Japan Overflight Rules | MLIT / JCAB & Fukuoka FIR Requirements

Do You Need a Japan Overflight Permit?

Japan does not require the same separate overflight permission for every foreign civil flight. Article 126 of the Civil Aeronautics Act requires qualifying foreign aircraft to obtain permission for flights into, out of or through Japan, but expressly provides an exception for flights operated along designated airways. Foreign State aircraft and aircraft of non-Contracting States are subject to the separate permission rule in Article 126(2).

Japan Permit and Flight Support Requirements

For Japan overflight, landing, slot or trip support coordination, operators should normally provide the following details:

• Aircraft registration and aircraft type
• Operator name and full contact details
• Complete flight schedule with UTC date and time
• Departure airport and destination airport
• Full route including Fukuoka FIR entry and exit points
• ATC route and call sign / flight number
• Purpose of flight and type of operation
• Lead passenger details where applicable
• Airport slot, handling and fuel requirements for Japanese airport operations

Required Documents for Japan Coordination

• Certificate of Registration (COR)
• Certificate of Airworthiness (COA)
• Valid aircraft insurance certificate (COI)
• Noise certificate (CON)
• Air Operator Certificate (AOC) for commercial operators
• Crew and passenger details when required
• Dangerous goods declaration if applicable
• Special approval or mission documents for ambulance, humanitarian, ferry or state-related flights

Japan Lead Time

The recommended lead time for Japan overflight, landing, slot, handling or fuel coordination is usually 24 to 72 working hours when complete and accurate documentation is available. Certain operations may require longer review depending on routing, purpose of flight, landing airport, aircraft category, slot availability or authority requirements.

Short-notice flights may be coordinated on priority, subject to authority, airport and supplier acceptance. Operators should share aircraft documents, complete route, departure time, destination, purpose of flight and operational contact details at the first request stage to reduce avoidable delay.

Japan FIR Information

Japan airspace is commonly planned through Fukuoka FIR (RJJJ). Operators should verify FIR boundary estimates, ATS routing, entry and exit points and applicable flight plan addressing before operation.

Major Japanese gateways include Tokyo Haneda (RJTT/HND), Tokyo Narita (RJAA/NRT), Kansai Osaka (RJBB/KIX), Chubu Nagoya (RJGG/NGO), Fukuoka (RJFF/FUK) and Naha Okinawa (ROAH/OKA).

For complete coordination, operators may also utilize flight support services.

Japan FIR Entry and Exit Points

The following entry and exit points were provided in the original Japan permit page for route planning. Operators should verify routing against the latest approved ATS route structure before filing the flight plan.

Japan Flight Plan Submission

According to the supplied Japan AIP content, a flight plan should be submitted to the appropriate airport office or airport branch, except where a VFR flight is operated within 9 km radius of the departure point. A flight plan should not be submitted more than 120 hours prior to the estimated off-block time.

An IFR flight plan should be submitted at least 30 minutes before EOBT. For flights crossing an FIR boundary, the flight plan should be submitted according to the timing required by the concerned ATS authority. Flight plan information should be filed in UTC and in the appropriate ICAO format.

Flight Plan Information Required in Japan

The supplied Japan AIP content states that the flight plan should include core operating information required for ATS and search and rescue purposes.

• Nationality, registration marks and radio call sign
• Type and number of aircraft
• Name of pilot-in-command or formation flight leader
• Flight rules: IFR or VFR
• Departure point and estimated off-block time
• Cruising altitude and route
• First intended landing point and total estimated elapsed time
• True airspeed at cruising altitude
• Communication, navigation, approach aid and transponder equipment
• Alternate airports where applicable
• Fuel endurance, persons on board and other ATS / SAR information

Japan ATS Message Addressing

Air traffic services messages relating to traffic into or via Fukuoka FIR should be addressed to the applicable ATS units to support correct relay and delivery.

Flight Plan Delay, Change and Cancellation Messages

Delay messages should be transmitted to related ATS units when the departure of an aircraft, for which basic flight plan data has been sent, is delayed by more than 30 minutes after the estimated off-block time contained in the basic flight plan data.

Modification messages should be transmitted when changes are made to previously transmitted flight plan data. Operators should coordinate changes to route, departure time, destination, equipment, aircraft identification and other key flight plan fields before operation.

ADIZ and Unlawful Interference Notes

Flights entering Japanese territory from abroad through ADIZ should follow the applicable ADIZ procedures and ATS addressing requirements. Aircraft subject to unlawful interference should notify the appropriate ATS unit where possible, follow assigned ATC instructions where practicable, and use the relevant transponder code when required by procedure.

Major Airports in Japan

Permit2Fly can coordinate airport slots, landing support, handling, parking and fuel at major Japanese airports depending on aircraft type, schedule, operation category and supplier availability.

• Tokyo Haneda Airport (RJTT / HND)
• Tokyo Narita Airport (RJAA / NRT)
• Kansai International Airport, Osaka (RJBB / KIX)
• Chubu Centrair International Airport, Nagoya (RJGG / NGO)
• Fukuoka Airport (RJFF / FUK)
• Naha Airport, Okinawa (ROAH / OKA)
• New Chitose Airport, Sapporo (RJCC / CTS)

Overflight Charges, Airport Slots and Navigation Fees

Japan overflight, navigation, airport and handling charges may depend on the type of aircraft operation, route, aircraft weight category, airport, slot requirement and services requested. Where landing is involved, operators should also consider parking, ground handling, fuel uplift, supervision, passenger handling, cargo handling and any additional airport or supplier charges.

Airport slots and parking availability can be critical at major Japanese airports, particularly Tokyo Haneda, Tokyo Narita, Kansai Osaka and other busy international gateways.

Operational Restrictions and Special Approvals

Certain flight categories may require additional review or longer coordination time. Operators should provide complete information early when the flight involves special cargo, state-related movement, dangerous goods, ambulance operation or unusual routing.

• Military, diplomatic or state flights
• Dangerous goods or special cargo flights
• Ambulance, medevac and humanitarian missions
• Survey, inspection, ferry or delivery flights
• Flights with restricted cargo or unusual routing
• Flights requiring landing permit, airport slot, passenger handling or cargo handling

Landing Permit, Handling and Fuel Support

If your aircraft will land in Japan, you may require international landing permits along with full global flight support services.

Our flight operations support can also assist with airport coordination, service confirmation, schedule revision, supplier follow-up and communication with the operator until flight completion.
