Decision matrix for KMJ
These are the specific situations where this airport page earns its keep: time-zone conversion, city transfer planning, nearby airport backup logic, and source-confidence checks before acting.
When the clock matters
KMJ uses Asia/Tokyo (JST, UTC+09:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
When surface access matters
Kumamoto Airport is about 16 km from central Kumamoto; build that transfer into arrival and check-in planning.
When alternates matter
HSG Saga is the closest retained alternate at 62 km, time difference +0h.
When source checks matter
kumamoto-airport.co.jp is listed as the official airport website in the airport facts snapshot; live schedules, gates, routes, terminals, and NOTAM-sensitive operations still need official airport or airline verification.
