Japanese Art and Culture
Map of Japan - Engelbert Kaempfer - c 1727
From 1989 to 2008 my interest towards Japan was limited to Aikido. Towards the end of 2007 I took an interest in Shodo and the two things have cross-pollinated in a growing interest for Japanese art and culture.
I am far from an expert in any of these, so I think that the "hobby" category is still the best place for this.
