Vodafone roaming in Japan: what it costs
Japan sits in Vodafone's Zone 6, with a daily pass of 3 € a day that includes 1 GB every 24 hours and renews itself. It's one of the most reasonable roaming rates on the Spanish market: fourteen days with data come to 42 €. A local eSIM for the same trip costs 4,90 € with 3 GB.

Three euros a day sounds like nothing. And it is, compared with what others charge. The sum worth doing isn't the daily one: it's multiplying by the days you'll be there, which is the one nobody does when they look at the rate.
The number
| Item | Detail |
|---|---|
| Plan | Bono Diario Zona 6 |

Check your specific plan in Mi Vodafone before you fly: conditions depend on your contract and change over time.
What the whole trip comes to
| Duration | Vodafone daily pass | Zas eSIM |
|---|---|---|
| 7 days | 21 € · 1 GB a day | 2,90 € · 1 GB |
| 14 days | 42 € · 1 GB a day | 4,90 € · 3 GB |
| 30 days | 90 € · 1 GB a day | 5,90 € · 5 GB |
The pass gives you 14 GB over two weeks and the eSIM gives you 3. If you're genuinely going to use fourteen gigabytes, the pass is a sensible choice and we won't pretend otherwise. If you're going to use three, which is the norm in Japan because video waits for the hotel Wi-Fi, you're paying 42 € for 4,90 € worth of data.
When the pass is the right call
- A short trip of two or three days: for six euros it's not worth arranging anything else.
- You need your Spanish number with data, no second line.
- Your phone doesn't support eSIM.
- You'll use a lot every day: work video calls or sharing data with other people.
Does the Vodafone pass activate by itself?
Yes, it activates when you use data in the zone and renews automatically every 24 hours for as long as you keep browsing. That's convenient, and it's also why the bill grows without you noticing.
What happens if I use up the day's gigabyte?
It depends on your plan's conditions: the speed may drop or the excess may be billed separately. That's in your contract, not on this page; check Mi Vodafone before you travel.
Does the same pass work in Thailand or Vietnam?
Yes, all three are in its Zone 6 according to its website on 22 August 2026, along with Mexico, Canada and several more countries. Confirm it for your specific route before you leave.
