Avoid paying excessive roaming fees. Here we will tell you everything you need to know about roaming...
Roaming in Japan is available with most international carriers, but costs vary depending on whether you have inclusive roaming, a roaming pass or pay-as-you-go rates.
It’s typically one of the most expensive ways to stay connected, especially for data usage. More affordable options like eSIMs or prepaid SIM cards from BIC Camera, often available in vending machines, are usually a better choice for travelers.

Roaming lets you use your home mobile plan abroad by connecting to a local network in Japan. International carriers typically partner with major networks like NTT Docomo, SoftBank and KDDI, so service is available as soon as you arrive.
It’s not free in Japan for most travelers. Unlike within the EU, where roaming can be included at no extra cost, it usually involves either a daily roaming pass or pay-as-you-go rates.
Roaming is priced higher because your home provider adds extra fees for using partner networks abroad, often with separate rates for calls, texts and data.
Note: Before using roaming, make sure your phone works in Japan, since not all devices support the country’s network bands.
Roaming costs in Japan vary depending on your provider and plan. Most carriers offer daily roaming passes, while pay-as-you-go rates are significantly more expensive.

eSIMs are one of the easiest and most cost-effective options. You can purchase and activate them online before your trip, making them ideal for convenience and immediate connectivity upon arrival.
Japan SIM cards are widely available at airports, convenience stores and electronics shops. They’re usually cheaper than roaming, but require swapping your physical SIM and having an unlocked phone.
Pocket WiFi devices in Japan provide a portable hotspot you can share across multiple devices. They are a good option for groups or heavy users, though they require pickup, charging and return. You can typically pick them up at major airports like Haneda Airport and Narita International Airport.
Free WiFi is available in many public places like cafes, hotels and train stations. However, it can be unreliable or require sign-ups, making it less suitable as your primary connection.
