Foreign investment in Japan’s chip industry has reached 6 trillion yen (about $37 billion), and this figure is expanding further with recent announcements from Sony Group and TSMC to build image sensor factories. TSMC has already invested 3 trillion yen in its two wafer fabs in Japan. The first fab began mass production of logic chips in 2024, and the second is currently under construction. Last month, Micron Technology launched an expansion project at its Hiroshima plant, planning to invest 1.

Foreign enterprises have invested up to 6 trillion yen (approximately $37 billion) in Japan's chip industry, and this figure has further expanded following recent announcements by Sony Group and TSMC regarding the construction of image sensor factories. TSMC has invested 3 trillion yen in its two wafer fabs in Japan. The first fab began mass production of logic chips in 2024, while the second one is currently under construction. Last month, Micron Technology launched an expansion project at its plant in Hiroshima Prefecture, planning to invest 1.5 trillion yen to produce advanced memory chips that are vital for artificial intelligence data centers. Similarly, in July, Israeli chip maker Tower Semiconductor announced an investment of 600 billion yen to mass produce optical communication device chips used in data centers.
