Roaming in Japan: questions.

Roaming charges and rules for Japan, from the carriers’ own prices.

No. EU roaming rules apply in the EU, Iceland, Liechtenstein and Norway; Japan is outside them, so every carrier sets its own price. None of the 6 EU carriers we track include it in their EU allowance.

How we measured

The cheapest way to get 5 GB over 7 days at each carrier’s public prices, checked October 9, 2026. Prices in other currencies are converted at the ECB reference rates of October 8, 2026.
