My wife and I visited an art gallery located in Ohme, Metropolitan Tokyo, which displays on permanent basis the works of a master landscape painter, Gyokudo Kawai. In 1945, Kawai evacuated to this place when his house in downtown Tokyo was burnt down by an air raid in the final stage of World War II. The gallery stands in a tranquil environment on the upstream Tama River with mountains close behind. It has a beautiful stone garden as you can see in these photos.
Gyokudo's portrait and some works of his are shown here.
