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.

Good questions about Japan eSIMs
What is the cheapest eSIM for Japan?

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. 355 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.
