As wind power momentum slows in Japan, can tech help the industry get back on track?

What happened: Japan's offshore wind build-out has slowed since its 2021 targets, with Mitsubishi Corp. exiting the field in mid-2025 and environmental and fishing concerns delaying projects. Tech such as bird detection systems is being tested as a partial fix. Key numbers: Targets are 10 GW by 2030 and 30 to 45 GW by 2040. Why it matters: Experts say rapid offshore wind expansion is needed for Japan's Paris Agreement and 2050 net-zero plans, and delays could open the door to more fossil fuel or nuclear use. Environmentalists want bird protection and earlier consultation built into siting.
