Appendices classification: - Appendix I: Most stringent. Commercial trade is generally prohibited (only permitted for scientific purposes) - Appendix II: Export permit from the country of origin is required - Appendix III: Export permit from the country of origin is required
Verification method: Species can be searched in the Ministry of the Environment's CITES database (https://www.env.go.jp/nature/cites/).
