How to become one

Often no particular education is required. People rarely become inspectors straight away after joining; they usually move across from manufacturing departments. The qualifications and experience needed vary widely with what is being inspected, from work beginners can do to work where a particular qualification is preferred or some years of experience are needed. Recently, thanks to better measuring equipment, even people with little experience can carry out high-precision inspections, and there is a lot of mid-career hiring. However, for specialist inspections, knowledge of the basics of measurement and food processing is an advantage, and fairly many studied fields such as microbiology, fermentation, food science, or animal or fisheries science at university, or graduated from cookery or food manufacturing courses at a senmon gakko (vocational college). In every case, after joining you deepen your knowledge of food hygiene by taking training such as food safety and hygiene courses given by the health and safety manager, and regularly attending courses and seminars run by public health centres and chemical companies. Each product has set inspection steps and items, but you must also pay attention to efficiency, so you need to build up know-how, such as judging from experience which items deserve more time. Careers can develop by moving from simpler inspections to more difficult ones with experience, or by moving into research and development or product development. After some years you may be promoted to supervisor (sub-leader) and then deputy section manager (leader), and later to management or supervisory posts such as deputy factory manager or factory manager. In that case it is desirable to gain the qualifications that the Food Sanitation Act requires businesses to have: the food sanitation supervisor (by completing a set university course or taking courses from the Japan Food Hygiene Association or the National Meat Training School) and the food hygiene officer (by taking the training course run by each prefecture's food hygiene association or similar). Related qualifications include food microbiology testing technician (Japan Bento Promotion Association), the bacteriological testing skills test and radioactive substance measurement skills test (Japan Food Research Laboratories), and food hygiene instructor (Japan Food Hygiene Association). To improve the quality of your inspection work, it is important to broaden your knowledge of the products you handle, and depending on what you inspect, knowledge of food science, animal science, fisheries science or agricultural chemistry helps. Recently there has also been more focus on managing inspection figures, and knowledge of statistical data management may be needed. Basic PC skills in Word, Excel and similar are also usually required. Inspection involves detailed, set tasks repeated precisely, so you need to keep up your judgement and concentration and be suited to doing the same work quietly every day without getting bored. Because deadlines matter, you also need to work efficiently and in an organised way, and to have the wide view to look over the whole production process and suggest solutions from different angles. The work can involve long periods of standing or working in particular positions, so a certain level of fitness is needed. Visual inspection needs a certain standard of eyesight, and if you need correction you may be asked to wear glasses rather than contact lenses (because a contact lens that falls into a product is hard to find). Some products are inspected by touch or by hearing. You often coordinate and cooperate with others in production and report to or consult supervisors when there are problems, so communication skills are important. You also need to stay composed and respond calmly and properly, and to have the responsibility and integrity to keep customers' trust. To stay in the job for a long time, it helps to be interested in food and to enjoy making it.
