Choosing an eSIM for Japan
A Japan eSIM provides mobile data on a compatible, unlocked phone without a physical SIM change. Compare the current plans above by allowance, validity and network, including truly unlimited plans with no data limit and no throttling.
Networks and coverage
Current Japan plans list 5G through NTT docomo, Rakuten Mobile, KDDI/au, and SoftBank. Network generation and availability depend on the selected plan, device compatibility and local coverage.
How much data to choose
Available allowances include 1GB, 3GB, 5GB, 10GB, 20GB, and 50GB. Truly unlimited plans have no data limit, no daily cap and no throttling. Other plans labelled unlimited include a daily data allowance, and speed is reduced to about 256 kbps after the daily limit. Options currently cover 1- to 30-day validity. Match validity to the complete trip, then choose data based on navigation, messaging, work and streaming needs.
Trips often link Tokyo, Kyoto and Osaka by train, with maps, translation, train and restaurant bookings and photo sharing in constant use. If you will rely on your phone all day, a truly unlimited plan means you never have to watch your data; otherwise choose a fixed allowance and a validity that covers every travel day.
Local SIM or travel eSIM?
A travel eSIM can be installed before you leave and keeps your own SIM available for calls and texts, as long as your phone is unlocked and supports eSIM. The truly unlimited plans connect directly to KDDI in Japan rather than roaming on a foreign network, so they behave like a local line.
Japan eSIM questions
For the truly unlimited plans, which connect directly to KDDI's network in Japan instead of roaming on another operator, keep data roaming off for the eSIM line. Because the connection is local, response times are generally lower than on eSIMs that route your data through another country. For other plans, follow the setup instructions sent with your eSIM.
Current Japan plans range from $1.80 to $68.79, depending on data allowance and validity. Compare the total data and number of days as well as price, because the cheapest plan may not cover the whole trip.
Truly unlimited plans have no data limit, no daily cap and no throttling. Other plans labelled unlimited include a daily data allowance, and speed is reduced to about 256 kbps after the daily limit. The plan label and the details on each plan card show which kind you are buying.
The validity period begins when the eSIM first connects to a supported mobile network in its coverage area. You can install it before departure and connect when you arrive.
Hotspot availability depends on the phone, selected plan and network policy. Top-up availability is checked for the specific eSIM after purchase; when compatible top-ups exist, Yatelo displays them in the eSIM account controls.
