Takatō Castle Site Park, Castle ruins park in Ina, Japan.

The park spreads across hillside terrain with approximately 1500 cherry trees, while old stone foundations and earthen barriers from the original fortification remain visible as you walk through the grounds. The pathways are designed to guide visitors past these remnants, creating a connected journey through history.

Takeda Shingen's retainer Yamamoto Kansuke planned the castle's layout, and members of the Takeda family served as lords. It fell in 1582, when the castellan Nishina Morinobu, Shingen's fifth son, was defeated; Shingen's daughter Matsuhime, Morinobu's sister, was in the castle, and the attacking commander Oda Nobutada, Nobunaga's eldest son, was her former betrothed. In 1714 the Edo-period Oshima-Ikushima affair brought Ikushima to Takato under the care of the domain lord Naito Kiyokata.

The Takato-Kohigan cherry trees were designated a Nagano Prefecture Natural Monument in 1960. Since 1978 the park has charged admission only during the blossom season, when the Takato Castle Site Park Cherry Blossom Festival runs from early April to early May with evening illumination.

The blossom season runs from early April to early May, when the Takato-Kohigan cherries flower and the park charges admission. A free large car park operates shuttle buses to the grounds for 100 yen one way; when queues are long, some visitors walk from the car park instead. From Ina City Station, a JR bus reaches Takato Station in about 25 minutes, and the park is a 15-minute walk from there.

The cherries were planted in 1876 by former retainers of the Takatō domain, after the castle grounds had been stripped and left waste following the 1871 abolition of the domains. The grove was designated a Nagano Prefecture natural monument in 1960. The trees are the Takatō-kohigan variety, and the park has charged admission during the blossom season since 1978.
