The news release on January 8 advertises the opening of a "Nishio Ishin Anime Project" exhibition in the 'blood donation room' (マジかよ？), 'akiba:F', in Akihabara. The exhibition, featuring books, original drawings, CELs (I assume), music and goods etc from Bakemonogatari and Katanagatari, opened on the 9th, and will run through to the 31st of March.
Maybe I should have gotten my passport done in Tokyo instead! gah
