The Namiki Yukari Autumn Leaves rollerball is a work of art that captures the essence of autumn in Japan known as Aki. The autumn foliage is classified with two different terms: Koyo and Momiji. Koyo describes foliage with red and yellow colors, while Momiji specifically applies to intensely red maple leaves that are particularly spectacular during the season and can be appreciated in this Maki-e rollerball.
