Morinosuke Chiwaki (血脇 守之助, Chiwaki Morinosuke; 2 March 1870 – 24 February 1947) was a Japanese dentist, dental educator and administrator who played an important role in the development of modern dental education and professional dentistry in Japan. He succeeded to the management of Takayama Dental School and developed it into the institution that later became Tokyo Dental College. He also served as the first president of the Japan Dental Association and was a patron of bacteriologist Hideyo Noguchi.

Early life and education

Chiwaki was born on 2 March 1870 in Chiba Prefecture. He graduated from Keio Gijuku in 1889. After working as a journalist and an English teacher, he entered Takayama Dental School in 1893 and passed the national examination for dental practice in 1895.

After qualifying as a dentist, Chiwaki spent a period in China before returning to Japan. In 1899, Kisai Takayama transferred management of the school to him. In 1900 Chiwaki renamed the institution Tokyo Dental School and became its head.

Development of Tokyo Dental College

Under Chiwaki's leadership, the school was reorganized and expanded. In 1907 it was officially recognized as Tokyo Dental Medical College, with Chiwaki serving as its director. The institution later developed into Tokyo Dental College.

Chiwaki promoted the modernization of dental education and worked to strengthen the school's academic and clinical foundations. Among those associated with the institution during his leadership were Tsurukichi Okumura and Kanae Hanazawa, both of whom later played important roles in Japanese dental education and research.

The founding philosophy traditionally associated with Chiwaki at Tokyo Dental College is "Character Building is the First Step in Becoming a Dentist" (歯科医師たる前に人間たれ). The college continues to present this principle as part of its educational identity.

Support for Hideyo Noguchi

Chiwaki is also known for his support of Hideyo Noguchi. In 1896, after Noguchi moved to Tokyo to pursue a medical career, he came into contact with Takayama Dental School and Chiwaki. Contemporary and later accounts describe Chiwaki as one of Noguchi's important patrons and supporters.

A historical study of Noguchi's biographies records that Noguchi visited Takayama Dental School shortly after arriving in Tokyo, met Chiwaki there, and began a lifelong friendship with him. Noguchi subsequently taught pathology and pharmacology at the school for a period.

Leadership in Japanese dentistry

In 1903 Chiwaki helped establish the Dai Nippon Shikai-kai, a predecessor of the Japan Dental Association. He later served as the first president of the Japan Dental Association and was involved in the development of organized dentistry and dental regulation in Japan.

He was also active in efforts to standardize dental education and professional practice. A later historical account described his career as closely linked to the development of the dental curriculum in Japan during the formative period of modern Japanese dentistry.

Chiwaki retired from the leadership of Tokyo Dental Medical College in 1943, when Tsurukichi Okumura succeeded him. Chiwaki died on 24 February 1947.

Legacy

Tokyo Dental College continued to commemorate Chiwaki after his death. As part of commemorative activities marking the college's 80th anniversary and the centenary of Chiwaki's birth, a biographical project was undertaken, resulting in the publication of Chiwaki Morinosuke-den (血脇守之助伝) in 1979.

The presentation ceremony for the completed biography was attended by senior representatives of Tokyo Dental College, including then-president Seiichi Matsumiya.

A monument commemorating Chiwaki stands in Abiko, Chiba Prefecture.
