According to the agency, the building completed in 1972 originally served as the home of the Chichibu family. Post-renovation, the two-story reinforced concrete home has a total floor space of 2,972 square meters, including the basement -- roughly 1.9 times larger than before. The residence consists of the family's private rooms, spaces for official duties and staff offices. The media tour covered a large hall and a parlor in the official duty area, plus a large dining room, among other rooms. The marble shelves and a chandelier in the large dining room were part of the original building, and some of the furniture, lighting and carpeting has apparently been reused.
