Japan eSIM Price Comparison — manaMOBILE vs Airalo vs Holafly
eSIM prices vary wildly. A 5GB Japan plan can cost $9 or $27 — more than 3x difference for the same data. We broke down every plan tier across the top four providers so you can see exactly what you're paying per gigabyte.
Price Per GB — 3GB Plan (Most Popular)
| Provider | Total Price | Price / GB | Carrier |
|---|---|---|---|
| manaMOBILE | $12.00 | $4.00 | Docomo + SoftBank |
| Airalo | $12.50 | $4.17 | SoftBank |
| Ubigi | $15.00 | $5.00 | Docomo |
| Holafly | $19.00 | $6.33 | KDDI |
All Plan Tiers Compared
| Provider | 1GB | 3GB | 5GB | 10GB |
|---|---|---|---|---|
| manaMOBILE | $10.00 | $12.00 | $24.00 | $28.00 |
| Airalo | $4.50 | $12.50 | $20.00 | $32.00 |
| Holafly | — | $19.00 | $27.00 | $44.00 |
| Ubigi | $8.00 | $15.00 | $24.00 | $40.00 |
Airalo wins at 1GB. At 3GB (the sweet spot for 7-10 day trips), manaMOBILE is cheapest. At 5GB+ manaMOBILE stays competitive. Holafly's "unlimited" plans sound appealing but throttle to 500kbps after 500MB/day — effectively making them limited, and expensive per unthrottled GB.
Hidden Costs to Watch For
- Top-up pricing — Some providers charge more for top-ups than initial purchase. manaMOBILE keeps the same per-GB rate.
- Short-expiry penalties — 7-day plans that expire before your trip ends force a second purchase. manaMOBILE offers 30-day plans across all data tiers.
- Carrier lock — Single-carrier eSIMs drop in rural areas. Dual-carrier (manaMOBILE) means fewer dead zones.
Bottom Line
For 3GB+ trips, manaMOBILE wins on price, carrier coverage, and activation simplicity. Budget travelers on 1GB can save $5.50 with Airalo — but the single-carrier limitation is a real trade-off in rural Japan.
