A church in Chiyoda, Japan, designed by local design studio Tezuka Architects. A pipe organ is installed in the chapel. The thick walls of the chapel are designed to withstand the deep bass of the organ, and the walls also have a sloping structure to prevent flutter echoes. Using walls as an acoustic device, each wall has a different tilt to allow the sound to recover naturally, and the sound through the surface of the wall will be further softened.

There are no windows on the sides in which the only light source depends solely on the light penetrating from skylights above. The depth of the skylight is slightly different for each window in consideration of its size and the direction of light. At the time of worship, an angel ladder would appear. However, this phenomenon does not appear all year round, and that only diffused light appears when the sun is shallow. During sunset, the skylight will be tinted with a dyed ultramarine tone. This is due to the dispersal of direct light when light collides with the atmosphere creating a bluish tint.
