eSIM Tokyo

There’s no “Tokyo eSIM.” You need a Japan eSIM.

Let’s clear this up immediately: every eSIM that works in Tokyo works across all of Japan. There is no Tokyo-specific plan. What you’re looking for is the best Japan eSIM, and it will cover you from Shibuya to Sapporo.

Get an eSIM before you fly. It takes 5 minutes, costs less than a konbini onigiri, and saves you from hunting for SIM cards at Narita while jet-lagged.

What to get

Best overall? Get Ubigi. US$16.50 for 10 GB / 30 days. Best balance of price, reliability, and ease. Hotspot works. Top-ups are simple. This is the default answer for most travelers.

On a budget? Get Nomad. From US$4 for 1 GB. Cheap, straightforward, and you can add more data if you run out.

Want unlimited and don’t care about price? Get Holafly. Unlimited data, no top-ups, no math. About US$19 for 5 days. Good for heavy users, but hotspot is capped at 1 GB/day.

Need a Japanese phone number? Get Mobal. Most eSIMs are data-only. Mobal gives you a real Japanese number for bookings, verifications, and calls. From ¥990/month.

First time in Japan and want local support? Get Sakura Mobile. Japan-based company with local English support. Their unlimited 5G plans start at ¥5,000 for 7 days.
