How to get into lounges at KMJ.
Kumamoto has a single lounge, so access is straightforward. Lounge ASO is a Japanese card lounge: it admits holders of eligible credit cards, premium-cabin and status passengers on ANA (Star Alliance) and JAL (oneworld), and walk-in visitors paying at the door. There are no separate airline-branded lounges at KMJ — everyone uses the same airside space on the third floor of the terminal.
Eligible credit cards
As a typical Japanese card lounge, Lounge ASO admits holders of eligible credit cards — the most common way in for domestic travellers. Present your card with your boarding pass at the entrance; check your card's terms, as guest charges may apply.
ANA & JAL premium passengers
Lounge ASO welcomes ANA and Japan Airlines premium passengers and eligible status holders, so it covers both Star Alliance and oneworld travellers flying from Kumamoto. Access follows your ticket and frequent-flyer tier rather than a dedicated airline lounge.
Star Alliance
oneworldWalk-in pay-in entry
If you hold neither an eligible card nor airline status, Lounge ASO is open to all passengers on a pay-in basis, so you can pay per visit at the door. It's the simplest fallback at a small airport where this is the only lounge.
Business-cabin passengers
KMJ has no separate airline or alliance lounge, so business-cabin passengers use the same Lounge ASO — typically as ANA or JAL premium passengers, via an eligible credit card, or by paying in at the door.
