Yoshio Mochinaga

After entering government service, Mochinaga served as a district administrator in Wakayama Prefecture and then as an official in Hiroshima Prefecture before returning to the central bureaucracy.^[3] By the 1930s he had advanced through the Social Bureau of the Home Ministry, serving as chief of its welfare, protection, and general-affairs sections.^[3]

In 1938 he became a secretary in the Ministry of Health and Welfare and director of operations at the War Wounded Protection Institute.^[3] On 15 July 1939 he was appointed Governor of Ehime Prefecture.^[3] During his year in office he promoted wartime mobilisation campaigns, drought-relief measures, the expansion of Matsuyama through merger with neighbouring municipalities, and the national transfer of Yuge Merchant Marine School.^[3]

On 24 July 1940 Mochinaga left Ehime to return to the central government as Director of the Labor Bureau of the Health and Welfare Ministry, later also heading the Diligence Bureau.^[3] In July 1943 he was appointed Governor of Mie Prefecture.^[4] The official Mie wartime chronology records his appointment in July 1943 and the accession of his successor in April 1945.^[4] During his tenure, the prefecture continued wartime mobilisation, including student labour mobilisation, and experienced the 1944 Tōnankai earthquake.^[4]

On 21 April 1945 Mochinaga was transferred to become Governor of Hyōgo Prefecture.^[5] The official Hyogo governor list gives his tenure as lasting until 27 October 1945.^[5] On that date he became the 28th Director-General of the Hokkaidō Agency.^[1] The Hokkaido Government archive gives his term as running from 27 October 1945 to 25 January 1946.^[1]

A study of the first postwar gubernatorial elections notes that a large group of wartime governors fell under the occupation purge because of their links to the local structure of the Imperial Rule Assistance Association, and that former governors of prefectures including Hyōgo and Mie were among those affected.^[6] After leaving office, Mochinaga worked as a lawyer.^[7]

After the purge was lifted, Mochinaga entered electoral politics. He was elected to the House of Representatives from Miyazaki 2nd district at the 1952 Japanese general election as a Liberal Party candidate, and was re-elected at the 1953 Japanese general election.^[8][9] He was defeated at the 1955 Japanese general election.^[9]

Later in life, Mochinaga again worked in public-service and legal roles in Miyazaki. The Miyazaki Prefectural Labour Relations Commission annual report lists him as a lawyer who served as a public-interest member of the commission during its 21st and 22nd terms.^[7] He died on 31 August 1979.^[3]
