Can I use one eSIM for both the Sapporo Snow Festival and multiple ski resorts?

Yes. A single Japan travel eSIM with sufficient data and duration will cover both the Sapporo Snow Festival and your time at ski resorts like Niseko, Furano, Teine, or Kiroro. As long as your plan is valid for the length of your trip and offers coverage on major Japanese networks, you can move freely between cities and mountains without changing SIMs. Just monitor your data usage if you’re frequently using navigation, social media, and video calls, and consider choosing a slightly larger data package if you plan to stay 10–14 days or more.
