Harvey Saburo Hayashi(林 三郎) (February 22, 1867 – June 1, 1943) was a Japanese doctor who practiced in Kona, Hawaii.
He graduated from Aomori Prefectural Medical School in 1884, then moved to America, where he was a migrant worker until he saved up enough money for medical school, since he came to America against his father's wishes and therefore didn't have financial support.
In 1893, he moved to Honomu in the Big Island of Hawaii's Kona district at the invitation of Jiro Okabe.
[2] Hayashi opened a practice in Honomu when he first arrived in Hawaii, but he soon moved it to Kailua-Kona.
[7] Hayashi's wife, Matsu, taught at the school until a full-time teacher (Sukezo Takeda) was hired.
