About Rototo: RoToTo's socks are produced at a factory on Koryo Town, Nara Prefecture, which boasts the largest production of socks in Japan. They work with craftsmen and discuss "manufacturing" at the site (factory). They use a rare special knitting machine, which is limited in number in the world, an old fashioned knitting machine that has not been computerized, and a state of the art knitting machine. They will make one sock through many fine adjustments while talking directly with the craftsmen. RoToTo socks can only be completed when the knitting machine, thread, and people are united.
