Haneda arrivals
Haneda's advantage is speed, and many of its flights land after the counters close. This is the airport a pre-installed eSIM was made for.
Desks keep hours; your flight does not. A plan installed at home works at any hour: airplane mode off, three switches, online before the taxi rank.
Order online, scan the QR on Wi-Fi before flying. After landing: line on, set as data, roaming on for it. 10GB for a week runs $12.44 and a short hop does fine on 3GB for 3 days at $7.06, the live catalog checked October 22, 2026.
HANEDA-FREE-WIFI covers the terminals. Buy on the site over it, the QR arrives by email in minutes, and you can be installed before your bag appears. A fine plan B, a needless plan A.
Which stop, which transfer, which exit: late at night with a suitcase is not the time to guess. Get data working in arrivals and load the route while you walk.
Stay on the Wi-Fi and run the rescue card: airplane toggle ten seconds, data line, roaming on for the travel line, one restart. Still dark: the chat bubble reaches a human; send your order number and terminal.
Arrival desks exist but keep hours, and late flights miss them. Any online eSIM can be bought and installed over the free HANEDA-FREE-WIFI network, or better, installed at home before the flight.
Yes, HANEDA-FREE-WIFI across the terminals, enough to buy and install an eSIM on the spot.
Installed beforehand, about a minute after airplane mode goes off: turn the line on, set it as data, enable roaming for it, and KDDI picks it up.
