Workers in this job say high school is common. From job tag's survey of people in each job, who could give several answers. It shows what workers see as common, not how many workers hold each level.
How to become one
No particular education or qualification is required to start. People usually go into this job straight after finishing high school or similar. There is also mid-career recruitment from other jobs. Most new school leavers find jobs through their school or Hello Work (public employment service). Mid-career hiring is done through Hello Work, newspapers and job advertisements. A high level of skill is needed, and knowledge of mechanical engineering is an advantage, but building experience on the job is what matters most. There are many machines and tools to learn to use. Training usually starts on general-purpose machine tools with material and part machining to learn basic cutting skills, before moving on to NC (computer-controlled) machine tools such as NC milling machines and machining centres. In small factories, one person often does most of the die-making work, so you get experience of every stage. In larger workplaces the machining is divided up, and you start with basic machining tasks. A related qualification is the die-making technician grade of the ginou kentei (national trade skills test) set by the Ministry of Health, Labour and Welfare, which is valued as proof of skill. You need the patience and persistence to see a job through to the end. Each die is made to order, so the work is not about making the same thing by a set process: you need curiosity about new things and the ability to come up with ideas.
