Super cool place to see a next level arcade gaming and amusement park hyrbrid
If you're into seeing the next level of arcade games this is where to go, more so than Akihabara these days. Don't worry about English translation, they give out a pamphlet that say which activities require extensive Japanese and that was only about 7 of the 25ish they had available (none of them mainstream ones). My highlights were the games that could rotate physically in almost any direction, as well as the thrill ride and gaming hybrids. Also included was a no latency VR game, mystery games, simulated fantasy coasters and many more. Spent nearly 4 hours here and kind of wish it was the whole day.
Lots of fun, if you are willing to queue
Yes there some good rides/ games in there, however, like everything popular in Tokyo - there are QUEUES! (upto 60 minutes sometimes, and this ain't even Disneyland or Universal Studios).
There's also lots of pay arcade and claw machines.
If you have patience and time, this could be a good outing for you (for me, this was towards the end of my Tokyo stay, and I had had enough of all this queueing)
