Know your IP before you pay
Every eSIM connects you in Japan, but plans differ on where your internet traffic exits, and that exit is the location websites see. Most providers hide it. We print it on every plan.
Websites and apps see you in Japan. The right pick for banking, streaming, and anything that checks your location.
Local networks in Japan
Your eSIM rides the same towers as a local SIM. These are the networks behind the Japan plans.

What to expect in Japan
A Japan eSIM from VoidMob rides KDDI (au) and SoftBank, the two carriers with the deepest 5G build-out across Tokyo, Osaka, and the Tokaido corridor, so you get fast data the moment you land at Narita, Haneda, or Kansai. There is no counter to find and no passport to hand over: scan the QR on the train into the city and you are online.
Routing is yours to choose. Pick a Japan-routed plan for a genuine local IP (useful for apps and sites that gate on a Japanese address) on 4G, or route via Singapore or Hong Kong for 5G speeds when raw throughput matters more than a domestic IP. Either way the plan covers the whole country, including rural Hokkaido and the Okinawa islands where coverage usually thins out.
