Daruma dolls, which have been popular among people as lucky charms, are modeled after Ambassador Daruma, known as the founder of Zen Buddhism. There is a story that after nine years of intense meditation, his limbs rotted and disappeared. As the founder of Zen Buddhism, his attitude of taking on new challenges and devoting himself to one thing overlaps with Koga's attitude as an artist who strives to create new value called ``anti-wabi-sabi.'' The countless studs that cover the Daruma doll strengthen the meaning of the Daruma doll, which symbolizes a rebellious spirit and that it always gets up.
