Is CBD legal in Japan?
- Legal status
- CBD (cannabidiol) is legal only if THC is below the MHLW residue limits introduced by the December 2023 Cannabis Control Act amendment (effective 12 Dec 2024): 10 ppm in oils/fats and powders, 1 ppm in other solids, and 0.1 ppm in aqueous solutions; any product over the limit is a controlled narcotic.
- Consequences if caught
- A CBD product above the residue limits is a narcotic (mayaku) and possession/import is a narcotics offence; the 2023 reform also newly criminalised cannabis use itself. A common overseas 0.3%-THC full-spectrum oil equals about 3,000 ppm, far over the limits.
- If prescribed or medical
- The 2023 reform created a legal route for cannabis-derived pharmaceuticals (enabling Epidiolex-type approvals); compliant sub-limit CBD remains legal.
- Documentation
- Carry a component-analysis certificate (seibun-bunsekisho) proving THC below the 10/1/0.1 ppm residue limits; a full-spectrum overseas oil cannot be legalised by paperwork.
