Movement of diversity management (DM) is gradually spreading in Japanese hospitals. However little has been discussed about the effectiveness of DM in organizational ergonomics domains. Hence, this case report aimed to extract the elements of workforce diversities in Japanese nursing workplace. We conducted a semi-structured interview to four nurses with enough career to response the interview. Three were administrative nurses (male = 1, female = 2) and one was non-administrative nurse (male = 1). As the results, twelve elements of diversities with narrative evidences were extracted; (1) Seniority, (2) Career, (3) Age, (4) Gender, (5) Nationality, (6) Role orientation, (7) Employment pattern, (8) License, (9) Personality, (10) Disability, (11) Family, (12) Benefit package. According to their interviews, their workplace has been received the diversities of seniority, career, age, gender, employment pattern, disability, family and benefit package. On the other hand, they regarded the acceptance of license, personality, nationality and role orientation diversities as future issue. These diversity elements may be key points for the practical DM in Japanese nursing organization.
