The July 10 launch of Mount Fuji's free service coincides with the beginning of the mountain's climbing season and is expected to be warmly welcomed particularly by foreign visitors who are often surprised at the lack of free Wi-Fi hotspots in Japan. It's been made possible thanks to the efforts of one of the country's leading wireless carriers, NTT Docomo, which has partnered with several prefectural governments that administer walking trails up the 12,388-feet-high mountain.
