If you¡¯ve taken a rush-hour train in any major Japanese city, you¡¯ll likely had the experience of ÉíÌåµÄ½Ó´¥ (shintaiteki sesshoku, physical contact) ¡ª which can lead to flared tempers.

For the past few months, however, social media has been abuzz with more serious cases of intentional ÐnÍ» (²õ³ó¨­³Ù´Ç³Ù²õ³Ü, crash/collision) and Ìåµ±¤¿¤ê (taiatari, bodycheck/body slam) assaults by men in station precincts. In such cases, the victims of such incidents are most often Å®ÐÔ (josei, women), while the attackers are usually ÖÐÄêÄÐÐÔ (ch¨±nen dansei, middle-aged men).

These Ìåµ±¤¿¤ê happen so frequently that the men involved have acquired a nickname: ¤Ö¤Ä¤«¤êÄÐ (butsukari otoko, bumping man) and ¤Ö¤Ä¤«¤ê¤ª¤¸¤µ¤ó (butsukari ojisan, bumping middle-aged man).
