The Imperial Household Agency learned records of Empress Kojun (1903-2000) will be completed in March 2025. The project began in April 2008 as a 12 year plan, collecting diaries of close aides, official documents from IHA and local governments related to visits domestic & foreign, documents from former Kuni-no-miya family, newspapers and magazines, etc.
Empress Kojun's chronicles or Veritable Records (Jitsuroku 実録) took longer due to delays in the compilation of the Emperor Showa Chronicles which began in 1990 (completed in 2014 with 2 extensions) and work to publish his chronicles for the public. The agency has earmarked about 5.62 million yen for editing costs in FY2024 general account budget request. Empress Kojun's Chronicles will be structured like Emperor Showa’s, a chronological list of events and is expected to be half the size of Emperor Showa's 61 volumes (~12,000 pages)
After the IHA delivers the book to the Emperor, it will make it an administrative document subject to information disclosure and will be able to view and copy it. Publication for the general public has not yet been decided, but the agency is considering making it available on its website.
