In 1909, Tomita Keisen travelled to China and painted cormorant fishing by the Yangtze River and Chinese Mountain-water. Later, he painted many masterpieces depicting the four-seasons scenery of Kyoto.
Tomita is a friend of the France Ambassador Paul Claudel of the time, who was a poet. They collaborated to create poems and paintings.
Having attended the exhibitions of Japan Visual Arts Academy (Nihon Bijutsuin), the works of Tomita was highly regarded by other well-established Japanese painters including Yokoyama Taikan (a key figure in founding the painting technique of Nihonga), who said that Tomita Keisen is such a precious talent that only appears once in a hundred years.
