Drone Batteries (LiPo) → 🇯🇵 Japan

Full details

Drone Batteries (LiPo) restricted; documentation or permits may apply. Quantity guidance for Japan: ≤100 Wh in carry-on; 101-160 Wh with airline approval; MLIT follows IATA DGR; LiPo batteries must be in protective cases. Documentation: Airline approval for 101-160 Wh batteries; MLIT drone registration certificate if operating in Japan. Enforcement in Japan carries fines from JPY 100,000 to JPY 5,000,000 under Customs Law (Kanzeihō) Art. 110, Art. 111 (ordinary personal cases are handled as civil infringements). Restricted status means compliant carriage is achievable with the right paperwork and quantities; the practical risks are seizure, duty, and delay rather than criminal liability for a good-faith traveller. Arrival checks are carried out by Japan Customs (Ministry of Finance); when in doubt use the declare (red) channel — declared goods at worst attract duty or surrender, while undeclared goods attract penalties. Leaving Japan with drone batteries (lipo) is a separate question: allowed — Spare drone batteries may be taken out of Japan freely but must travel in cabin baggage under lithium-battery aviation rules.

Leaving Japan with drone batteries (lipo)

Spare drone batteries face no customs export control from Japan. IATA dangerous-goods rules require all spare lithium batteries to travel in cabin baggage with terminals protected; most consumer-drone batteries are under 100 Wh and travel freely, while 100-160 Wh packs need airline approval (max two). Batteries installed in the drone may travel in checked baggage with the device powered fully off, though cabin carriage is recommended.
