日本 eSIM
Japan is the destination Thai travellers buy eSIMs for most, because almost every part of the trip runs on a phone: planning transfers between train lines, checking timetables that shift by the minute, booking restaurants that only take reservations in an app, and finishing arrival paperwork before you land. Urban coverage is dense and reaches most subway platforms, so the practical question is not whether you will have signal but how much data your days actually consume and when you switch the line on.
This page carries 91 eSIM plans for Japan, riding on NTT DOCOMO / KDDI (au) / SoftBank with 3G / 4G / 5G support. Install the profile at home before you fly; the plan starts counting when the phone first registers on a network at the destination.

How much data you actually need
A typical Japan trip uses about 800MB–1.5GB a day because maps and train apps stay open from morning to night. If you upload video every evening, budget around 2GB a day, and if you tether for travel companions, multiply by the number of devices that lean on your line.
When you land
Main gateways are Narita (NRT), Haneda (HND), Kansai (KIX), Chubu (NGO) and Fukuoka (FUK). Turn the eSIM line on as soon as you land — you normally have service before immigration, which helps if you still need Visit Japan Web, and it means you can plan the train into the city without hunting for airport Wi-Fi.
Where coverage changes
Signal is strong across Tokyo, Osaka and Kyoto including underground. Mountain areas — hiking routes in the Japanese Alps, Shirakawa-go in snow season, and stretches of rural Hokkaido lines — can drop in and out, so download the map area before you leave the last big town.
Cities travellers ask about
- Tokyo — City-wide coverage including subway stations and platforms.
- Osaka — Heavy map use around Namba and Umeda, where stations have many exits.
- Kyoto — A bus-based city; you will check live departure times all day.
- Hokkaido — Thin patches between towns; download maps ahead of the drive.
- Okinawa — Beaches and outer islands vary from spot to spot.
Read it city by city: Tokyo, Osaka, Kyoto, Sapporo, Fukuoka, Nagoya, Hiroshima, Nara, Okinawa
Apps to install before you fly
- Google Maps or Yahoo! Norikae for train transfers
- Visit Japan Web for immigration steps
- Tabelog or Google for restaurant bookings

常見問題
Does an eSIM work on the Shinkansen?+
Yes, though long tunnels interrupt it, especially on the stretches that cut straight through mountains. If you need to join an online meeting on board, download the files you need beforehand and leave slack in the schedule; service comes back on its own once the train clears the tunnel or stops at a station.
Do I need an unlimited plan for Japan?+
Usually not. A 10–20GB plan covers a typical 7–10 day trip built around maps, chat and photos. Unlimited pays off when you stream or go live every day, or when you tether several devices off one line. Multiply your realistic daily use by the number of nights before you decide.
Should I turn roaming off on my Thai SIM while using the eSIM?+
Yes. Set the eSIM as the data line and switch data roaming off on your Thai SIM so you are not billed twice without noticing. You can still leave the Thai line registered for calls and SMS if you are waiting on bank one-time passwords, because receiving a text does not draw on the eSIM data allowance.
When does a Japan eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
