Chikan (ç—´æ¼¢, ãƒã‚«ãƒ³, or ã¡ã‹ã‚“) is a Japanese term meaning "molester" or "pervert." The term is frequently used to describe people, nearly always male, who take advantage of the crowded conditions on the public transit systems to touch people, primarily females, sexually. Although women on crowded trains in Japan are the most frequent targets of chikan, sexual predators in Japan take advantage of other situations as well.
