Cheap Japan eSIM plans
A low price only matters when a plan covers your trip and data needs.
The cheapest suitable plan must cover the entire trip and your estimated data use. These examples compare total converted prices, including unlimited offers when their verified allowances qualify. They assume no hotspot requirement.

What does “cheap” exclude?
A short-validity plan is excluded when it cannot cover your trip. Insufficient data, unverified prices and unknown unlimited rules also exclude a plan. We do not assume that buying repeated packages is supported, and do not include coupon codes or unverified checkout discounts.
Choose for your own trip
Light use assumes 0.5 GB/day, regular use 1 GB/day and heavy use 2 GB/day. Unlimited preference also checks a 2 GB/day high-speed estimate. Real usage varies; hotspot shares the data budget.
