The Sugamo child-abandonment case (巣鴨子供置き去り事件, Sugamo kodomo okizari jiken) was a situation uncovered in 1988 in Tokyo's Toshima Ward. It involved a mother of five children who abandoned the four surviving young children for months, resulting in the death of one. The names of the children were never released, but were referred to simply as Children A, B, C, D, and E. The incident was covered extensively by both Japanese and international media, and was later the basis of the 2004 drama film Nobody Knows.[1]
