Grounded on tatami mats, a low platform bed with slatted wood headboard and soft cove lighting anchors this Zen bedroom beside a rain-washed courtyard. A round washi lantern casts geometric light on textured plaster, while bamboo blinds temper the floor-to-ceiling glass. Linen bedding in earthy taupe, honey wood, and charcoal concrete forms a restrained palette, balancing natural materials, shadow, and calm proportion in Japanese simplicity.
