This study clarifies the concepts underlying the layout plans for Yokufuen Main Site and Yokohama Branch Site, both asylums built in 1928, and the overseas influences on these plans. For this purpose, a literature survey was conducted, including foreign documents referenced by the designer, Tatsundo Toki. The results showed that the sites’ southern side was opened for outdoor activities. Additionally, the cottage system was implemented to create a home-like atmosphere. In particular, the outdoor cultivation seems to have been inspired by the work of A. Johnson, and the V-shaped building layout by the Fazakerley Sanatorium Competition in Liverpool.
