This study investigated job satisfaction among nurses in Japan The instrument for measuring occupational satisfaction of hospital nurses developed by Stamps and her associates was used Initial items were reviewed by content experts who were familiar with measurement of work satisfaction among health professionals and nursing practice in Japan Based on the item analysis in the cultural context, several items were reworded or eliminated from the original version Twenty-five items were retained and translated into English by bilingual professionals The questionnaire was administered to 613 nurses Practising in a large, acute-care hospital in a southern part of Japan The results from testing psychometric properties of the translated version of the instrument were satisfactory It may be concluded that nurses in the study were not satisfied but not dissatisfied either On all items, they showed relatively strong commitment to their work However, extrinsic factors such as having little opportunities for promotion or less favourable working conditions appeared to negatively influence job satisfaction in the study The findings support the dual factor theory of Herzberg and also Maslow's theory Considering the lowest scored item, little opportunities for promotion, which reflects the employment system in Japan, administrators, who are usually male medical practitioners, should be made aware of a need for creating clinical ladder opportunities for nurses who would be promoted based on a merit system, instead of the current practice of a seniority system
