Roaming vs eSIM in Japan: cost comparison

Roaming your home carrier in Japan costs significantly more than a local eSIM.

AT&T and Verizon international passes cost $10–12/day with hard data caps. Roaming overages can reach $10/MB on some plans.

US carriers like AT&T charge $12/day for limited daily data; after the cap, speeds drop to 128 Kbps β€” barely usable. Japanese tourist SIM cards from IIJmio (available at Bic Camera, Yodobashi Camera) cost $12–20 for 1 week. An LTE.app eSIM for Japan on NTT Docomo or SoftBank costs $8–15 for the same week β€” with faster setup and no physical card to manage.

Japan has some of the best urban LTE coverage in the world. NTT Docomo reaches over 99% of the population. Rural coverage is also strong in most regions, though deep mountain areas can have gaps.
