Japanese high school students who look for work usually apply through their school. Under the custom of hitori issha sei, one person, one company, the school recommends each student to only one company for a set period after selection begins, and the company asks for a single application.
A 2020 report by a working team of the Ministry of Health, Labour and Welfare gives survey results. 31.8 percent of students said that it would be better to be able to apply to two or more companies at once. Among schools, 74.1 percent wanted to keep the current system.
A labor researcher told Mynavi that more prefectures now allow multiple applications, but that the option is hardly used.
