Check price
How I check these prices: every plan above is repriced from the live rate sheet each month, stamped with the date, and compared against Airalo, Holafly, Nomad, Saily and Ubigi in the cross-brand price test. My full method is on the about page.
How much data do you need in Japan?
My rule from years of watching my own usage: maps, messaging and browsing burn about 500 MB a day, and social video pushes it toward 1 GB. Matched to the actual plans above:
| Trip | Typical use | Buy this | Price |
|---|---|---|---|
| Weekend, maps and messages | about 500 MB/day | 3 GB · 90 days | $5.86 |
| One week, normal tourist use | about 700 MB/day | 5 GB · 90 days | $6.98 |
| Two weeks, normal tourist use | about 700 MB/day | 10 GB · 90 days | $9.53 |
| Work trip with hotspot | 2 GB+/day | 15 GB · 90 days | $12.72 |
Why I recommend the Fizen 50 GB plan
For Japan, the Fizen 50 GB plan at $18.46 is the value pick for a normal trip. If you just need maps and messaging, the 3 GB at $5.86 is enough; for a longer stay the Unlimited/day stretches further. I recheck these prices against Airalo, Holafly and the other big brands every month.
For most trips to Japan the Fizen 50 GB plan is the one I would buy again, at $18.46 for 90 days on the SoftBank line. If your trip is shorter or longer, size up or down from the table above.
Airalo vs Holafly vs Nomad in Japan: the same plan, priced

Six stores, one allowance: 50 GB with 90 days of validity, priced the same week at Airalo, Holafly, Nomad, Saily, Ubigi and Fizen. This month Fizen has the lowest price for Japan, 74% under the next best, which is why it is the plan I buy here.

Competitor prices come from their public stores for the closest matching plan and are rechecked monthly. They sell in different bundle sizes, so I compare on price per GB for the allowance shown. See the full cross-brand price test →

Japan eSIM questions
What is the cheapest eSIM for Japan?
For a 50 GB plan with 90 days of validity, the cheapest price this month is Fizen at $18.46. Airalo, Holafly, Nomad, Saily and Ubigi all price the same allowance higher; the comparison table on this page has the exact numbers. Prices move, so check the date stamp next to the table.
Is Airalo or Holafly cheaper for Japan?
Airalo is the cheaper of the two here: Airalo charges about $87.90 for a 50 GB-class plan while Holafly, which only sells unlimited, runs $287.50 for the same 90 days. For Japan, Fizen undercuts both at $18.46.
Will an eSIM work in Japan?
Yes, if your phone is eSIM capable and carrier unlocked. You install the plan by QR code before you fly and it connects when you arrive in Japan. Your home number stays on your normal SIM.
Which networks does a Japan eSIM use?
Plans on this page ride on IIJ, SoftBank where named, and the rest use multi-network eSIMs that attach to the strongest partner carrier in Japan. The network column in the table shows which line each plan uses.
Are there hidden costs or fees?
Nothing hidden on the price, and there is no activation fee. Two things to check before buying: validity starts when you activate, not when you pay, and after the high-speed allowance most plans here slow down instead of cutting off (between 128 kbps and 10 Mbps depending on the plan; the exact speed is printed on each row of the table).
What is the difference between a day pass and a data pack?
A day pass gives you an allowance every day (like 1 GB per day) for the number of days you choose, which suits daily heavy use. A data pack is a fixed pool (like 10 GB) you use across a validity window. Both are in the table above so you can pick what fits.
How much data do I need for Japan?
For maps, messaging and the odd video call I plan on about 3 to 5 GB a week. Stream or tether a laptop and 10 GB is safer. Match the tier to your trip length in the table.
When does validity start, and can I tether?
Validity counts from activation, not purchase, so install early and turn it on when you land in Japan. Tethering works on these plans; a hotspot burns data fast, so size up if a laptop will lean on it.
