks such as MUFG and Orix have started to participate, alongside foreign players like Société Générale. At this stage, however, financing options are still limited, partly due to the lack of know-how, directly linked to the market’s immaturity.

 

Foreign private equity and infrastructure funds are also showing an appetite for BESS. These investors typically prefer portfolios rather than single-asset deals, making aggregation an attractive strategy for developers seeking capital. Offshore financing is another emerging avenue, particularly as global players enter Japan’s market.

 

Japan’s battery storage sector is in a pivotal moment. The current boom reflects both the urgency of integrating renewables and the systemic challenges of a grid built for largely thermal baseload.

 

Policies and subsidies have primed the market for rapid growth. However, longer-term sustainability will depend on smarter market rules, better revenue models, and continued investor confidence.

 

If Japan succeeds in navigating these challenges, battery energy storage will not just be a stopgap solution, it will be a cornerstone of the country’s clean energy mix.
