Shizuoka Prefecture (静岡県 Shizuoka-ken) is a prefecture of Japan located in the Chūbu region of Honshu. The capital is the city of Shizuoka.
Shizuoka Prefecture was formed from the former Tōtōmi, Suruga and Izu provinces.
The area was the home of the first Tokugawa Shogun. Tokugawa Ieyasu held the region until he conquered the lands of the Hōjō clan in the Kantō region and placed land under the stewardship of Oda Nobunaga. After becoming shogun, Tokugawa took the land back for his family and put the area around modern-day Shizuoka city under the direct supervision of the shogunate. With the creation of Shizuoka han in 1868, it once again became the residence of the Tokugawa family.
