Smart Energy Week 2025 in Tokyo emphasized the shifting energy priorities of Japan, where officials PEROVSKITE SOLAR promotes PV Expo and companies that present a fixed state battery technology at Battery Japan.
Smart Energy Week 2025, held 19-21 February at Tokyo Big Sight, showed advanced technologies of more than 1,600 exhibitors in 40 countries, with breakthroughs in perovskite solar cells and batteries come to the attention. The event unfolded under clear, sunny skies, with the snow-covered peak from Mt. Fuji Visibly from Central Tokyo a suitable background to PV Expo, Battery Japan and other exhibitions that emphasize the Japanese aggressive energy transition and innovation leadership.
The timing was also considerable and just after the approval of the Japanese cabinet of the 7th strategic energy planaimed at a reduction of 73% in greenhouse gas emissions by 2040 and carbon neutrality by 2050. The plan includes the disasters of renewable energy sources up to 40% to 50% of the power mixture while the nuclear power is restored to 20% through the next generation-a striking post-fukhima-addiction.
Nobuo Tanaka, former executive director of the International Energy Agency (IEA), opened the week with a keynote speech about the continuous renewable energy sources and electrification sp been of China. He called for the development of a regional hydrogen supply chain in Asia and urged Japan to collaborate with Zuid -Korea and the United States for energy security.
“We are now at a turning point, with geopolitical risks that are globalized,” said Sadanori ITO, a special adviser from the Ministry of Economy, Trade and Industry (Meti), and notes that the relatively recent shift of Japan from a feed-in rate (Fit) to a feed-in premium (FIP) system. “We would like to design a system that will not be bothered by industry and business, but will rather promote growth.”
Perovskiet solar cells were a focal point at PV Expo Japan 2025. Meti has announced an investment of $ 1.5 billion in ultra -thin, flexible solar panels of Perovskiet to accelerate the acceptance of renewable energy, to reduce the dependence on fossil fuels and counteract China’s dominance in the sector. Kyodo News recently noted That Sekisui receives chemical government subsidies to expand the production, with Meti predicting that the solar capacity of Perovskiet 20 GW could reach by 2040 on JPY 10 ($ 0.07)/W.
With the strategic control of Japan about iodide reserves, the country is ready to lead in the development of Perovskiet, which tackles the concerns of land scarcity by innovative new legislative imperatives such as the new solar mandate from Tokyo. From 1 April 2025, the mandate requires solar panels on new houses, which may add 1 GW to 1.5 GW capacity per year in the vast national capital.
“We have very high expectations for Perovskite PV,” said Masaya Sasaki, director of the building environment at the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
Ministry of Environmental Officer Noriaki Yoshino added that the government strives to develop perovskiet cells, stimulate self-consumption and improve PV waste recycling. This focus on lightweight equipment could be seen on the new BIPV World exhibition, co-organized with the Japan Photovoltaic Energy Association (JPEA). The special stand in the spotlights of the urban solar -zonne integration, which lies the core of the dedication of Japan for renewable energy in its densely populated cities.
While PV Expo Japan 2025 showed the changing focus of the country on more adult solar markets and technologies, the atmosphere was considerably more modest compared to the “Gold Rush” era of 2015, when generous fit subsidies attracted large crowds and larger Western participation. Battery Japan 2025, on the other hand, has attracted more international attention this year, so that Japan’s battery leadership underlines Japan’s battery.
The bottom floor at Battery Japan 2025 buzzed with activity, because companies such as micro -proof and Panasonic show innovations that are crucial for the growing renewable energy infrastructure, which emphasizes the global demand for advanced storage solutions as the country scales up its renewable capacity.
