SEMICON Japan 2026 Tokyo: Chip Supply Chain Show Guide
By Ilyas Kerbal,
SEMICON Japan is Japan’s main semiconductor exhibition and a key event for the global equipment and materials supply chain, where Japanese companies such as Tokyo Electron, Screen, Advantest, Shin-Etsu and JSR lead the world. The 2025 edition drew 121,267 visitors and 1,216 exhibitors from 35 countries. With Rapidus, TSMC’s JASM fab and Kioxia driving new investment, the show has become a priority for overseas suppliers. SEMICON Japan 2026 runs from 9 to 11 December at Tokyo Big Sight, and the attendee list connects you with Japan’s chipmaking decision-makers.
