Domestic ~75–90 minutes when quiet; international ~2–2.5 hours; no sterile domestic↔international link.

Domestic cabin-bag passengers who already know the monorail/bus arrival can often work with about 75–90 minutes curb-to-gate when morning Haneda banks are calm. International check-in plus security and passport control still wants about 2–2.5 hours on a normal day — and more when typhoon recovery piles flights onto the first clear bank. Domestic↔international same-day connections are landside re-checks through the connector — they are not sterile airside transfers.

Connected campus since 2019, but domestic↔international still means landside re-clearance.

Since the 2019 integrated connector, Domestic and International share one passenger complex, but you still exit to landside flows to change between them. Monorail access is from the Domestic 2F passage. International check-in and Lounge RYURIN are on the international wing (3F / 4F). Always read the boarding-pass terminal/area line before you commit to a lounge or food stop.

Eat Okinawa specialties landside when you can; buy sealed water at konbini before screening.

Domestic landside and the upper restaurant decks carry the better everyday Okinawa set meals, taco rice, soba, and beni-imo sweets. Clear security with a konbini PET bottle already bought — airside mark-ups are real. After typhoons, the airport’s own notices have shown staggered food-outlet reopenings (e.g. November 2025 gradual F&B restart messaging) — do not assume every kitchen is live the morning after a closure.

Priority Pass does not cover OKA; LOUNGE HANA and airline rooms are the real options.

As of the live Priority Pass Japan lounge list (Sep 2026 check), Naha has no PP-contracted lounge. Use LOUNGE HANA on Domestic 4F if you hold an eligible Japanese gold card or will pay ¥1,320, or rely on ANA / JAL entitlement rooms airside domestic. International travellers without airline invitations should plan the gate area, not a soft-lounge meal.
