Japan is one of the most popular travel destinations in Asia and combines centuries-old traditions with modern technology. The country is known for historic temples, vibrant cities, and impressive natural landscapes. Famous attractions include Mount Fuji, the historic temples of Kyoto, and major cities such as Tokyo and Osaka. Many travelers visit Japan for its culture, cuisine, modern cities, and the unique blend of tradition and innovation.

Japan has one of the most advanced mobile network infrastructures in the world. The main network operators are NTT Docomo, SoftBank, and KDDI (au). In major cities, along major rail routes, and in most tourist areas, visitors can generally expect excellent 4G coverage and widely available 5G networks. Mobile internet is also widely available in many rural areas thanks to Japan’s dense network infrastructure. However, coverage may be limited in remote mountain regions or on smaller islands. Using an eSIM with a dedicated data plan for Japan is therefore important for travelers to stay connected during their trip.
