Codeine (Tylenol #3, co-codamol)
Codeine phosphate / dihydrocodeine · ジヒドロコデインリン酸塩
Codeine sits on both sides of Japan's rules. Products with more than 1% codeine or dihydrocodeine, including Tylenol #3 and most co-codamol, are narcotics and need an import permit before you arrive. Weak dihydrocodeine cough syrups and cold tablets are sold OTC in Japan, so mild cough relief is easy to find locally.

Can I bring Tylenol #3 or co-codamol into Japan?
