The origin of the clock's name, with sly touch of humor, comes from the Japanese way of telling time. In Japanese, one reads 5 minutes as "go(five)-fun", 10 minutes "ju(ten)-pun", 15 minutes "jugo(fifteen)-fun" etc. Developed in conjunction with a senior researcher at Japan Montessori Institute, the clock was designed to promote understanding of minutes, hours and time for children, yet the simple design and beautiful, natural materials allow it to work in various interior settings.
