Be in Japan in a few days.. – Japan Connected Wi-Fi Review

I'll be in Japan in a few days so I have my hopes up for this app since public wifi was so confusing to use over there. I did pick up a lot of seemingly public wifi signals but they all sent me to some kind of authentication page...which was so confusing and I have not succeeded to actually get on to internet. One exception was FamilyMart wifi but they had some restriction like you can't be on it for more than 10min or no more than 1hr per day or something like that. Not being in Japan yet all I could do was to check on map from this app to see wifi spots: it seems like there are plenty of wifi at random places almost everywhere in Japan. I believe the easiest spot to find wifi hotspot with this app is any major public facility like train stations(that you'll find every 2miles all over any major metropolitan areas of Japan. I'll update my review while I'm there. Just one concern: what if there's an update for the app that require me to be on the net, BUT if I can't get on the net BECAUSE I haven't updated the app? That kind of catch22 situation is so classic I'm afraid I'll experience with this app? 一つ心配なのが、アップデートしなければネットに繋がらず、アップデートしていない為にネット繋げられないという「三すくみ」状態となる事です。
