These are examples from the available Japan listings, rather than a single fixed price. An unlimited option can be convenient for heavy use, but it costs more than a limited-data option in the examples above, so choose it only when that flexibility matters to you.
How to choose a plan
Choose a smaller data allowance if you mainly need maps, messages, travel information, and occasional browsing.
Choose a larger allowance if you expect to share photos, watch media, or use your phone throughout the day, because frequent use can consume data more quickly.
Match the validity period to your stay, because a plan that ends before your departure may require another purchase.
Compare the total price as well as the data allowance, so the plan fits both your usage and your travel budget.
