Shizuoka Prefecture is a prefecture of Japan located in the Chūbu region on Honshū island. The capital is the city of Shizuoka. The prefecture was previously divided into Tōtōmi Province, Suruga Province and Izu Province. The most noted history of the prefecture is that it was once home to the first Tokugawa Shōgun. The region was held by Tokugawa Ieyasu until he conquered the lands of the Hōjō clan in the Kantō region and gave his lands to the stewardship of Oda Nobunaga. After becoming shōgun Tokugawa took the land back for his family, particularly putting the area around modern-day Shizuoka city under direct shogunal supervision. It once again became the residence of the Tokugawa family after 1868, with the creation of Shizuoka han. Shizuoka Prefecture is an elongated region following the coast of the Pacific Ocean at the Suruga Bay. In the west, the prefecture extends deep into the Japan Alps, while farther east it becomes a narrower coast bounded on the north by Mount Fuji, until it comes to the Izu Peninsula, a popular resort area pointing south into the Pacific. Every 100–150 years, an earthquake of disastrous proportions called the Tokai Earthquake occurs in the Shizuoka Prefecture. The previous earthquake was in 1854.
