Abstract
The architecture of HORIGUCHI Sutemi is one of the most important documents for understanding the modernization of architecture in Japan. For a long time, his documents have been protected in several places by HORIGUCHI Stemi Architectural Archives and its volunteers. Now NAMA has received a donation of a complete set of the materials from them and Horiguchi's relatives. The purpose of this paper is to present the history of this donation and to discuss its value and importance.
