The acronym T.Y.O.W. corresponds to a Japanese lens maker based in Tokyo, whose full name is currently unknown. It made Taiyo-Anastigmat barrel lenses for large format cameras. These are usually marked T.Y.O.W. TOKYO TAIYO–Anastigmat. The brand name certainly comes from the word taiyō (太陽), which means "sun" in Japanese.
The Taiyo lenses were already existing in 1941.[1] They were made by a relative of Mr. Yamasaki, founder of Yamasaki Kōgaku Kenkyūsho and maker of the Congo lenses.[2]
