Registering a drone under the Civil Aeronautics Act (航空法) is mandatory for almost every unmanned aircraft in Japan, but it does not authorize where or how you can fly it. A separate flight permission from MLIT (国土交通省, Ministry of Land, Infrastructure, Transport and Tourism) is required whenever the operation crosses one of several fixed thresholds: densely populated areas, airport proximity, altitude, night flight, beyond visual line of sight, crowds, or hazardous payload.
Does Drone Registration in Japan Cover Flight Permission Too?
No. Registration and flight permission are two separate steps under the Civil Aeronautics Act, and completing one does not satisfy the other. Registration (機体登録) applies to any unmanned aircraft weighing 100g or more and produces a registration number (機体登録記号) that must be physically displayed on the airframe.
Remote ID transmission is also required during flight unless the operator qualifies for a specific exemption. None of this addresses where the drone is allowed to fly. That question is governed by a separate set of operating conditions, and if any of them apply, registration status is irrelevant until MLIT permission is obtained.
Which Flight Conditions Trigger a Mandatory MLIT Permission?
Four categories of operation require advance MLIT permission regardless of whether the drone is properly registered. First, flight inside a Densely Inhabited District (DID) requires permission at any altitude, with no low-altitude exception. Second, flight near airports, within the boundaries of published exclusion zones, requires permission independent of DID status.
Third, flight above 150 meters above ground level requires permission everywhere in Japan, not only near airports or population centers. Fourth, flight at night, beyond visual line of sight (BVLOS), over crowds, or carrying a hazardous payload requires permission and frequently a Class II unmanned aircraft pilot license (二等無人航空機操縦士) or equivalent demonstrated skill. Where none of these four conditions apply, registration alone is sufficient and no separate permission is required.
What Are Japan's Drone Flight Levels and Operational Categories?
Japan layers two classification systems on top of registration, and both determine what certification a given flight actually needs. Flight Levels (1 through 4) describe the operational profile by population density and visual line of sight, while Operational Categories (I, II, III) describe third-party risk exposure and drive licensing requirements.
Level 1 is visual line of sight (VLOS) flight with no people in the operating area, and Level 2 is VLOS flight with people present but outside the flight path. Level 3 is beyond visual line of sight (BVLOS) over non-populated areas with no third parties under the flight path. Level 4, the most restrictive, is BVLOS flight over populated DID areas with third parties potentially under the flight path.
Level 4 maps to Category III risk and is the only tier that requires the full certification stack: Type Certification (型式認証) of the aircraft itself, Aircraft Certification (機体認証), a Class I unmanned aircraft pilot license (一等無人航空機操縦士), and per-flight operational approval from MLIT. A survey or inspection drone operated in daytime VLOS outside a DID will typically sit at Level 1 or 2 and never touch this stack at all.
Key points:
(a) Registration under the Civil Aeronautics Act is required for any drone 100g or heavier, but it is a manufacturing and ownership record, not a flight authorization.
(b) MLIT flight permission is a separate, condition-triggered requirement: DID flight, airport-zone flight, altitude above 150m AGL, night flight, BVLOS, crowd overflight, or hazardous payload each independently trigger it.
(c) Outside those conditions, in daytime VLOS operation below 150m AGL and away from a DID or airport zone, registration alone is sufficient and no MLIT permission application is needed.
What Other Compliance Layers Apply to an Imported Drone?
Flight permission is a domestic operating question, but a drone entering Japan carries at least two additional compliance layers that sit outside the Civil Aeronautics Act entirely. Unmanned aircraft fall under HS heading 8806, which places them in a FEFTA (外為法, Foreign Exchange and Foreign Trade Act) controlled category subject to export and import screening. That screening is a distinct determination from flight permission and depends on the specific unit's configuration; it is not addressed by registering the aircraft or obtaining a flight permit.
Separately, a drone using a 2.4GHz or 5GHz control link needs technical conformity certification (技適, giteki) under the Radio Act (電波法) before the radio link can be legally operated in Japan. This is a distinct certification track from both registration and flight permission, and it needs to be checked on its own before the drone is put into service.
Getting the flight-compliance side right is only half the picture for an imported unit. The import structure itself, who is named as importer, how HS 8806 is classified, and whether a non-resident manufacturer needs an Attorney for Customs Procedures (ACP) arrangement or a full import-of-record structure, is covered in Japan IOR for Drones, Robotics, and Industrial Automation Equipment. For a broader comparison of which non-resident import structure fits a given drone program, see IOR vs EOR vs ACP: Which Japan Market-Entry Structure Do You Actually Need, and for background on how an Attorney for Customs Procedures role is structured, see the dedicated overview. Aplash's ACP service page covers the non-resident import-of-record side for readers who have already sorted out flight compliance and need the customs structure next.
Frequently Asked Questions
Do I need MLIT permission every time I fly a registered drone in Japan?
Not necessarily. If the flight stays below 150 meters above ground level, remains within visual line of sight, occurs in daytime, avoids Densely Inhabited Districts and airport exclusion zones, and does not fly over crowds or carry a hazardous payload, registration under the Civil Aeronautics Act is sufficient on its own. The moment any one of those conditions changes, a separate MLIT permission application becomes necessary for that specific operation.
What happens if I fly a drone in Japan without a required MLIT permission?
Flying under conditions that require MLIT permission without having obtained it is a violation of the Civil Aeronautics Act and carries regulatory enforcement exposure. The specific consequences depend on the nature of the violation and are determined case by case; this article does not substitute for a review of your specific flight plan against current MLIT requirements before you fly.
Does one MLIT flight permission cover multiple flights or locations?
The scope of a permission is defined by what was applied for, typically a specific site, period, and set of operating conditions, rather than a blanket authorization for all future flights. Operators whose flight plans change location, add BVLOS segments, or extend into night operation generally need to confirm whether their existing permission still covers the new conditions or whether an amendment or new application is required.
Conclusion
Registration under the Civil Aeronautics Act is the baseline every drone operator in Japan needs, but it answers a different question than flight permission does. The two run on separate tracks, and a fully registered drone can still be operated illegally if it crosses a DID boundary, an airport exclusion zone, the 150m altitude line, or flies at night, BVLOS, over crowds, or with a restricted payload without the matching MLIT permission in hand.
