I became interested in Japanese castles when I was an AFS high school exchange student to Tokyo in 1992. I went with my host family to visit my host father's birthplace of Matsumoto (Nagano Prefecture) where I saw Matsumoto castle. During that summer I also visited castles in Nagoya, Inuyama and Gifu. I visited more castles as a college exchange student to Nagoya in 1995-1996 and saw even more of them while I was working in Fukushima (1997-1999). Now that I am back in Japan (2001- ?) I'm regularly adding new content.

My aim is to make this the most authoritative and comprehensive site available in English on Japanese castles. If you have any comments or suggestions please email me.
