Mega Web is a giant exhibition/theme park located in Tokyo featuring: a Toyota City Showcase, the Toyota Design Exhibition and the most seemingly interesting, the Toyota History Garage.
The history garage, contains restored cars of various American, European & Japanese models and makes. It would be one of the places to consider by anybody visiting Japan.
I was looking for valuable images of the place then I found a post, on Garage 36 Blog (a BMW E36 Blog), about a Japan trip in which the history garage was visited. You can also check their posts about the Full Story starting from the first day.
Here is some photos, in the eyes of the blogger that visited the place:
Heavenly garage where they work on the actual classics:
