On December 17, 2024, Japan’s Ministry of Agriculture, Forestry, and Fisheries (MAFF) invited public comments on a revision to the Japanese Agricultural Standards (JAS) for miso (fermented soybean paste seasoning). The JAS standard for miso was first introduced in 2022. This revision proposes specifying the input ingredients permitted for producing JAS-certified miso. MAFF will accept comments in Japanese only, with a deadline of January 15, 2025.
