J-Lex is now live — an English-based database of pharmaceuticals available in Japan.

We are pleased to announce the launch of J-Lex, a searchable online reference designed to help healthcare professionals, researchers, and industry partners navigate Japan’s pharmaceutical landscape with clarity and confidence.

The database provides essential information on medicines marketed in Japan, including product names, active ingredients, manufacturers, and therapeutic categories — all presented in English for ease of use.

We will continue to update and expand the database to improve accuracy, coverage, and usability.

Thank you for using J-Lex.
