No. Kratom is illegal in Japan under the Narcotics and Psychotropics Control Act, classified as a designated stimulant since 2014. Possession, sale, or importation risks severe penalties, including imprisonment up to 10 years or fines exceeding ¥10 million. The Ministry of Health, Labour and Welfare (MHLW) enforces strict monitoring, with recent 2026 compliance directives targeting online vendors exploiting legal loopholes.
Key Regulations for Kratom in Japan
- Designated Narcotic Status: Kratom and its alkaloids (mitragynine, 7-hydroxymitragynine) are explicitly listed under the Narcotics and Psychotropics Control Act, prohibiting all non-medical use.
- Strict Import Bans: The Customs Act enforces zero-tolerance for kratom imports, with seizures escalating under MHLW’s 2025–2026 enforcement directives targeting air cargo and postal services.
- Criminal Liability: Violations incur penalties under the Penal Code, with aggravated cases (e.g., distribution to minors) leading to harsher sentences, as outlined in the 2024 amendments to the Act on Punishment of Acts Related to Narcotics.
