Abstract
Tokuriya in Kiso Narai was used as an inn since Edo period. We were deeply moved by the hearth space where natural light is visible. We took 11 students of architecture to the site and asked them to record the impressive images of the space and their physical causes, in sketches and phrases. We obtained 12 spatial images and identified physical causes. We classified the images into 5 types : rising space, seperated upper and lower spaces, unified space, connected upper and lower spaces, and enclosing sunbeam space. As the causes, we identified a luminous skylight, pale light, and a changing luminous sunbeam. We also identified other objects and their relation in arousing such images.
