He also went to Hamburg, Germany where he studied with Austrian mathematician Emil Artin.
In 1932, he attended the International Congress of Mathematicians in Zurich.
As an undergraduate, he published two papers in the Japanese Journal of Mathematics and the Proceedings of the Imperial Academy of Tokyo. Both of his papers appeared in print in 1928. After completing his undergraduate degree in 1929, he stayed at Tokyo and worked under Takagi for his doctorate.
