Born in Yokohama, Japan, on 4 November 1886, Togo emigrated to the United States and began an acting career in the early years of the 20th century.

Yamamoto told Blanche Partington in a 1906 interview that he had been "in the dramatic business" in Japan, playing "tragedy, comedy, both" before coming to the United States.

Theatrical manager Kirke La Shelle spotted him in the production and hired him to play the part of a Japanese servant in The Heir to the Hoorah (1905).

[1] Yamamoto subsequently appeared in a number of stage plays, including The Offenders (1908), An American Widow (1909), The Inferior Sex (1910), The Muezzin (1910), Kismet (1911), Miss Phoenix (1913), and others.

In 1925, Yamamoto returned to his native Japan and appeared with Tokihiko Okada in a film entitled Maboroshi no hansen.
