Makoto Iwamatsu, also known as Mako, was born in Japan and spent his early years living with his grandparents while his parents pursued art studies in the United States.
As World War II broke out in 1941, Mako's parents remained in the U.S., working for the Office of War Information, and were eventually granted U.S. residency by Congress.
Mako joined his parents in New York and initially studied architecture, but his true passion lay in the theatre.
He entered the U.S. Army in the early 1950s and discovered his talent for acting, performing in shows for military personnel.
This experience inspired him to abandon his architectural pursuits and enroll at the renowned Pasadena Community Playhouse.
After completing his studies, Mako appeared in numerous stage productions and television shows, earning an Academy Award nomination for Best Supporting Actor in 1966 for his role in The Sand Pebbles.
He continued to work steadily in feature films, showcasing his remarkable talent and versatility.
Mako also had a successful career on Broadway, starring in the leading role of Stephen Sondheim's Pacific Overtures and co-founding the esteemed East-West Players theatre company in Los Angeles, where he served as artistic director.
Tragically, Mako passed away on July 21, 2006, at the age of 72, following a long battle with cancer.
He left behind his wife, Shizuko Hoshi, who also co-starred in episodes of M*A*S*H, as well as his children and grandchildren, who cherished his memory.
