Yogaisan Castle, Mountain fortress in Kofu, Japan
The castle compound measures 73 meters east to west and 22 meters north to south, with multiple defensive layers of trenches and earthen walls.
Built in 1520 by Takeda Nobutora, the castle served as a strategic fallback position during the intense conflicts of Japan's Sengoku period.
The site contains the Suwa Mizu well and stone statues of Takeda Fudo Son, marking the birthplace of the military commander Takeda Shingen.
Visitors can reach the castle ruins from Kofu Station by taking a bus to Sekisuiji stop, followed by a 15-minute walk to the trailhead.
The fortress includes distinctive defensive features such as masugata gateways and multiple archaeological remains that display military engineering from medieval Japan.
