Worth the entire trip to Japan. Do not miss it and leave at least 4hrs to explore. Also, it's fairly hard to find the entrance so if you go through the car thing and upstairs you can walk over a walkway to get there. I found it by randomly walking down an alley and found a back way. The entrance is right by the Ferris wheel. Oh and you will likely wait in a long line to get in even if you already have a ticket. Again, worth it!
