Obon Toro Nagashi is the floating-lantern ceremony held at night, when hundreds of warm amber washi paper lanterns are set adrift on a black river. Each candle-lit glow is doubled by its reflection on the rippling water, a spectacular play of light and dark against near-black night water tinged with cool blue.

This design system distills that solemn rite into digital form: amber lantern glow on a near-black ground, mirrored reflections, soft candle bloom, and Japanese Mincho serif type — the dead guided home by lights on the water, warm and impermanent.
