PEARL HARBOR, Hawaii (AP) — The families of five Hawaii men who served in a unit of Japanese-language linguists during World War II received posthumous Purple Heart medals on behalf of their loved ones on Friday, nearly eight decades after the soldiers died in a plane crash in the final days of the conflict.

“I don’t have words. I’m just overwhelmed,” Wilfred Ikemoto said as he choked up while speaking of the belated honor given to his older brother Haruyuki.

The older Ikemoto was among 31 men killed when their C-46 transport plane hit a cliff while attempting to land in Okinawa, Japan, on Aug. 13, 1945.

“I’m just happy that he got recognized,” Ikemoto said.

Army records indicate only two of the 31 ever received Purple Heart medals, which the military awards to those wounded or killed during action against an enemy.

Researchers in Hawaii and Minnesota recently discovered the omission, leading the Army to agree to issue medals to families of the 29 men who were never recognized. Researchers located families of the five from Hawaii, and now the Army is asking family members of the other 24 men to contact them so their loved ones can finally receive recognition.
