Minoru Kusuda (1924-2003) served as chief secretary to Prime Minister Eisaku Sato and continued to support his administration.
This second phase of the project begins with the Kishi and Ikeda administrations, which preceded the appointment of Kusuda as chief secretary, and continues with various documents from the Sato administration, which are addenda to the first phase of the project.
The second phase consists of a vast amount of previously unpublished materials from the Fukuda administration, the Shintaro Abe administration, and the Takeshita administration after the resignation of Sato.
The collection extends back to the 2000s.
It complements, of course, the Kusuda Collection: Sato Eisaku Papers, published in 2016 and fill in the gaps in the archives of Japanese politics from the late 1970s to the early 1990s.
