Jcastle.info aims to be the most comprehensive guide to Japanese castles available in English. You can start by viewing profiles of the castles below. Login to record your castle visits or write pages of your own.
I'm still rebuilding the Jcastle.info site due to some problems with my old server. Most of the functional work is done, it's mainly cleaning things up and making a newer and better design that's remaining, but I've started publishing new content. Please enjoy and let me know if you run into any difficulties or have feedback and suggestions for improvement.
