Tsukama
Tsukama lies in the Matsumoto basin of central Shinano, beneath the mountains to its west. The castle at Matsumoto grew from an earlier stronghold called Fukashi. After the fall of the Takeda in 1582, Ogasawara Sadayoshi took possession and set about improving the castle and its town. Ishikawa Kazumasa entered in 1590; his family built the great keep, probably in 1593–94, giving Matsumoto one of the most imposing castles in Shinano.
