Registration of Chemicals in Japan

There is no harmonised registration regime for existing chemical substances in Japan. All commercially available substances are included in the METI list and have individually assigned numbers (METI numbers). Accordingly, listed substances can be directly imported or produced in Japan without prior registration.

If no METI number is provided, chemicals are considered new and have to be registered before they are made available on the Japanese market. Three authorities (METI, MHLW, MOE)1 share the responsibility for new chemicals registration.

Japanese regulations for new chemicals registration are quite unique due to their high emphasis on environmental safety. The CSCL (Chemical Substances Control Law) focuses on the prevention of environmental pollution and its impact on human health, fauna, and flora, while the ISHL (Industrial Safety and Health Law) secures the workplace health and safety. The key endpoint for new chemical registration is ready biodegradation. Substances having successfully passed the MITI test (OECD 301f) as readily biodegradable can be directly notified. For not readily biodegradable substances, the regulation requires applicants to identify and quantify transformation products as well as conduct a bioaccumulation and partition coefficient tests. Depending on the outcome of these tests, further toxicity and ecotoxicity tests may be required.
