Why eSIM here, not a local SIM
Japan's local SIM market is famously hostile to short-term travelers — most kiosks require Alien Registration Cards, and tourist SIMs sold at airports come with high markup and time-limited validity.
Free Wi-Fi: Widely available. Free public Wi-Fi is widely available in stations, convenience stores, and tourist areas. eSIM gives you reliable coverage between hotspots.

Common questions about Japan
Will my eSIM work on the Shinkansen and in subways?
Yes, Japanese networks (NTT Docomo, SoftBank) maintain excellent coverage on major rail lines including Shinkansen and most Tokyo/Osaka subway tunnels. Expect 4G/5G for most of your journey.
When does my plan's validity start in Japan?
Validity starts when your eSIM first connects to a local Japan network, that's usually as soon as you land and switch off airplane mode. Installing the eSIM at home days before your trip doesn't burn any days.
Can I use my phone as a Wi-Fi hotspot in Japan?
Yes, all Esim70 plans support tethering by default with no separate daily cap. Your phone can share its data connection with a laptop, tablet, or travel companion's phone.
Will my home number still work in Japan?
Yes, modern phones support dual-SIM. Your home SIM stays active for calls and SMS while the Esim70 eSIM handles data abroad. You can keep WhatsApp / iMessage tied to your home number too.
