World War II Medal of Honor Recipient. He served in the United States Army during World War II as a Staff Sergeant in Company B, 100th Battalion (Separate), 442nd Infantry. He was awarded the CMOH for his bravery at Cerasuolo, Italy, on November 29, 1943. His citation reads "Sergeant Ohata, his squad leader, and three men were ordered to protect his platoons left flank against an attacking enemy force of 40 men, armed with machine guns, machine pistols, and rifles. He posted one of his men, an automatic rifleman, on the extreme left, 15 yards from his own position. Taking his position, Sergeant Ohata delivered effective fire against the advancing enemy. The man to his left called for assistance when his automatic rifle was shot and damaged. With utter disregard for his personal safety, Sergeant Ohata left his position and advanced 15 yards through heavy machine gun fire. Reaching his comrades position, he immediately fired upon the enemy, killing 10 enemy soldiers and successfully covering his comrades withdrawal to replace his damaged weapon. Sergeant Ohata and the automatic rifleman held their position and killed 37 enemy soldiers. Both men then charged the three remaining soldiers and captured them. Later, Sergeant Ohata and the automatic rifleman stopped another attacking force of 14, killing four and wounding three while the others fled. The following day he and the automatic rifleman held their flank with grim determination and staved off all attacks. Staff Sergeant Ohatas extraordinary heroism and devotion to duty are in keeping with the highest traditions of military service and reflect great credit on him, his unit, and the United States Army.". He was originally awarded the Distinguished Service Cross for his bravery that day, a review years later determined he and 21 other Japanese-American soldiers were denied Medal of Honor consideration due to their ethnicity. He was posthumously awarded his Medal on January 21, 2001.
