The purpose of this study was to validate the 7-item long-term mating orientation scale (LTMO) as translated into Japanese. Two samples of Japanese adults (N=2000; 50.0% male; Mage=40.9 for the first survey; N=300; 54.7% male; Mage=42.4 for the second survey) completed a web-based questionnaire, including the Japanese translation of the LTMO. The results showed that the psychometric properties of the Japanese LTMO scale were comparable to those of the original English version. The scale had adequate reliability based on Cronbach's α and McDonald's ω. Convergent validity was demonstrated by the correlation between the LTMO scores and related variables: human life history strategies, short-term sociosexual orientation, attitude to infidelity, romantic attachment style, and so on. The translated scale provides a valid and reliable instrument in Japanese that measures human mating strategy.
