Good to know in Japan
Install the eSIM before leaving airport Wi-Fi and keep data roaming enabled for the travel line. Japan's dense rail network includes tunnels and underground sections, so a brief hand-off or signal drop does not necessarily mean the plan failed.

Plans start at $0.50 and the median price is $1.19/GB. For a 15-day trip, the cheapest works out to about $0.03 per travel day. Prices re-checked 21 min ago.
When should I install an eSIM for Japan?
Install on reliable Wi-Fi within the provider's documented window. Some plans start validity at installation and others at first connection, so follow the selected plan's email rather than assuming.
Are unlimited eSIM plans available for Japan?
Yes. 276 current plans are listed as unlimited. Read each network note for a daily high-speed allowance or throttle rule; “unlimited” is not automatically full speed all day.
Can I use hotspot with an eSIM for Japan?
