Japan drone rules: 100g registration and the permit maze
Verify before you fly

Japan has the strictest default airspace of the eight jurisdictions we cover. Under the Civil Aeronautics Act, any unmanned aircraft weighing 100g or more (including battery) must be registered before flying — a threshold that captures nearly every camera drone travellers pack. Registration brings a registration ID that must be displayed on the aircraft, plus an onboard remote ID function. Aircraft at 100g or below are treated as model aircraft, though altitude and airport-approach rules still reach them.
Where you cannot fly without permission
MLIT's rules divide restrictions into airspace and flight methods. Permission or approval — applied for through the online DIPS 2.0 system, normally about 10 business days in advance at the Regional Civil Aviation Bureau — is needed for:
| Restricted airspace (permission) | Restricted flight methods (approval) |
|---|---|
|

That first row explains "why can't I fly in Tokyo?": the city's central wards are designated DID, and flying there needs advance permission, not a spot decision.
The category and pilot-certificate system
Japan also runs operational categories (from uninvolved-person Level 1 up to Level 4 — flight over people in inhabited areas), with higher levels requiring a UA Remote Pilot Certificate and, for the top levels, a certified aircraft flying under approved Flight Operation Rules. One point MLIT states explicitly: Japan's pilot certification systems "are unique to Japan and different from those of other countries — you cannot fly under the qualification or certification systems of other countries."
Obligations after you get permission
- Report your flight plan (date, route, altitude) to MLIT before flying.
- Keep flight logs: journey logbook, daily inspection and maintenance records.
- Report accidents and serious incidents regardless of whether permission was held.
- Comply with the Radio Act for any transmission equipment, and never fly under the influence of alcohol or drugs, carelessly or recklessly.
Key takeaways
- Register from 100g — before you fly, not on the day.
- Most city cores are DID: no permission, no flight.
- Default mode is daytime, line of sight, 30m from everyone and everything.
- Permits go through DIPS 2.0 with roughly 10 business days of lead time.
- Foreign certificates do not substitute for Japanese ones.
Compact drone cases for Japan travel
Japan's rules push flying to rural fields and parks — usually reached by train. A slim hard case that fits overhead racks makes the trip realistic. Compare current options sized for folding drones.

Registration applies to anyone flying a 100g-plus drone in Japan regardless of nationality, and applications run through the same DIPS 2.0 portal. MLIT operates an English help desk (+81-3-5539-0225, weekdays 9:00–17:00 JST) for registration and permission questions. More on planning a Japan drone trip in the tourist guide.
