When is the best time to visit Matsuyama, Japan?

Matsuyama is located in Shikoku, with a warm climate and little rain all year round, making it a very suitable place for tourism. In order to attract tourists, the local tourism bureau carefully designs various festival programs throughout the year, such as Matsuyama Castle Spring Festival, Matsuyama Dogo Hot Spring Spring Festival, Hojo Kashima Spring Festival, Dogo Onsen Summer Festival, Matsuyama Autumn Festival, Hojo Autumn Festival, etc. There are festivals, the Yuzuki Castle Moon Viewing Festival, the Hatsuko Festival at Matsuyama Yu Shrine in winter, and the Tsubaki Festival, etc. Therefore, it is suitable for traveling all year round. However, I personally prefer spring, because in Matsuyama, the cherry blossoms are in full bloom from the end of March to the beginning of April. At this time of year, various activities including the "Matsuyama Spring Festival" will be held grandly.
