This past weekend in Tokyo was Comitia 90, an insane 1-day event of epic proportions. Billed by many as the premiere con for indie manga talent, lots of cartoonists, manga nerds, and cool people were in attendance... including Shintaro Kago!
About.com's manga guide and Same Hat buddy Deb Aoki was at Comitia with a group of American cartoonists/manga fans and was lucky enough to meet Shintaro Kago! From her tweets it sounds like she was able to meet the man AND buy an original pen drawing from him.
Here is a photo of Kago (seems to be rocking the winter skullcap & swine flu mask):

Wish I could have been there! Maybe the Spring DESIGN FESTA in Tokyo in May??
