There is a huge trompe l'oeil (optical illusion or what the Japanese call trick art) display at the Osaka Station.
To get a nice view of it you need to go up to the 7th floor and look out over the "Toki no Hiroba".
They also have marked spots to take photos too.
Here's Satoshi "balancing" on a log...
Fun, yeah?! Not sure how long this display will be there, so if you get a chance, go soon!
