Abstract: This study aims to cross-culturally adapt the Yonsei Lifestyle Profile (YLP) to a Japanese version of YLP (YLP-J) for older Japanese adults. We translated YLP to the YLP-J using a formal forward–backward translation method. Subsequently, we investigated content validity using the Delphi expert method to assess the multifaceted lifestyle of older Japanese adults. A total of 11 health-related experts participated in the panel, and opinions were collected through 61 closed questions on item relevance and linguistic relevance. Based on the responses, sum, average, standard deviation, content validity ratio (CVR), stability, convergence, and consensus of each item were obtained. As the results of the first Delphi, 43 and 25 questions did not meet the CVR in linguistic and item relevance, respectively. We modified the item questions according to the comments of the expert panel. According to the results of the second Delphi in linguistic relevance, the mean values of CVR, stability, convergence, and consensus were 0.92, 0.17, 0.39, and 0.77, respectively. According to the results of the second Delphi in item relevance, the mean value of CVR, stability, convergence, and consensus were 0.93, 0.16, 0.39, and 0.80, respectively. The content validity of the YLP-J was examined so that the YLP tool could be applied to the linguistic and cultural context of Japan. It is expected that the YLP-J will be a useful tool for improving the health and quality of life of older adults in Japan.
