STEP 2 · COMPARE
Same data.
Same data.
Clearer trade-offs.
For a useful like-for-like comparison, this table uses each provider’s current Japan 10GB plan.
Prices checked August 28, 2026 in USD. Sale pricing and plan details can change. Network, 5G, FUP and hotspot conditions should be reconfirmed on the provider page before purchase.
Price matters.
Fit matters more.
Fixed or unlimited?
“Unlimited” plans may have fair-use conditions. Read the exact plan terms before relying on hotspot or video use.
Japan or multi-country?
A regional plan can be simpler across borders, but compare its country list and price with a Japan-only plan.
