Seamless Coverage with Top Carriers

Japan offers exceptionally robust mobile network coverage across its four major carriers: NTT Docomo, au (KDDI), SoftBank, and Rakuten Mobile. Tourists can expect extensive 4G LTE availability nationwide, even in many rural and mountainous regions, ensuring reliable communication. 5G network expansion is rapidly progressing, primarily concentrated in urban centers and key transportation hubs. Both physical SIM cards and eSIMs leverage these advanced networks, providing comparable high-speed data and voice services, making it easy for tourists to stay connected throughout their journey. For instance, Prune offers eSIM solutions that utilize these same reliable networks, ensuring seamless connectivity.

Metro & Transit Coverage

Japan's major metropolitan areas, including bustling Tokyo and vibrant Osaka, boast outstanding 5G and 4G/LTE mobile network coverage. Connectivity is not limited to above-ground areas; tourists can expect seamless high-speed internet access within extensive subway systems, underground shopping complexes, and even on the high-speed Shinkansen bullet trains. This widespread and reliable network infrastructure ensures that visitors can navigate, communicate, and share their experiences without interruption, even while traveling through dense urban environments or underground transit routes.

Currency

The official currency of Japan is the Japanese Yen (¥, JPY). It is available in various denominations of coins (1, 5, 10, 50, 100, 500 yen) and banknotes (1,000, 2,000 (rare), 5,000, 10,000 yen). While credit card usage has increased, Japan remains a predominantly cash-based society, especially in smaller shops, traditional restaurants, vending machines, and rural areas. It's advisable to always carry a sufficient amount of cash for daily expenses. ATMs that accept international cards are widely available, particularly at post offices and 7-Eleven convenience stores, which are ubiquitous.

Credit cards

While Japan is known for its cash culture, credit card acceptance has significantly expanded, especially in major cities, large department stores, chain hotels, and prominent restaurants. Visa and Mastercard are the most widely accepted cards, followed by JCB and American Express. However, smaller shops, local eateries, traditional inns (ryokan), and establishments in more rural areas often operate on a cash-only basis. It's prudent to confirm payment options in advance, especially for smaller businesses, and always carry some Japanese Yen to cover situations where cards are not accepted or for smaller purchases.

Local language(s)

The official and primary language spoken throughout Japan is Japanese. While English is taught in schools, proficiency among the general population varies, with higher levels of English spoken in major tourist centers, international hotels, and at large transportation hubs. Learning a few basic Japanese phrases, such as 'Arigato' (thank you), 'Sumimasen' (excuse me/sorry), and 'Konnichiwa' (hello), can greatly enhance your travel experience and is often appreciated by locals. Many signs in major cities and tourist attractions also include English translations. Utilizing translation apps or portable Wi-Fi devices can be very helpful for communication.
