The 21st Century Museum of Kanazawa opened in 2004 and is designed in a disc-like design as if it were a UFO landing in the center of Kanazawa. All walls are made of glass and the building has five gates open in different directions to the city. The gallery displays experimental modern art that visitors can touch or sit on, and is ideal for children and adults. Highlights include the "pool" of Leandro Erlich , which makes visitors feel as if they are standing at the bottom of the pool, and walls decorated with flowers collected from the suburbs of Kanazawa.
