While in Tokyo I stopped by to check out Caricature Japan's Asakusa shop. It is in a great location, and is the coolest booth by far. I got a sketch, you can see below, by Yuta Honma, who you can see above. You can see more of his great stuff at http://hon-maburo.blogspot.com/
Caricature Japan was having an exhibition of themed artwork and doing live sketches for a nearby for a comedy film festival. Kage, Sousuke, and Shiori were all there. Here you can see Kage doing a nice sketch with some of the art in the background.
I was lucky enough to end up with my second sketch by Kage. A good art day! You can see more of his work at http://blog.livedoor.jp/donkage/. Good stuff.
