is a Japanese dry landscape garden and nationally designated Place of Scenic Beauty in the city of Hirakawa, Aomori Prefecture, Japan.
The garden was laid out in the Genroku era of the Edo period (1668-1703) at the residence of the Seità  family, to commemorate the visit of a court noble, Fujiwara Tadanaga, to this location to plant a keyaki tree. The Seità  family claimed descent from Seità  Morihide, a retainer of Hà Âjà  Tokiyori in the Kamakura period. According to legend, Hà Âjà  Tokiyori had an affair with a lady-in-waiting named Karaito Gozen. This incurred the wrath of his wife, and fearing for Karaito Gozen's safety, he entrusted her to Seità  Morihide with orders to hide her in a distant location with promises that they would eventually be reunited. Seità  Morihide took her to distant Tsuruga by sea, to a village in what is now Fujisaki, Aomori. However, after years went by, Karaito Gozen feared that Hà Âjà  Tokiyori had a change of heart and she committed suicide by throwing herself in a pond. Unable to face Tokiyori, Seità  Morihide decided to remain in Tsugaru. His descendants became great landholders, and Fujiwara Tadanaga was visiting sites connected with this legend.
The garden covers an area of . The original keyaki tree no longer exists, and the garden was extensively renovated in the late Edo period; however, it can be considered a prototype of the Oishi Bugaku Ryu style of Japanese gardens, as later seen at the nearby Seibi-en.
The garden is approximately a 10 minute walk from Tsugaru-Onoe Station on the KÃ Ânan Railway.
