Aside from reading, I tried making satsuma imo (Japanese sweet potato) stew. That turned out quite well.
I also ordered some software: one set of Japanese fonts (the drool got the better of me) and one Japanese calligraphy program. I've been wanting a calligraphy program since I saw one (possibly this same one) last winter with the rest of the New Year postcard supplies. I bought a book several months back about Japanese sumi-e painting, but I haven't quite broken down and bought all the brushes, ink, and paper. I figure this is a good compromise.
