The Diocese of Hakodate was separated from the Northern Vicariate Apostolic of Japan on April 7, 1891, and included Hokkaido (later also Sakhalin) and the seven prefectures of Aomori, Iwate, Miyagi, Fukushima, Niigata, Yamagata, and Akita. It was entrusted to the Paris Foreign Mission Society and Bishop Alexandre Berlioz was appointed the first ordinary.

Later, with the establishment of the Prefecture Apostolic of Niigata on August 13, 1912, the three prefectures of Niigata, Yamagata, and Akita were entrusted to the Society of the Divine Word. On February 12, 1915, when the Prefecture Apostolic of Sapporo, including all of Hokkaido except the district of Hakodate, was established and entrusted to the Fulda Province of the Order of Friars Minor, the area of jurisdiction of the Hakodate Diocese was reduced. On the retirement of Bishop Berlioz, Monsignor Alfred Joseph Wood served for four years as interim ordinary for the Hakodate Diocese. In November 1931 the Hakodate Diocese was entrusted to Canadian Dominicans. Following Monsignor Wood's four years of service, Bishop Andre Dumas, O.P. served as ordinary.

In 1936 Father Marie-Joseph Lemieux, O.P. was appointed to succeed Bishop Dumas. On March 9, he received permission from the Holy See to move the center of the Diocese from Hakodate to Sendai and to change the name of the diocese from the Diocese of Hakodate to the Diocese of Sendai. Later, on June 29, 1936, his episcopal consecration was held. In 1941 Bishop Lemieux resigned and Father Urakawa Wasaburo, a specialist in Japanese Christian history, was chosen to succeed him and was consecrated bishop. In December 1952, the district of Hakodate was separated from the Diocese of Sendai and was incorporated into the Diocese of Sapporo. With this, the area of jurisdiction of the Diocese of Sendai became the four prefectures of Aomori, Iwate, Miyagi, and Fukushima.

In 1954 Bishop Urakawa resigned and Father Kobayashi Arikata was consecrated bishop to succeed him and served as Bishop of Sendai for 22 years. In 1976 Bishop Kobayashi resigned. Father Sato Chihiro, O.P. was appointed to succeed him and was consecrated bishop on March 20. He resigned on June 19, 1998.

After two years' vacancy, Salesian Father Mizobe Osamu was named as the successor of the see on June 12, 2000. He was consecrated Bishop on September 9, 2000.

May 14, 2004, Pope John Paul II appointed Bishop MIZOBE Osamu, S.D.B. as a Bishop of Takamatsu, was installed Bishop on July 19, 2004. Therefore, the place of Bishop of Sendai was vacant about one and a half year.
