The rapidly aging population in Japan constitutes a problem as public health expenditure is expected to increase. At the same time, the working part of the population is decreasing straining the health insurance scheme. Since the workplace is a setting that influences a large part of the adults for a long part of their lives, workplace health promotion has potential to improve the situation. This paper examines how workplaces in Japan are used for health promotion. Deductive content analysis is used to examine how workplace interventions are examined in the research literature. The findings suggest that there is considerable variation in workplace health promotion in Japan.
