With the introduction of the railroad, it became easier and less expensive to escape New York in the summer. Many of the artists came to Cos Cob, due to its attractive harbor. The contrast of the old ships and the new railroad created ideal subjects for art. Many stayed at the Holley Boarding House where they studied with Childe Hassam and John Twachtman, with whom Genjiro studied at the Art Student League in New York City.
Genjiro became friends with Elmer McRae whom he had met at the Student Art League. Genjiro told McRae, “It is the best place to study art” and declared, “I consider it my home. I am treated so nicely.”
