Geography

Arai was located at the southwest end of Shizuoka Prefecture, with part of Lake Hamana located within the town boundaries. The town was on the Enshu Sea of the Pacific Ocean, with a temperate maritime climate with hot, humid summers and mild, cool winters.^{[citation needed]}

History

Arai was located in former Tōtōmi Province, and was largely tenryō territory under direct control of the Tokugawa shogunate in the Edo period, when it was called Arai-juku, and prospered as a post town on the Tōkaidō highway connecting Edo with Kyoto. During the cadastral reform of the early Meiji period in 1889, the area was reorganized into Arai Town within Fuchi District, Shizuoka Prefecture. Fuchi District was merged into Hamana District in 1896.^{[citation needed]}
