Where you will use it
Around Osaka
Full coverage in Namba, Umeda, Shinsekai, Osaka Castle, Universal City on every plan.
- Buy an ICOCA card for the trains or add it to your phone wallet; it also works in Kyoto and Kobe.
- The Universal Studios app and timed tickets need data on the day; download it the night before.
- Dotonbori and Namba are crowded on weekend evenings and the network slows a little; 5G plans cope better.

Osaka eSIM questions
How much does an eSIM for Osaka cost?
Plans start at $1.10 for 500 MB · 7 days. Unlimited daily data costs $1.38 a day (the first 500 MB each day at high speed, then 384 Kbps under the fair use policy). Prices are in US dollars and include everything: no roaming fees, no subscription.
Which airport should I plan for, Kansai or Itami?
International flights land at Kansai (KIX); Itami is domestic. Both have full coverage on every operator and trains into the city, so the eSIM works from the gate at either.
Is one eSIM enough for Osaka, Kyoto and Nara?
Yes. All three are in Kansai, 30 to 60 minutes apart by train, and a Japan plan covers them all with no change of settings.
