10 Common Questions Tourists Ask About Japan SIM Cards

Answers Every Traveler Needs Before Visiting Japan

If you’re heading to Japan and planning to stay connected, chances are you have questions about SIM cards. From compatibility to cost, setup to delivery—there’s a lot to consider.

Here are the 10 most frequently asked questions about Japan SIM cards, answered clearly and simply so you can travel with confidence.


❓ 1. Can I Use a Japan SIM Card in My Phone?

Yes, if your phone is unlocked. Most modern smartphones are compatible with Japanese networks, but your device must be unlocked from your home carrier.


❓ 2. How Much Data Do I Need?

It depends on your usage. For basic browsing, navigation, and messaging, 90GB (2 months) is usually enough. If you stream or work online, consider the 130GB (3-month) plan.


❓ 3. Is It Better to Get a SIM or Pocket WiFi?

For solo travelers, SIM cards are cheaper, easier, and more portable. Pocket WiFi is better for groups who want to share a single connection across devices.


❓ 4. Do I Need to Show My Passport or Register?

No. With OmoriWiFi SIM cards, there’s no ID, no registration, and no contract. Just insert the SIM and go.
