Vyvanse / Lisdexamfetamine → 🇯🇵 Japan

Full details

Vyvanse / Lisdexamfetamine prohibited; penalties for import. Quantity guidance for Japan: Not approved in Japan — Vyvanse is NOT authorised and cannot be brought in legally; amphetamine salts are Class 1 narcotics under Japan's Stimulants Control Law. Documentation: No Yakkan Shoumei will be issued for lisdexamfetamine — entry is prohibited; Consult MHLW or Japanese embassy before travel. Enforcement in Japan carries fines from JPY 5,000,000 to JPY 30,000,000 and imprisonment up to 10 years in aggravated cases under Customs Law Art. 109; Narcotics Control Law; Cannabis Control Law. Because vyvanse / lisdexamfetamine is prohibited rather than restricted, there is no permit route for an ordinary traveller — attempted import is treated as smuggling regardless of intent. Arrival checks are carried out by Japan Customs (Ministry of Finance); when in doubt use the declare (red) channel — declared goods at worst attract duty or surrender, while undeclared goods attract penalties. Leaving Japan with vyvanse / lisdexamfetamine is a separate question: restricted — Vyvanse (lisdexamfetamine) is a controlled stimulant; personal export from Japan requires prescription documentation and stays within personal-use limits.

ENFORCEMENT

Active — Customs actively enforces this rule.

Leaving Japan with vyvanse / lisdexamfetamine

Lisdexamfetamine is a Schedule II-equivalent controlled stimulant under the Narcotics Control Law; Yakkan Shoumei personal-export authorisation framework. Personal-use quantities (typically ≤30-90 days' supply) accompanied by the prescription and doctor's letter are generally permitted for export from Japan; above these limits a Yakkan Shoumei from Regional Bureau of Health and Welfare is required in advance. Destination-side treatment is the sharper risk — several countries (Japan requires advance permission; some jurisdictions ban amphetamine-class medicines outright) restrict arrival with stimulant ADHD medication, so verify the arrival rule for the same route.
