Can I bring benzodiazepines into Japan for personal use?
Possibly, but check the exact active ingredient and quantity before travel. Benzodiazepines can fall under Japan's controlled narcotic, psychotropic or stimulant-related rules, so the ordinary personal-import allowance is not enough by itself; advance Narcotics Control Department / import documentation may be required.
