We examined the effects of altruism in daily life and the Big Five personality traits on professional hospitality. A web-based survey was conducted with 208 participants (ages in the 20's to 50's) who have been engaged in hospitality industries. We conducted multiple regression analyses to infer the effects of altruism toward different types of recipients and Big Five traits on scores from the Japanese-style hospitality scale. The results indicated that altruism toward family members and friends/acquaintances significantly affected hospitality. On the other hand, altruism toward strangers did not affect hospitality. The influence of the Big Five traits differed according to the factors of the hospitality scale.
