Japanese castles I've visited: #59 Matsumoto Castle in Nagano Prefecture. One of the 12 original castle structures and certainly one of the BEST Japanese castles out there. One of my favorite castles in fact. :D
Japanese castles I've visited: #65 Nagoya Castle in Aichi Prefecture. Although it's reconstructed, I'm in love with the main tower. I went during o-bon, so the castle was open at night as well and there was a festival on the castle grounds.
