If you have never been to this, it’s worth to watch once. This is very much the tourist spot but even myself as Japanese, I am glad I saw this once. You go in there and totally sees the difference culture, different world, different vision. I don’t even think it’s so Japanese but it’s an entertainment. Don’t go there to eat something. Eat before but go out for food after. You can just have a drink and enjoy the show. Sorry, I don’t even know how to describe this but mix of robot and people are acting and dancing with the music to create this weird culture. It nothing like Disneyland’s show or anything you have seen in the musical. You can get the ticket thru online or I actually bought a ticket at Harajuku information center.
