Japan's Share of the Semiconductor Supply Chain

Equipment and materials by country

Japan is a smaller producer of chips than Taiwan, South Korea or the United States, but its companies supply a large part of the tools and materials every fab needs. The charts below are METI's breakdown of global sales by the home country of the supplier, based on OMDIA data for fiscal 2021.

What has changed since

In a December 2025 review, METI noted that Japan's share of equipment sales shrank between 2021 and 2023, most visibly in the large markets for lithography, thin-film deposition and etching equipment. Japanese companies remain strongest in narrower steps such as coat/develop, cleaning, dicing and test. See where Japanese equipment makers lead for the step-by-step picture, and semiconductor materials where Japan leads for the materials side.
