Based on the motif of Ryusuimon, a characteristic pattern from the Yayoi period, this design features a rhythmic arrangement of patterns with gentle curves like the Seigaiha (blue ocean wave) pattern. Using indigo, a color referred to as “Japan Blue” and influential in western art and culture, the design represents a gentle flow of clear blue water.

Indigo is firmly rooted in the life of townspeople in the Edo period. This traditional color representing Japan reflects their way of life and aesthetics. Ryusuimon is said to be the oldest among all mon patterns inspired by water. This pattern was used to decorate pottery, bell-shaped bronze wares, and wooden products during the Yayoi period. It has implications of grace and valiance.
