総務省｜統計基準等｜日本標準産業分類

This page describes Japan's Standard Industrial Classification maintained by the Ministry of Internal Affairs and Communications. The classification serves as a statistical standard for displaying statistics by industry, categorizing all economic activities involved in producing or providing goods and services. It functions as a technical standard for government agencies compiling statistical survey results by industry, not for determining individual business classifications or administrative dispositions. The current classification is the 14th revision announced in July 2023 (effective April 2024). The page also provides information on past revisions, correspondence with the International Standard Industrial Classification (ISIC), and guidance on using the classification search system.
