Plant Protection Act and Insect Import Regulations
The Plant Protection Act is a law designed to prevent the invasion of plant pests and diseases from overseas. It is the most directly applicable regulation to insect imports, and violations incur severe penalties.
Prohibited imports: Most live insects fall under prohibited import categories. Particularly, species that could become agricultural pests (some Scarabaeidae, Chrysomelidae, etc.) are strictly restricted
Beetle and stag beetle imports: Foreign-bred rhinoceros beetles and stag beetles may be allowed to import after inspection by the plant quarantine service. However, importing them with soil or plant matter attached is prohibited. Import is only permitted for adult insects in a clean condition
Import inspection procedures: When importing, submit an "Import Inspection Application Form" to the plant quarantine service and undergo inspection. If pests or diseases are detected, the shipment will be disinfected or destroyed
Personal import precautions: Bringing back insects purchased overseas during travel is also subject to the Plant Protection Act. Inspection must be conducted at the airport's plant quarantine counter. Bringing in insects without following procedures is punishable as smuggling
Penalties: Violations result in imprisonment for up to 3 years or fines up to ¥3 million (up to ¥50 million for corporations). More severe penalties may apply in egregious cases
Invasive Species Act (Act for the Prevention of Damage to Ecosystems Caused by Designated Invasive Species, etc.)
The Invasive Species Act is a law that regulates non-native species that may damage ecosystems or human health. There are insect species that fall under this regulation.
Insects designated as invasive species: Western honeybees, yellow-legged hornets, red imported fire ants, and fire ants are among those designated. Breeding, transporting, releasing, and selling these insects are principally prohibited
Undetermined invasive species: Non-native species with unclear impact on ecosystems may be classified as "undetermined invasive species." Notification to the relevant minister is required before import
Management of invasive species in captivity: Individuals that were being bred before being designated as invasive species may be allowed to continue breeding with proper notification. However, strict management standards must be met
Prohibition on insect release: Releasing foreign-bred insects into the wild is a serious threat to ecosystems, not just under the Invasive Species Act. If you can no longer keep an insect, take responsibility to manage it through its end or find an appropriate facility to take it
Penalties: Illegal breeding or release of designated invasive species results in imprisonment for up to 3 years or fines up to ¥3 million for individuals. Fines up to ¥100 million for corporations
CITES (Washington Convention) and Insects
CITES is a convention that regulates international trade in wild fauna and flora, and insects are no exception. Some beautiful and rare species are subject to protection.
Appendix I (commercial trade principally prohibited): Some Ornithoptera species (such as Alexandra's parrot-wing swallowtail) are listed. These are considered among the world's most beautiful butterflies, and trade in specimens is regulated
Appendix II (permits required): Most Ornithoptera species and Parnassius genus are listed. Trading is possible with export permits, but document verification is essential
Appendix III: Species for which specific countries have requested protection. Some butterflies may be included
Domestic handling: When purchasing specimens or live specimens of CITES-listed species, verify certificates of legal import. Purchasing illegally imported specimens may also be illegal
Species to be cautious about: When purchasing large, beautiful foreign-bred species, develop a habit of checking in advance whether they are CITES-listed. Confirming with the seller is standard practice
Regulations on Collecting and Breeding under Domestic Law
There are several restrictions on collecting insects within Japan based on various laws and ordinances. Caution is necessary as it is not uncommon to unknowingly violate these rules.
Act on the Conservation of Endangered Species of Wild Fauna and Flora: Collecting and transferring insects designated as endangered wild fauna and flora are prohibited. Examples include Yanbar long-horned beetles and bordered diving beetles
Natural monuments: Collection of insects designated as natural monuments is prohibited under the Cultural Properties Protection Act. Some are designated as natural monuments at the regional level, such as horseshoe crabs (which are not strictly insects)
Natural Parks Act: Collection of all fauna and flora, including insects, is prohibited in specially protected areas of national parks and quasi-national parks. Collection restrictions may also apply in special areas
Local ordinances: Prefectures and municipalities may have their own ordinances regulating insect collection. Tokyo has ordinances protecting endemic species such as the Ogasawara fritillary
Collecting on private land: Permission from the landowner is required to collect insects on someone else's property. Unauthorized collecting on forests or agricultural land can cause disputes
Rules on Sales and Trading
There are legal requirements for selling insects as well. When selling bred individuals as a hobby, check the following points:
Animal dealer registration: Insects fall outside the scope of the Animal Protection and Management Act, so animal dealer registration is not required in principle. However, selling feeder animals that are mammals, birds, or reptiles requires separate confirmation
Act against Unjustifiable Premiums and Misleading Representations: Online sales (online auctions, flea market apps, etc.) may fall under this law. If selling repeatedly and continuously as a business, labeling under this act is required
Used Goods Business Act: A used goods dealer license may be required when buying and selling insect specimens as a business. This applies to purchasing and selling used specimens
Obligation to file tax returns: If annual profit from selling insects exceeds ¥200,000, filing a final tax return is necessary. Tax obligations arise even for hobby-related sales
Regulations on shipping live insects: When sending live insects by delivery, check each shipping company's terms and conditions. Some shipping companies restrict handling of live specimens
Recent Legal Amendments and Future Outlook
Regulations concerning insects change in response to social conditions and ecosystem impact assessments. Stay informed of the latest developments.
Review of the Invasive Species Act: The Invasive Species Act is regularly reviewed, and regulated species may be added. Research particularly focuses on the impact of foreign-bred stag beetles on native species
Strengthening online trading regulations: Insect trading on flea market apps and social media is increasing, and some point out that it has become a breeding ground for illegal transactions. Stricter regulations are expected in the future
Connection to the Basic Biodiversity Conservation Law: As biodiversity conservation becomes an international priority, regulations on insect collecting and trading may be further strengthened
Microplastics and breeding supplies: Awareness of the environmental impact of plastic products used in insect breeding is increasing. A shift toward biodegradable materials may occur
