Attracting fishermen has become one of the critical challenges to maintain a basic fisheries production system. Therefore, institutions in Japan have been introducing courses, such as fisheries techniques, to attract students to this industry. The aim of the present study is to identify effective methods of developing job training systems to attract more fishery workers to the industry. The current job training courses for becoming a fishery worker are analyzed, and the results indicate that methods of teaching fishery techniques have made progress. Three job-training patterns were identified in the analysis. Pattern 1 was to continue to work in the industry, Pattern 2 to abandon work in the industry, and Pattern 3 to quit the job training prematurely (Pattern 1 (60%), Pattern 2 (17%), and Pattern 3 (23%). The analysis results suggested that providing trainees with sufficient explanations concerning work content included in the training is crucial to enhancing training efficiency. In addition, providing opportunities to learn about other types of fisheries is an effective approach to broaden knowledge on the main type of fishery being studied.
