The Osaka child abandonment case was a case of child abandonment involving two abandoned children in Osaka, Japan.
 It occurred in late June 2010 when Sanae Shimomura, a 23-year-old Japanese single mother in Osaka, sealed the door of her apartment shut, abandoning 3-year-old daughter Sakurako Hagi and 1-year-old son Kaede Hagi inside.
 Neighbors heard the children crying over many weeks until it suddenly subsided, but did not think anything more of this than simply children in a bad childhood phase.
 Since Shimomura did not come to work for several days, a colleague went to her place and noticed a strange smell beyond the door.
 When the police entered the apartment, they found the two children dead.
 Social workers had attempted to stop by the apartment several times over the course of the children's confinement, but never found anyone home.
 The apartment was in a lively, populated area, but nobody knew that the children were confined.
