The Three Domains of Disgust Scale (TDDS) measures disgust sensitivity in three areas—pathogens, sexuality, and morality — postulated from an evolutionary-adaptive perspective. Although the scale has been translated into Japanese, its validity and reliability have not been verified in Japan. This study aimed to examine the validity and reliability of the Japanese version of the TDDS. In Study 1, we conducted a web-based survey of 1,030 participants (515 males, 515 females) to confirm the scale’s factor structure and to examine its concurrent validity and internal consistency. The results indicated that the sexual and moral disgust subscales were valid and reliable; however, some problems were found with pathogen disgust. In Study 2, 108 undergraduates (22 males, 86 females) were surveyed twice at 2-week intervals to examine the scale’s test–retest reliability. The results showed that the measures had high test–retest reliability. The validity and reliability of the scale are discussed on the basis of these measures.
