Japan eSIM & travel SIM plans
Filter by validity or data to find the plan that fits your trip.
Heading to Japan? An eSIM is the digital version of the prepaid travel SIM card — nothing to ship, nothing to swap. Buy before you fly, scan the QR code when you land, and you are online in minutes. Compare the plans below by validity and data.

What does unlimited mean?
Total: one allowance for the validity period. Daily: an allowance each day, continuation after use unconfirmed. Reduced speed: stays connected at a lower speed after the high-speed allowance. No throttling: explicitly no usage-based speed reduction. Fixed speed: a speed cap from the start. Policy unavailable: unlimited data confirmed, speed rules unknown. No throttling does not guarantee network speed.

Common questions about Japan eSIMs
Which networks will a Japan eSIM connect to?
Plans for Japan sold here connect to SoftBank / au (KDDI) / NTT docomo / Rakuten Mobile / KDDI/au / Telkomsel / XL / Smartfren / Indosat Ooredoo / m:tel / AXIS. Speed depends on the signal where you are standing and how busy the local cell is — who you buy from does not change it.
How much does a Japan eSIM cost?
There are 70 plans for Japan right now, priced from US$0.60 to US$79.99. Where you land depends on the data and validity you pick.
Are there unlimited plans for Japan?
Unlimited plans are available for Japan. Speed policies vary by plan: full speed, reduced speed after an allowance, or a fixed speed cap. Check the policy on each plan.
How many days can a Japan eSIM cover?
Anywhere from 1 to 180 days. Validity only starts once you arrive and the eSIM actually connects to a network, so installing before you fly costs you nothing.
