Easy and Cheap Mobile Data in Japan

The large selection of data package sizes gives you plenty of options and the opportunity of finding just the right eSIM for your needs.

Cheaper than Physical Prepaid SIM Cards

Although Japan is often portrayed as a high-tech country, mobile telephony, and especially mobile data, is actually quite expensive. A popular provider of physical prepaid cards (SIM cards) is the local company Mobal.

Mobal offers several different prepaid SIM cards targeted at tourists. Below, I have compared two of their popular prepaid cards. The comparison clearly show that eSIMs from JetPac is the cheapest option for data roaming in Japan.

The prices are found on Mobal’s website and are very similar across competing prepaid SIM-card providers.

Comparison with Local Prepaid Card

The prepaid SIM cards from Modal starts at ¥4,730 (€26.01/ $30.58) for which you get 25 GB of data and a validity of 8 days. In comparison, the JetPac eSIM starts at just €0.85 ($1) for 1 GB of data and 7 days validity.

If you need more data and a longer duration, JetPac offers eSIM of up to 50 GB. The largest eSIM with 50 GB of data and validity of 30 days cost only €25.52 ($26). This is around half the price compared to the largest prepaid SIM card from Modal. Their largest eSIM comes with 50 GB and a validity of 31 days but for a price price of ¥7,920 (€43.55/ $51.20).

If you need more during your trip, you can ‘top-up’ with more data via the JetPac’s app.
