Best eSIM for a Japan winter or ski trip

Winter in Japan means snow in Hokkaido and the Japanese Alps, hot springs, and city breaks in Tokyo, Kyoto and Osaka. An eSIM keeps maps, train apps and translation working from the moment you land, without a pocket Wi-Fi to collect or return.

Tips

Networks

Japan's main networks are NTT Docomo, KDDI (au), SoftBank and Rakuten Mobile. Travel eSIMs connect to one or more of them. Coverage is very good in cities and towns and along the main train lines.

Ski resorts and mountains

Resort towns such as Niseko and Hakuba usually have good signal. Higher up the slopes and in remote valleys it can drop, so download offline maps and share your location with your group before you go up.

Data only, usually no phone number

Most travel eSIMs for Japan are data only. That is fine for maps, messaging and calls through apps. Keep your home SIM switched on if you need SMS codes from your bank.

Cold weather and your battery

Phone batteries run down faster in the cold. Keep your phone in an inside pocket on the slopes and carry a small power bank.

Questions

Is an eSIM better than a pocket Wi-Fi in Japan?

For one or two people, an eSIM is usually cheaper and easier: nothing to collect, charge or return. A pocket Wi-Fi can make sense for a larger group sharing one connection.

Does my eSIM work on the Shinkansen?

Yes, mostly. There can be short gaps in tunnels, especially on mountain routes.

How much data do I need for Japan?

Maps, train apps, translation and messaging use about 1 GB a day. For 10 days, 10 GB or an unlimited pass is a common choice.
