The YUMON is a pair of two curved lines, one bulging and the other indented, that boldly and rhythmically compose the space. It is inspired by the traditional Japanese pattern “Tatewaku,” which has been used since “the Heian” period (794-1192) to simply express the appearance of rising water vapor. Since ancient times, the pattern of “Tatewaku” has also been referred to as the shimmering flames of a rising sun or rising clouds and is considered an auspicious and auspicious pattern.
