Objectives The aim of this study was to validate the Japanese version of the job crafting scale (JCSJ). JCS measures four independent job crafting dimensions, namely increasing structural job resources, decreasing hindering job demands, increasing social job resources, and increasing challenging job demands. Methods The translated and back‐translated JCS‐J questionnaires were administered online to 972 employees of a Japanese manufacturing company. The data were then divided into independent explorative and confirmative samples. Exploratory and confirmatory factor analyses were performed to evaluate the factorial validity of JCSJ. The relationship with potential consequences of job crafting (e.g., job demands, job resources, and psychological well‐being) was investigated to evaluate construct validity. Internal consistency was examined to evaluate the reliability of the four JCSs. Results An exploratory factor analysis extracted a five‐factor solution. Decreasing hindering job demands was further split into two separate dimensions supporting a five‐ rather than four‐factor structure. A series of confirmatory factor analyses revealed that the modified five‐factor model that allows covariance between items fits the data best. Construct validity was generally supported by the expected correlations of each job crafting dimension with each corresponding job resource (+), job demand (+), and psychological well‐being (+). Cronbach's α coefficient was sufficient for each of the four dimensions of job crafting (α ranged between 0.76 and 0.90). Conclusions This study confirmed that JCS‐J is an adequate measure of job crafting that can be used in the Japanese context.
