日本开出“半价建厂+全补贴”，三星与SK海力士仍对赴日投资保持谨慎

Core Viewpoint - The Japanese government has offered attractive investment conditions for South Korean semiconductor giants Samsung Electronics and SK Hynix, but both companies have not made substantial investment decisions due to domestic pressures and stakeholder constraints [1][2]. Group 1: Investment Conditions - The cost of building a semiconductor factory in Japan could be about half that of South Korea, with comprehensive policy support from the Japanese government [2]. - The Japanese government provides a "full support package," including tax incentives, infrastructure assistance, labor support, and connections with local equipment suppliers, contrasting with the lack of substantial incentives in South Korea [2]. Group 2: Domestic Pressures - Samsung and SK Hynix's hesitation to invest in Japan is primarily due to domestic public opinion and pressure from government and local stakeholders [2]. - Despite the financial advantages of establishing factories in Japan, external constraints appear to outweigh these benefits [2]. Group 3: Competitor Expansion - In contrast to the cautious approach of South Korean companies, TSMC and Micron are rapidly expanding in Japan, with TSMC receiving up to 476 billion yen in subsidies for its Kumamoto factory [3]. - TSMC plans to produce Japan's first 3nm chips with a total investment of approximately 17 billion USD (about 2.6 trillion yen) [3]. - Micron is also strengthening its presence in Japan, planning to invest 1.5 trillion yen (96 billion USD) in a new HBM chip factory in Hiroshima, with construction starting in May [3]. Group 4: Additional Investments - Western Digital announced that its capital investments in Kioxia's factories in Yokkaichi and Kitakami have been certified by the Japanese Ministry of Economy, Trade and Industry, qualifying for investment subsidies [4]. - The total support for these factories includes up to 150 billion yen, along with an additional 92.9 billion yen under a specific semiconductor production facility development plan approved in July 2022 [4].
