Choosing an eSIM for Japan

These 228 plans use IIJ, KDDI, NTT docomo, Rakuten Mobile, and SoftBank. A plan on one network depends entirely on that network's signal; a plan that lists two or more connects to whichever has signal, which holds up better in Hokkaido, the Okinawa islands, the mountains or ski areas. See Japan's mobile networks compared for how they differ.

49 plans state that traffic exits in Japan, so your IP address is Japanese; 1 state an exit in Hong Kong. If you need sites or apps that only work from Japan, pick one marked Japan under “IP exit” in the plan details.

Another 178 don't state an exit.

If you're out every day using about the same amount, a daily plan fits; if some days you'll be on hotel Wi-Fi, a total-data plan usually works out better. To size it, start with how long 1 GB lasts.

Japan eSIM networks compared

Japan plans here use 5 local networks: SoftBank, KDDI, IIJ, NTT docomo, and Rakuten Mobile. Some plans stay on one network; others list several and connect to whichever has signal.

About eSIMs for Japan

Do I need a Japanese phone number?

Most travellers don't. WhatsApp and LINE keep working on your existing account for messages and calls. Whether a plan includes a local number or can receive texts is in its details.

What is the IP exit?

The country your traffic leaves from. Sites and apps use your IP to decide where you are: a plan that exits in Japan looks like a Japanese connection, while one that exits elsewhere may not open services limited to Japan.

Do I need data for Visit Japan Web on arrival?

Yes. At immigration and customs you open Visit Japan Web on your phone to show the QR code, so have the eSIM working before you land, or connect to airport Wi-Fi first.

Which operators will my phone use in Japan?

IIJ, KDDI, NTT docomo, Rakuten Mobile, SoftBank. Which one you connect to depends on local signal.

Where in Japan can I use it?

Anywhere the plan’s networks have signal, including Tokyo, Osaka, Kyoto, Okinawa; rural and mountain areas depend on local coverage.

Is 5G supported?

Yes. Operators here are listed with 5G; each plan's networks show which.

What happens when the data runs out?

It depends on the plan: some keep a usable speed of 1 Mbps / 5 Mbps; others drop to 128 Kbps / 200 Kbps / 256 Kbps / 384 Kbps / 512 Kbps, which is enough for messaging; others stop data.

When does the validity start?

It depends on the plan: first connection, installation or purchase. See Validity starts in the plan details.

Are there unlimited plans?

Yes. There's no total data cap; any speed limit shown on the plan still applies.

Can I use a hotspot to share data in Japan?

97 of these plans state personal hotspot support, so you can share data with a laptop or travel companions. It comes out of this eSIM’s allowance. Look for “Personal hotspot” in the plan details.

Can I install the same eSIM on a second phone?

No. Each QR code installs once. If you delete the eSIM or reset the phone, it can't be installed again, and once it has connected to a network it can't be refunded.

Can I top up data or extend validity?

Some plans add data, some add days, and some can't be topped up; each plan says which. Top up from the eSIM in My eSIMs. There's nothing new to install.

Are these prices tax inclusive?

Yes. The listed price is the final price.
