Kokichi Yamaguchi (山口孝吉, Yamaguchi Kōkichi, 16 November 1873 – 1937) was a Japanese architect active at The University of Tokyo.

## Biography

Yamaguchi was born in Kagoshima prefecture in 1873 and graduated from The University of Tokyo in 1897. He first worked as an architect for the Ministry of Education. From 1907 to his retirement in 1923, he worked for the Building and Repairs section at The University of Tokyo. In 1912 he was promoted to the head of the section.

## Architecture

Yamaguchi worked on several buildings at Hongo Campus during his time at the University of Tokyo Buildings and Repairs section, but most were destroyed only a few months after his retirement in the 1923 Great Kanto earthquake. Yamaguchi’s successor as head of the Building and Repairs section, Yoshikazu Uchida, oversaw the rebuilding of the campus and designed most of the present buildings. Uchida’s work dominates the present campus and Yamaguchi is therefore not well remembered. This is perhaps evident from the fact that the auditorium Yamaguchi designed is presented with “designer unknown” in the book commemorating the 100-year history of Hongo campus, published in 1988. The only remaining building of Yamaguchi on Hongo Campus is the East Chemistry Building, which is a two-story red brick building located east of Yasuda Auditorium. This building was the first construction on campus to use reinforced concrete. Yamaguchi also constructed a similar north section for the chemistry department, which was completed in 1923, a few months before the earthquake. This building did also survive the earthquake but was demolished in 1984.

A few examples of Yamaguchi’s work can be seen in the model collection of the University Museum of The University of Tokyo. Four of Yamagchi’s buildings from the University were created in scale 1:100 by the Italian model maker Giovanni Sacchi in 1997.
