Former Senator Daniel K. Akaka, a Democrat who represented Hawaii for 36 years in Congress and successfully fought for the belated recognition of Asians and Asian-Americans who had fought for the United States in World War II, died on Friday in Honolulu. He was 93.

Jon Yoshimura, the senator’s former communications director, confirmed the death, saying Mr. Akaka had been hospitalized for several months, The Associated Press reported.

A World War II veteran, Mr. Akaka sponsored legislation in 1996 that led to a re-evaluation of the service records of Asian-Americans who had fought in the 442nd Regimental Combat Team and the 100th Infantry Battalion during the war.
