Located in Uenogaoka Park in Oita City, Oita City Art Museum is a museum where nature and art are in harmony. It is characterized by a quiet environment surrounded by lush greenery, and the museum itself is also a place of relaxation for the citizens.

The museum focuses on collecting works by artists with ties to Oita Prefecture, and stores and exhibits a wide range of genres, including Japanese painting, Western painting, sculpture, and crafts. The permanent exhibition introduces works based on eras and themes, focusing on art pieces with a connection to the local area, allowing visitors to deeply experience the history and development of Oita's art culture.

Special exhibitions are also a major attraction of the museum. There are new discoveries every time you visit, such as diverse art works from within and outside the prefecture and exhibitions focusing on specific themes. In particular, in the field of contemporary art, there are active special exhibitions introducing artists based in Oita and showing trends in contemporary art both in Japan and abroad. These special exhibitions also provide opportunities to experience diverse expressions of contemporary art.

The restaurant "Ironowa" located inside the building is a space that fuses food and art with the concept of "Art x Table". Using an abundance of fresh, safe and secure ingredients sourced from producers in Oita Prefecture, including vegetables grown in the restaurant's own farm, the restaurant offers a healthy menu that makes the most of the natural flavors of the ingredients.
