Tokyo eSIM: What to do the moment you land at HND
Your Tokyo eSIM starts counting the moment data roaming goes on for that line. Do that at Haneda, or over at Narita if the flight came in long-haul. Activation is first-usage, so installing the profile at home costs you no validity. Calls and texts continue on the home SIM, sitting beside the new data line.
13 plans for Japan, from 500 MB at $1.99 to 20 GB at $21.99, plus 6 unlimited-data tiers. 5 GB for 30 days costs $9.99 — 6th cheapest of 29 in Asia, against a $10.99 median. Our retail prices from the operator catalogue, checked 13 September 2026.

Landing at Haneda or Narita
One toggle and one APN field stand between you and working data in Tokyo. The profile attaches to Softbank or KDDI, and both are listed as 5G here. Android wants the access point name entered by hand, and the value is wbdata. The plan recharges online, and the balance holds with no expiry, checked 5 September 2026. Coverage runs the whole length of Japan, from Hokkaido right down to Okinawa. A Kyoto side trip or a night in Osaka rides on the same profile.
Which plan for Tokyo
For a fortnight around Tokyo, the workhorse plan is 5 GB over 30 days. It was priced at $9.99 when the Japan catalogue was checked on 5 September 2026. Japan's ladder runs to thirteen plans, and seven of them are fixed sizes. The smallest is 500 MB over 7 days, and the largest 20 GB over 30. Unlimited windows run the full length here, up to 30 days. They start at 3 days and step up through 5, 7, 10 and 15 days. Between the ends sit a 2 GB block over 15 days and a 3 GB block over 30.
No registration rule to clear in Japan
No registration step stands between a travel eSIM like this one and the Japanese networks. The Japan entry records no confirmed trap for a profile of this kind, checked 5 September 2026. There is no IMEI threshold to cross here and no passport to hand over. The only manual step in the whole process is that Android APN field. Type wbdata into that field, switch roaming on, and the profile handles the rest. That field is the first thing to look at when data refuses to start.
Top-ups and a balance that does not expire
More data is bought online, and the credit you add carries no expiry. That makes the first pick less final than a fixed day count suggests. Japan's ladder holds thirteen plans, opening at 500 MB over seven days. The 500 MB rung answers a stopover, and the largest block holds 20 GB. A recharge is an online purchase, so no counter in Tokyo is involved. The profile stays put on the phone while its balance changes, checked 5 September 2026.
Before you fly to Tokyo
- Haneda and Narita both hand the phone to Softbank or KDDI.
- wbdata goes into the Android APN field, and Japan lists no iPhone value.
- The Japanese ladder runs from 500 MB over seven days to 20 GB over thirty.
