At the furniture maker Akiyama Mokkō, training takes eight years: one year as a trainee, four years as a decchi, an apprentice, and three years as a craftsman. Apprentices of both sexes shave their heads. During the apprentice years, they may not use a mobile phone for private matters and may not date.
Training rests on the Shokunin kokoroe sanjū kajō, thirty rules for craftsmen, which apprentices recite.
