Overview
- Kunio Kuroki, a 37-year-old company executive from Onojō, was arrested July 25 by Fukuoka Prefectural Police, Moji Customs and Kyushu Narcotics Control Department on suspicion of violating the Cannabis Cultivation Regulation Law.
- Investigators say Kuroki smuggled 11 untreated cannabis seeds into Fukuoka Airport on April 16 concealed in a portable ashtray within his carry-on after purchasing them at a cannabis shop in Thailand.
- The Cannabis Cultivation Regulation Law, promulgated in December 2023, began banning the import of any untreated cannabis seeds in March 2025 to close previous legal loopholes.
- Kuroki told authorities he was unaware that bringing seeds from overseas violated the new import restrictions, underscoring gaps in public awareness about the updated law.
- Officials have launched a joint investigation and intensified outreach campaigns to raise compliance as they apply the seed ban for the first time nationwide.
