For business travellers bound for the Land of the Rising Sun and looking to keep roaming costs down, Vision Inc, providers of Global WiFi, the low-priced and high-network quality mobile Wi-Fi router rental service, has launched NINJA WiFi as a new service for foreign visitors to Japan. According to the Japan National Tourism Office (JNTO), foreign visitors to Japan in 2014 jumped 28 percent over a year ago to a record 13.41 million people, and many of these are corporate travellers. Yet many found finding a secure internet connection most difficult. Vision Inc capitalizes on its over one million Global WiFi users with the launch of a dedicated Japan service, allowing visitors to Japan to connect anywhere and any time they want. The new service takes its name from the spontaneity of the ancient ninja warriors, with rental routers easily booked online and picked up at airport counters in major Japanese destinations.  www.ninjawifi.com
