Quick answer: Pocket WiFi makes sense if you are travelling as a group or family. One device connects up to five phones and needs no setup. Travelling solo with a recent phone? An eSIM is usually cheaper, with nothing to collect or return. Either way, do not count on free public WiFi in Japan: coverage is patchy and many networks make you register through an app or web form first.

Where does eSIM fit in? The table above was written before eSIM became standard on most phones. If your handset supports one, an eSIM is activated by scanning a QR code before you fly, with nothing to collect at the airport and nothing to return. The trade-off is that it covers one phone only, so a family or group still comes out cheaper sharing a single pocket WiFi unit. Compare Japan eSIM options on Klook →
So which eSIM should you buy? The Klook listing above is a marketplace, with many plans from many resellers, starting at US$0.85 and delivered as a QR code within minutes. Sakura Mobile is a Japanese carrier selling direct: its travel eSIM starts at ¥1,500 (¥1,650 with tax) for unlimited data on stays of up to 90 days.
The honest difference is not really the price, it is how much you have to work out for yourself. That US$0.85 is the cheapest entry option, not the plan you will actually need, and you are choosing between resellers you have never heard of. Sakura Mobile costs more at the door but states the number before you commit and handles technical support in English. It also sells physical SIM cards (from ¥3,500) and pocket WiFi (from ¥299 a day) with pickup at airports, hotels or your accommodation. That is the option that matters if your phone will not take an eSIM at all. If you only need maps and messaging for a few days, buy the cheap one. If you would rather not spend your first evening in Japan debugging an APN setting, pay the difference. (Prices checked August 2026.) See Sakura Mobile's travel plans →
