Q. How is the main building currently used? It opened in 2001. Until then, wasn't it opened to the public?
Matsui: The Agency for Cultural Affairs entrusted the Tokyo Metropolitan Government with the management of this building which was designated as a national important cultural property. Since then, many people have come to see the building and deepen their understanding of the architectural culture at that time. Visitors have looked at it as a house which was built along with the Japanese-style houses in those days, and as one of the masterpieces by Josiah Conder who was said to be a father of the Japanese modern architecture. We have given priority to the preservation and handing down of the cultural property and continued to work on it. Kyu-Iwasaki-tei had been used as the Ministry of Justice's Judicial Research and Training Institute. I also never thought it has opened as a Tokyo metropolitan park. Therefore, many people still do not know about the garden.
Q. Are the main gate and vegetation largely unchanged?
Matsui: The main gate was placed at the present location after a part of the grounds were sold. Staff members of the Ministry of Justice went in and out from this gate. The original gate was placed at the site facing Kasuga Street. I heard that it was a huge gate made of oak. Horse-drawn carriages were stationed in front of the gate. It was so-called carriage-drive. It corresponds to an approach to a shrine. The vegetation is not largely changed. When we were entrusted with the management of the garden, it was neglected. When we visited the garden in order to carry out opening preparations, native plants grew densely. Weeds in the lawn garden grew as high as a man. I took about a half year to mow the lawn, cut down naturally-grown trees and construct the garden. Many staff members of the Tokyo Metropolitan Government were impressed into the gardening. As a result, the garden reached a level at which it can be shown to the public, but it is still in an incomplete state. (It continues to the bottom step)
