The Trypophobia Questionnaire (TQ; Le et al., 2015) measures proneness to trypophobia, which refers to disgust for a cluster of objects. We developed and psychometrically tested the Japanese version of the TQ (TQ-J). The TQ-J was completed by 315 adults. Convergent validity was examined using ratings of discomfort induced by trypophobic, neutral, or unpleasant images. Discriminant validity was examined using the trait version of State-Trait Anxiety Inventory (STAI-T). Two weeks later, participants recompleted the TQ-J. Like the TQ, the TQ-J showed a one-factor structure, internal consistency (α = .95), and test-retest reliability (r = .77). TQ-J scores correlated with discomfort ratings for trypophobic (r = -.61) but not neutral (r = .07) images. Unlike the TQ, TQ-J scores correlated with the rating for unpleasant images (r = -.31) and the STAI-T (r = .26). The TQ-J may require further validation, considering the influence of culture and different kinds of disgust.
