There are several popular networks in Japan. The largest are SoftBank, AU and NTT Docomo, all of which have their own infrastructure. Of the three largest companies, NTT Docomo coverage is the most complete across the country.

Of the most frequented mountains for hikers in Japan, 63% receive reception at their rest huts with NTT Docomo. Compared to the 35% for AU and 14% for SoftBank, it is clear why more than half of people mountain climbing in Japan use Docomo and why 88% think the NTT Docomo network is the best.

This extensive Docomo coverage helps during the week when travelling around urban areas, but also means that those looking to travel to rural areas during their time off have the best chance of getting reception. For this reason Pripaid sim.com uses the NTT Docomo network, keeping users online across Japan.In addition to offering NTT Docomo SIM cards.

NTT Docomo coverage reaches even towering Mount Fuji, Japan’s tallest mountain. Soaring to over three thousand meters, it provides unparalleled views and has provided a majestic muse to countless Japanese artists. Climbing this mountain is a rite of passage for many, and is done by hundreds of thousands each year

Like most spots good for mountain climbing in Japan, Fuji is most accessible during the Summer season, but even then the extreme elevation means that the top will be extremely cold, so be sure to bring a good pair of shoes and wear sturdy, wind-resistant and above all warm clothing. The best views are seen at dawn, which means the path can become somewhat crowded during the nighttime and early hours, but it is well worth the lines for a chance to welcome a new day from the topmost peak of Japan.
