The origin of Kyushodo kyupodou-Grandpa Sakai's interest: The grandpa's interest in letterpress printing
owner Sakai Kushiro was his letterpress printing after retirement. There are a large number of movable type and correction machines in the printing room. Because it uses letterpress type 9 typeface, it is called "Sakai Kushodo kyupodou".
The subtle concavo-convex character of letterpress printing is greatly different from the current printed matter. Later, the boss also inherited the grandpa's house number, and continued to make new works using the machine left by the grandpa. In the small letterpress printing room of the studio of Kyubodo Kypododou, there are still typewriters and printing machines used by boss Sakai Kushiro's grandfather, Sakai Sakai.
