No, throwing stars (shuriken) are prohibited under Japan’s Swords and Firearms Possession Control Law, enforced by the National Police Agency. While decorative replicas may be sold, functional or sharpened shuriken are classified as “offensive weapons,” carrying penalties up to 15 years imprisonment or fines exceeding ¥500,000. Local ordinances in major cities like Tokyo further restrict their display or transport.
Key Regulations for Throwing Stars (Shuriken) in Japan
- Prohibited Classification: Shuriken are deemed “offensive weapons” under Article 2 of the Swords and Firearms Possession Control Law, regardless of blade sharpness or intended use. Possession without explicit police authorization is illegal.
- Replica Restrictions: Non-functional, blunt-edged shuriken sold as “decorative items” must comply with the 2023 amended ordinances by the Metropolitan Police Department, requiring certification labels and retail-only sales to adults.
- Transport & Display: Carrying shuriken in public spaces, including vehicles or luggage, triggers automatic suspicion under the 2026 National Police Agency enforcement guidelines, mandating immediate confiscation and potential prosecution.
Local prefectural police (e.g., Osaka Prefectural Police) conduct periodic inspections of martial arts supply stores, seizing uncertified shuriken. Foreign nationals face heightened scrutiny under immigration compliance measures, with violations potentially leading to deportation.
