It doesn’t take long for visitors to Japan to realise that mobile phones are everywhere. Whether on the train, in cafés, or walking through the streets, you’ll see people messaging, streaming, or making calls. Japan has extensive network coverage, but for travellers, understanding phone options is important.
Mobile Phone Compatibility & Internet Access
Unlike in the past when Japan used a unique non-GSM system, modern 4G and 5G phones from most countries now work in Japan. However, roaming charges can be expensive, so it’s best to check with your provider before travelling. If you want a more cost-effective option, consider using an eSIM, a prepaid SIM, or renting a portable Wi-Fi device.

If you plan to use a pre-paid SIM card in Japan, make sure your phone is carrier unlocked before you travel. Some network providers lock phones to their service, which can prevent you from using a different SIM. Checking with your carrier in advance can save you the hassle of finding out your phone is locked after you arrive.
If you’re thinking about buying a phone in Japan, be aware that it’s difficult for foreigners, as most phone purchases require a long-term contract and a Japanese residence card. Without these, options are extremely limited, making it impractical for short-term visitors. Instead, renting a phone or using a pre-paid SIM or eSIM is a far easier solution.
Payphones in Japan
Despite Japan’s high mobile phone usage, public payphones are still fairly common, especially in train stations, airports, and convenience stores. They offer a reliable way to make local calls, and some can even be used for international calls.
Green & Grey Phones – Accept ¥10 and ¥100 coins, as well as prepaid phone cards.
Pink Phones – Coin-operated but only accept ¥10 coins.
Phone Cards – Available at convenience stores, newsstands, and kiosks in denominations starting at ¥1,000.
Local calls are affordable, typically costing ¥10 for the first three minutes and ¥10 per additional minute. Many payphones also feature animated LCD screens with friendly little characters, though instructions are often in Japanese.
While mobile phones dominate communication in Japan, payphones remain a useful backup, especially if your phone runs out of battery, or you need to make a quick call without using data.
