If you tightly weave the correct shapes of colored squares, it looks like it is moving gently and rhythmically. The Ichimatsu pattern looks as if life itself is blowing through it. Ichimatsu pattern was named after Ichimatsu San, a kabuki actor from the Edo period, who appeared gracefully in white and red costumes. Especially women started wearing it proudly. It was once called the stone tile pattern, but renaming it to Ichimatsu pattern made it more popular. Even today, in the manga 'Demon Slayer,' the protagonist's green and black checkered design transcends the era and remains beloved by many.
