｜Toyota to Establish New EV Battery Plant in Japan's "Silicon Island" Kyushu
Toyota Motor has announced it will make 5 trillion yen ($32 billion) in EV-related investments by 2030. Toyota already has battery plants in the prefectures of Aichi, Hyogo, and Shizuoka and plans to construct an EV battery plant in Kyushu. Toyota intends to invest 300 billion yen in its joint venture with Panasonic Holdings, the Himeji plant.

Kyushu, known as Japan's "Silicon Island," is home to numerous semiconductor and image sensor suppliers crucial to the EV and autonomous driving industries. Integrating the supply chain for key EV components (batteries and semiconductors) in Kyushu will enhance production and advance technological development. The new battery plant will be located 40 kilometers from Toyota's Miyata plant, which assembles Lexus vehicles. This plant has an annual production capacity of 430,000 units, with 90% primarily exported to other Asian regions. The new battery plant will become the main battery supplier for the Miyata plant.

Toyota aims to sell 3.5 million electric vehicles annually by 2030. The plant will be operated by Toyota's battery manufacturing subsidiary, Primearth EV Energy. Japan's Ministry of Economy, Trade and Industry is expected to subsidize the project under the Economic Security Promotion Act.

｜SK oceanplant and Anma Offshore Wind Power Renew Substructure Contract
SK oceanplant announced an agreement with Anma Offshore Wind Power to extend their contract. Under this agreement, SK oceanplant will manufacture and supply the jacket substructures for the Anma offshore wind farm. The Anma offshore wind project, located 40 kilometers off the coast of Yeonggwang County, Jeollanam-do, has an installed capacity of 532 MW. SK oceanplant is expected to provide jacket substructures for 38 wind turbines, each with a capacity of 14 MW.

SK oceanplant has secured 200 offshore wind substructure orders in Taiwan and Japan. This contract renewal strengthens the partnership between the two companies.

｜Komai Haltec Plans to Manufacture Offshore Wind Turbine Towers in Chiba; Targeting the European Market
Despite the lack of large-scale wind turbine manufacturers domestically, the major Japanese bridge company Komai Haltec plans to invest approximately 5.5 billion yen to produce offshore wind turbine towers at its Chiba Prefecture plant by 2026, introducing equipment capable of processing thick steel plates. The factory will be equipped with processing and welding facilities to accommodate 15 MW turbines, with an estimated annual production capacity of 10 towers, projected to increase to 30 towers per year by 2031. The company aims to enter the offshore wind market by leveraging its thick steel processing technology to reduce the high transportation costs from China and Southeast Asia to Japan. In terms of technological development, the company will advance tower processing and painting robots, automatic welding inspection systems, and other innovations to achieve a 20% reduction in processing costs. The government's goal is to increase the localization rate of the offshore wind supply chain to 60% by 2040.
