eSIM for Hokkaido
Sapporo has solid coverage. It is the long stretches between towns that catch people out, both for signal and for distance. Hokkaido is Japan's northernmost island, known for ski resorts, volcanic parks and open, quiet roads.

Hokkaido: what to know before you go
- Flying in
- Most arrivals land at New Chitose (CTS), close to Sapporo. Hakodate, Asahikawa and Kushiro have smaller airports, with long drives in between.
- Ski resorts
- The villages and lifts at Niseko, Furano and Rusutsu, the main resorts, are well covered. Off piste the signal fades and the risk goes up.
- On the road
- Many nationalities need an international driving permit to rent a car. Winter roads are tough going, so a live map and forecast really count.
- The parks
- Expect long signal gaps in Shiretoko, Daisetsuzan and Akan. Save maps offline and let someone know where you are heading.
How much data you need

Questions about Hokkaido
- Is there reception on the roads in Hokkaido?
- In towns and on the main roads, yes. It fades in the national parks and over mountain passes, so keep the full route offline.
- What is the cheapest Hokkaido eSIM plan?
- Hokkaido uses the Japan plans, because an eSIM belongs to a country and not to a city. $3.49 gets you 1 GB for 7 days. Data sizes range from 1 GB to 50 GB across 10 plans, and there are unlimited day passes too.
- Which mobile networks does the Hokkaido eSIM connect to?
- You get KDDI/au, NTT docomo, SoftBank, and Rakuten Mobile, on 5G wherever it is available. The operators are listed on every plan, so you can check before you buy.
- Is there an unlimited data plan for Japan?
- Yes, the day passes. Each day starts with a full speed allowance, and after it you stay online at a reduced speed of 1 Mbps.
- Will my phone number still work?
- Yes. Every plan is data only, so your regular line stays active for calls and texts, and WhatsApp carries on as usual.
- Should I buy a local SIM card in Hokkaido?
- There is no need. An eSIM is a digital SIM card that you install from a QR code before the trip, so you skip the airport kiosk and never open the SIM tray.
- How does it compare with roaming in Hokkaido?
- The eSIM is prepaid, so you know the full cost before you go and no charges appear later. Roaming is billed afterwards by your own carrier at its own rates, usually per day or per megabyte. Leave data roaming off on your regular line so it cannot bill you.
- When is the best time to install the eSIM?
- At home, on Wi-Fi, before you leave. Once you arrive, pick the Fizztrip line for mobile data and switch data roaming on for that line.
- When does the plan start counting days?
- At the first connection at your destination. Buying the eSIM or installing it does not start the clock, so a 30 day plan runs for 30 days from the moment it first joins a network there.
- Can I buy the eSIM weeks before my trip?
- Yes. Validity only starts at the first connection at your destination, so buying or installing early does not use up any days. Install it before the "Install by" date on your order.
- Is there a deadline to install the eSIM?
- Yes. Your order and the site show an "Install by" date, and an eSIM that is still not installed after that date expires. Buying early is fine: just install it on Wi-Fi before then.
- What happens when my data runs out?
- The connection pauses and nothing extra is charged, since every plan is prepaid. Top up from the eSIM page and you are back online on the same eSIM, with nothing to reinstall. On a day pass you get a full speed allowance each day. Once it is used, you stay connected at a lower speed (1 Mbps) until the next day begins.
- Can I add data later?
- Yes, straight from the eSIM page. The extra data goes onto the eSIM you already have, so there is nothing new to install.
- Can I share data with a hotspot?
- Yes. Hotspot traffic uses the same plan data and Fizztrip adds no fee for it. Keep in mind that a laptop burns through data much faster than a phone, so for remote work a day pass or a larger plan is the safer pick.
