Ueno Onshi Park, also known as Ueno Park, is the one of the first public parks in Japan along with those in Shiba, Asakusa, Fukugawa, and Asukayama Parks by the Grand Council of State in 1873.

The grounds occupy the site of the famous Kan'ei-ji Shrine from the Edo Period. With the Meiji Restoration, the land became a government property, and was passed down to Tokyo as a gift from the Imperial State Department in 1924--hence the name of "Onshi" or "Imperial Gift."

The park currently has many cultural attractions such as the main shrine of Kan'ei-ji "Shaden" shrine pavilion and its mausoleum, Toshugu Shrine, a museum, a zoo, and an art museum. With cherry trees exploding their blossoms in spring, the park has a reputation as one of the major cherry blossom viewing spots in Tokyo.
