If you’re planning a trip to Japan, staying connected is essential. Whether you’re navigating the Tokyo Metro, translating a drink menu, or trying to find the hidden entrance to a rooftop bar in Shibuya, mobile data is your lifeline. That’s why more and more travelers are skipping the SIM card vending machines and choosing an eSIM for Japan instead — and one of the best options on the market right now is Saily.

What Is an eSIM and Why Use One in Japan?
An eSIM is a digital SIM that lets you activate a cellular plan without inserting a physical card. That means no more searching for SIM shops at Narita or dealing with language barriers at electronics stores.
With an eSIM like Saily, you can activate your mobile plan before you even land — so your phone connects the moment you touch down at Haneda or Kansai Airport.
