Western-style painter Ei Nakau's preferred style is abstraction. In 1968, he began a series titled "Cielito Lindo," a project to which he still contributes 40 years later. As is evident in the way he pours paints directly onto the canvas, Nakau values unpredictability and favors experimentation with improvisation. However, he is best known for his emphasis on the color blue, with his works particularly evocative of the sky and space.

Motosaburo Nishimura (1917-2002), another abstract painter, was also attracted to the color blue, often focusing on the ocean and harbors as subjects.

This exhibition showcases 40 blue-themed paintings, and includes the work of other artists such as Hide Kawanishi and Kazuko Kawamoto; till March 31.
