Koso Sato (1948–2018), born in Akita, Japan, was a significant artist whose career spanned Japan, France, and Taiwan. A graduate of Musashino Art University and the ?cole Nationale Supérieure des Beaux-Arts in Paris, he studied under Saburo Miyamoto and Minoru Fukuda. After a 1979 award in Japan, he moved to Taiwan in 1989, where he lived for nearly 30 years, often called "the Japanese painter who is half-Taiwanese," profoundly influencing local art.

His work, often showcased at venues like the Asia Art Center and National Chiao Tung University, combined Fauvist colors and Expressionist lines to create "modern myths." His style evolved from romanticism to a unique blend of Neo-Cubism and abstraction, offering a vibrant, deconstructed view of nature.
