The Japanese word 便 (べん) has multiple meanings, all stemming from the idea of "convenience," "opportunity," "means," or "service." The specific meaning depends on the context. Its versatility makes it a frequently used word in everyday Japanese. The kanji 便 itself is composed of two parts: the radical "亻" (にんべん - "human" or "person") and "更" (こう - "again," "renew," or "moreover").
