Prepaid sim card in Japan

In this page, we carefully select Japanese providers of prepaid SIM card enabling you to find out the best one for your Japan travel style.

Some might think free WiFi spots, which are increasing in Japan, are just fine for your needs.
However, free WiFi spots will not satisfy your needs completely as they have several weak points such as limitation of place/time, hassle of personal authentication, and low security level.

And, this is a turn of prepaid SIM cards, which clear such issues.
However, while suppliers selling prepaid SIM cards are rapidly increasing in Japan, some of them display wrong information due to a shortage of knowledge of prepaid SIM card and the networks in Japan.

In this page, we list only providers selling high-quality prepaid SIM cards offered by reliable manufacturers or authorized dealers.

Some might think international roaming is just fine for your needs.
However, we have heard that some travelers ended up their travel with high roaming charges.
Who can say your roaming is definitely okay or has confidence to avoid unreliable internet connections overseas completely?
Before you read the complicated agreements on roaming thoroughly, we recommend that you just purchase a prepaid SIM card.

And, buying a prepaid SIM card is the most reasonable way to use the internet in Japan.
It is more cost effective than renting a pocket WiFi router.

Thank you for reading through.
Lastly, to confirm a prepaid SIM card working properly with your device, you may check the followings before buying.
1. Frequency compatibility between your device and Japan.
2. SIM lock on your device: unlocked or not.
3. Carrier lock: unlocked or not.

In this list, we research prices and services of the providers periodically to ensure that you can securely purchase prepaid SIM cards.
It would be greatly appreciated that you give me the latest information if you notice our information is outdated even slightly. We will then update it soon accordingly.
