Worse than useless. Requires a Facebook or Google log in to function at all. – TRAVEL JAPAN Wi-Fi Review

Worse than useless—a scam. Basically puts you to work to sell yourself as a product to its advertisers and offers nothing in return. Just go to 7-11 for wifi. Requires users to authenticate through Facebook or Google to offer any service at all. No thank you. However this is a perfect example of the hoop-jumping, anti-consumer, creation-by-committee mindset that permeates Japan and in that sense should prepare you nicely for the frustrations that await.
