Handwritings hung in the Hajime Hoshi Memorial Exhibit Hall

The Hajime Hoshi Memorial Exhibit Hall is located at Hoshi University (Tokyo, Japan). There, over 100 articles left behind by Hajime Hoshi, the founder of Hoshi Pharmaceutical Company and Hoshi University, are on display. In this paper, references are made to handwritings written in Japanese sumi ink and hung in the Exhibit Hall. On the wall of the hall are hung four writings by Hajime Hoshi, one big writing by Shinpei Goto, vice premier and the mayor of Tokyo in the early 20th century, and two writings by Koki Hirota, premier executed after the end of World War II. The writings by the latter two were written for Hajime Hoshi. From the viewpoint of historical, literary and friendship aspects, analytical investigations of these handwritings were conducted.
