Smart way to see Roppongi

Please the smart way to see Roppongi is not to go there at night, go during the day because when night comes the place turns into a sty.

How does it work though? Is there a barcode or some wireless thing in it? If I tap my LG against anything, nothing will happen.

Doesn't everyone already have a Navi app on their phone?

From the partially visible instructions, it looks like your phone has to have the Osaifu-Keitai e-wallel function. There is also a barcode visible. I doubt that it gives you anything that your smarthphone doesn't already have....

Probably you get the maps and ads of nearby izakaya & eating places & maybe shops and such. These establishments might be sponsoring this 'free' thingy.

Wow that's really cool.

Does it come complete with persistent Nigerian spam mail, to give you that authentic Roppongi experience, offering you entrance to exclusive clubs?

Is there a smart way to see Roppongi, besides from a distance?

wanderlust - lol!

does it comes in English too? but neat way to assist people out of town or tourists

Of course, coz they are actually charging (money not the battery) your phone LOL
