In Japan, marumado were first designed for tea houses and temples. Their circular design elegantly framed a scenerey while hiding unnecessary views to the selected scenery.
All varieties of marumado create a soothing and scenic atmosphere. However, these particular windows with the missing bottom curve are designed with a further consideration: that the missing part continues beneath the ground, under the earth, from where all life begins and returns.
The Maru kanji 円 stands for: circle, unending, harmony, ellipsies, as well as the symbol for the Japanese currency Yen.
