He graduated in 1919 and furthered his studies at Tokyo Imperial University (now University of Tokyo) in the science department. In 1921, he invented the wired and wireless multiplex telegraph and telephone system which was patented in eight countries. He was an extremely bright young man with a promising future.

In 1922, he entered the university's aeronautical research institute as a researcher. However, his life soon took a downturn from 1923 when he received a military conscription notice. A love interest for marriage also did not work out as desired. His physical health deteriorated and he terminated his own life the following year in 1924 at age 26.
