About this page

This page announces the Ministry of Health, Labour and Welfare's decision on September 14, 2016 to designate three substances (zopiclone, etizolam, and phenazepam) as Class III psychotropic drugs. This brings the total number of psychotropic drugs to 83. Two of these substances are distributed as domestic pharmaceuticals, with strengthened regulations and penalties. Phenazepam has no domestic pharmaceutical distribution but is regulated due to international treaty requirements. The ministry will notify relevant organizations and raise awareness to prevent misuse and ensure proper use.
