The nearest airport is Komatsu Airport, but many visitors arrive by rail: the usual links are Hokuriku Shinkansen. Install your eSIM before leaving so you can check connections on the way.
Coverage is rarely the issue in the city itself; what matters more is having data as soon as you land, for transfers and maps.
Kanazawa is in the Chubu region. A single eSIM covers all of Japan, so there is no need for a local plan per city; what varies is how much data you use per day, which you can estimate below.
If you are travelling with several devices, look at the hotspot column before choosing: sharing one plan can be cheaper than buying two.
Before paying, check that your phone is unlocked and eSIM-compatible: the option usually sits under Mobile data or Cellular in the phone’s settings.
Pick your trip length and how you use your phone. The assumptions are visible and editable.
Buy the plan before you leave and keep the QR code or the app handy.
Install the eSIM at home on Wi-Fi. Most plans only start the validity period once the eSIM connects in Japan.
On landing, switch the eSIM on for mobile data and keep your home SIM for calls and texts if you need them.
Turn on data roaming for the eSIM line, then check that the phone shows a Japanese network.
Your phone must be carrier-unlocked and eSIM-compatible. Check this in your phone settings before you buy.
For a typical trip of 10 days with at least 5 GB, Saily ranks first at $10.99. The same eSIM works everywhere in Japan, not just in Kanazawa.
The nearest airport is Komatsu Airport. The usual onward links are Hokuriku Shinkansen.
No. Travel eSIMs for Japan are nationwide, so one plan covers every city and region on your route.
Install it at home on Wi-Fi a day or two before you fly, then switch it on for mobile data when you land. With most providers the validity only starts once the eSIM connects to a Japanese network.
A pocket Wi-Fi shares one connection with several devices but must be collected, charged and returned. An eSIM lives in your phone, so there is nothing to carry or give back.
It depends on the provider. The comparison table shows whether hotspot use is published as allowed, and some unlimited plans cap how much data you can share per day.
