This site does "urban exploring" of closed or abandoned places.
They took photos of Tokyo Sesame Place 6 years after it closed.
I have archived them here, in case they are ever removed from their site.

This was an indoor play area for toddlers:

Rainbow Pyramid was a play area at Tokyo Sesame Place. It was the same as the Rainbow Pyramids in Texas and Pennsylvania.
Guests would toss a ball at a pyramid that had jets of air coming out of it.
Air rushing over top of the spinning ball would move faster than the air below keeping the ball suspended.
The signage in Tokyo had Sesame Street character Dr. Nobel Price:
At the top of the Tokyo Sesame Place escalator you would be at the Big Bird head. You could continue through Big Bird's mouth up to Barkley's Walkway (a narrow observation deck) or you could stay at Sesame Square which would give you access to the rest of the attractions.
Sesame Square had the round sign similar to the signs Milton Glaser designed for Sesame Place in Langhorne, PA.
Below is an image created from stills from a video sweep of the area.
Many pictures make it look like the Big Bird head was directly in front of the escalator, but it was a dozen or so feet back, as you can see in this picture:
