Starbucks used to have free WiFi but last time I was here they change the policy. I have to test it this time again.All those WiFi routers, non of it is free WiFi.Tokyo Metro Subway has WiFi but only available at stations.
Japan has a good cellular coverage and many WiFi signals but non of the WiFi Signal is FREE. I don't understand this. When you come to Japan, you need to ask your carrier how to get access in Japan.
