Foreign investment in Japan's semiconductor sector totals 6 tln yen (about $37bn); recent image‑sensor fab announcements from Sony and TSMC will add to overall sector investment. TSMC has committed 3 tln yen to two Japanese wafer fabs — the first began volume production of logic chips in 2024, the second is under construction. Micron last month started an expansion in Hiroshima, planning 1.5 tln yen to produce advanced memory chips for AI data centers. In July Tower Semiconductor said it will in
