Overview (history, characteristics, attractions)
Matsushiro Castle is a castle ruin in the Matsushiro district of Nagano City. It dates back to the Sengoku period and was the center of the Matsushiro domain, ruled by the Sanada clan, during the Edo period. It was also known as Kaizu Castle in the past. While the castle tower no longer remains, remains of earthworks, dry moats, and other structures, as well as the castle townscape from the domain era, remain in good condition, making it a popular base for historical walks and touring historical sites related to the Sanada clan. Another attractive feature is the concentration of attractions around the castle ruins, including a Sanada museum, samurai residences, and the Matsushiro Imperial Headquarters (underground bunker).
