He held a Doctor of Science degree and served as the director of the Metal Materials Technology Research Institute of the Science and Technology Agency. He also was the principal of Taga Technical School and served as the president of the Japan Society of Mechanical Engineers.

He was born in Shibuya-ku, Tokyo. His father was Utarō Hashimoto, who was an executive at Dai Nippon Beer (now Sapporo Beer). Uchi Hashimoto's mother was Matsu, who was from Kumamoto Prefecture. His maternal grandfather was the sister of the military officer Masao Ishimitsu, and he was the niece of Lieutenant General Masao Ishimitsu.

In terms of education, he graduated from the Mechanical Engineering Department of Tokyo Higher Technical School (now Chiba University Faculty of Engineering) in 1919, and then studied physics at Tohoku Imperial University (now Tohoku University). In 1923, he became an assistant professor at Tokyo Higher Technical School, and in 1926, he studied abroad in Germany and the United States for metal materials research. In 1929, he became a professor at Tokyo Higher Technical School.

From pre-war through post-war, he served as a lecturer at Tokyo Imperial University (now the University of Tokyo), and in 1944, as a chief researcher on steel die casting as a wartime researcher.
