The Self‐Identified Stage of Recovery (SISR) is a two‐part scale assessing both the stage of recovery (SISR‐A) and the component processes of recovery (SISR‐B) for people with mental illness. This study aimed to develop a Japanese version of the SISR and to examine its reliability and validity. The Japanese versions of the SISR‐A and SISR‐B were developed through focus group cognitive interviews and the translation–back translation procedure. A cross‐sectional questionnaire survey was conducted of 223 participants who had long term mental illness, were aged 20 years or older, and currently living in communities and inpatient ward settings; 59.2% were males and the average age was 47.6 years. The questionnaire also included the 24‐item Recovery Assessment Scale, Herth Hope Index, Empowerment Scale, and Resilience Scale. Cronbach's alpha coefficient, intraclass correlation coefficient, and weighted kappas were generally fair to high, and the SISR‐A and SISR‐B scores were positively correlated with other relevant scales. This study supported the reliability and validity of the Japanese versions of the SISR‐A and SISR‐B among people with long term mental illness in Japan.
