Ohara Koson (1877–1945) was a prolific Japanese painter and printmaker celebrated as a master of kachō-e (bird-and-flower) designs. He was a central figure in the Shin-hanga ("new prints") movement, which revitalized traditional woodblock techniques by incorporating Western-style realism and perspective.

Koson's work is characterized by its meticulous attention to detail, vibrant colors, and life-like portrayals of nature. 
Movements: He bridged the gap between the traditional Meiji-era ukiyo-e style and the modern 20th-century Shin-hanga movement.
Global Popularity: While his work was largely overlooked in Japan during his lifetime, it achieved massive success in Europe and the United States.

Shōson: Adopted around 1926 when he began collaborating with the influential publisher Watanabe Shōzaburō.
Hōson: Used for a limited number of works published by Kawaguchi and Sakai between 1929 and 1931.
