AD PLACEMENT — CONTEXTUAL
If connecting from international to domestic, budget extra time for immigration and customs since Terminal 3 is fully separate.
Use the free inter-terminal shuttle bus rather than walking if you're moving between Terminal 3 and Terminals 1/2, as it's faster than it looks on a map.
JAL and ANA domestic-to-domestic connections within their respective terminals are the smoothest transfers at HND.
Watch the curfew — flights are restricted roughly 11pm to 6am, so late misconnections may mean an overnight wait.
Signage is excellent and bilingual, but plan for extra walking distance in Terminal 3's international departures area.

Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Terminals 1 and 2 are linked by a short indoor walkway (5-8 minutes), while Terminal 3 is connected to both via a free shuttle bus that takes about 10-15 minutes depending on traffic, or via the Tokyo Monorail/Keikyu line one stop away. International arrivals must clear immigration and customs in Terminal 3 before any onward domestic connection, effectively re-entering the sterile zone.
