This paper aims to delineate the way Omote-genkan (main entrance) changed over time in residential works designed by Isoya Yoshida. Eighty-four works were analyzed on the basis of the name used on drawings, flooring material, door type and difference in level between the dirt floor and flooring. This revealed that, from 1930 to 1940, the material used to finish floors changed from tatami to wooden flooring, the fittings disappeared, and the height of the step became shorter. As a result, Omote-genkan changed from an individual space to a unified space.
