Japan eSIM prices
Data plans start at $2.99 for 1 GB valid 7 days, and unlimited plans start at $16.99 for 3 days. Everything is prepaid, data-only and bought in the app: no contract, no deposit, no daily rental fee.
Data plans
Match the bundle to the trip. Validity begins the first time the eSIM connects to a network in Japan, not on the day you pay for it.
| Data | Validity | Price | Price per GB |
|---|---|---|---|
| 1 GB | 7 days | $2.99 | $2.99/GB |
| 3 GB | 30 days | $5.99 | $2.00/GB |
| 5 GB | 30 days | $8.99 | $1.80/GB |
| 10 GB | 30 days | $15.99 | $1.60/GB |
| 20 GB | 30 days | $27.99 | $1.40/GB |
| 50 GB | 30 days | $55.99 | $1.12/GB Best value |
Unlimited plans
Unlimited plans have no total cap. After 3 GB at full speed in a single day the speed drops for the rest of that day and comes back the next morning — the same fair-use arrangement carriers apply to their own unlimited plans.
| Validity | Price |
|---|---|
| 3 days | $16.99 |
| 5 days | $23.99 |
| 7 days | $31.99 |
| 10 days | $47.99 |
| 15 days | $70.99 |
| 30 days | $129.99 |

This page covers Japan. The same app sells plans for more than 200 other destinations, which helps when Japan is one stop on a longer route, or when the trip continues to South Korea or Taiwan.
What every plan includes
5G and LTE on Japan's networks — in the cities, along the rail corridors and in most towns.
Hotspot and tethering, included rather than sold as an add-on.
Top-ups that land on the eSIM already in the phone — no second install.
Your own SIM stays in the phone for your number, calls and SMS codes. The plan adds no Japanese number.
Pricing questions
How much does an eSIM for Japan cost?
Plans start at $2.99 for 1 GB valid 7 days. A week of maps, transit apps and a few uploads, with hotel Wi-Fi at night, usually lands around $8.99. Unlimited plans start at $16.99.
Is an eSIM cheaper than roaming in Japan?
For almost anyone, yes, and often by a wide margin. Japan sits outside every roam-like-at-home zone, so your carrier bills it at its out-of-region rate — for many European and American operators the most expensive line on the tariff sheet. Look yours up before you fly and put it next to a plan here: a larger bundle is $15.99 for 30 days, paid once. It usually undercuts pocket wifi too, because pocket wifi is priced by the day and this is priced once.
Are there hidden fees?
No. The price on the screen is the whole price: no activation fee, no deposit, no daily rental building up, no monthly charge, and no automatic renewal. The app is free, and plans simply expire.
Which plan should I choose?
A city break with hotel Wi-Fi at night is mostly maps, transit apps and photos going out, and does not need much. Take a larger bundle if you work from the phone, share a hotspot with the family, or navigate and translate your way through a full itinerary every day. Take an unlimited plan if you would rather not think about it.
