Ieyasu stands in Hamamatsu

In 1570, Tokugawa Ieyasu moved his base from Okazaki to Hamamatsu, and built Hamamatsu Castle. While residing in Hamamatsu Castle, he faced many hardships, including the Battle of Mikatagahara, offence and defense against the Takeda clan, the murder of his wife Tsukiyama-dono, and the suicide of his eldest son Nobuyasu. Yet, Hamamatsu Castle is also a castle of great importance, where one can discover the brave and resolute side of young and virile Ieyasu. After the downfall of the Takeda clan in 1582, Ieyasu became a great daimyo (feudal lord) active across Japan. He initially reigned over five provinces: Mikawa, Totomi, Suruga, Kai, and Shinano (which respectively correspond to the modern regions or entire prefectures of eastern Aichi, western Shizuoka, central Shizuoka, Yamanashi, and Nagano).
