Tokyo Metropolis Halts Door-to-Door Visits in Historic Baby Swapping Probe
In a significant procedural shift for the inquiry into an incident at a Sumida Ward hospital 68 years ago, officials have communicated their decision to forgo direct contact methods with the subject's family.
The Tokyo Metropolis has formally informed the father of a man involved in a baby swapping case from 68 years ago that it does not intend to conduct door-to-door visits to identify potential birth parents. This decision marks a specific limitation on the scope of the investigation, which was initiated following a court judgment ordering the identification of the original parents.
The inquiry centres on an incident that occurred at a Tokyo Metropolitan Government hospital in Sumida Ward, where a man was swapped with another infant. While the court has mandated the investigation, the administrative body responsible for its execution has opted against the traditional method of canvassing the community to locate the subjects.
According to reports received on 11 May 2026, the Tokyo Metropolis conveyed this decision directly to the father of the man at the centre of the case. The communication clarified that while the investigation remains active, the specific tactic of visiting households to question potential relatives will not be implemented.
The father acknowledged receipt of this information and noted that the investigation is being conducted pursuant to the existing court judgment. He indicated that the decision to avoid door-to-door visits was explicitly communicated to his side, highlighting the constraints placed on the administrative process by the legal framework.
Despite the exclusion of physical visits, the investigation continues under the authority of the court order. The Tokyo Metropolis has not detailed the alternative methods it will employ to comply with the judgment or provided further specifics on the timeline for identifying the birth parents.
This procedural update underscores the complex intersection between judicial mandates and administrative discretion in long-standing cases involving privacy and historical records. The Tokyo Metropolis remains the primary institution overseeing the inquiry, balancing the court's requirements with its own investigative protocols.
