It is one of the few castles in Japan that exist in Tianshou Pavilion. It is located in the inland location of Nagano Prefecture. Although there are high-speed arrivals, it is certainly not as convenient as the coastal Osaka Castle and Himeji Castle. Because of this, there are not many tourists, and I came here on a snowy day, the scenery is great. Although the scale of Matsumoto City is not large, it is the only composite connected Tianshou complex in Japan, centered on Datianshou, surrounded by dry Xiaotianshou, Chenxi Vice-Chun, Moon Seeing, and Watanabe, so it is also known as one of Japan's "national treasures of four cities". You need to take off your shoes to climb the building, and the staff will give you a rubber bag to visit with your shoes. There is no heating in the room, it is still very cold to walk up and down the wooden board, please wear thick socks in winter. The most distinctive feature of the moon in the southeast of Tianshou Pavilion is that it is a prominent, three-faced house, used for feasting and enjoying the moon, and other facilities that Tianshou Pavilion does not have.
