Story summary

The home village near Tokyo's Narita Airport where Unit 731, responsible for biological warfare in Japan, was headquartered is currently being demolished to expand the airport. Demolition began in August 2026, approximately 5km (three miles) from the southern perimeter fence of the main runway. Notably, among the buildings flattened includes the family home of Ishii, the unit's commander. The expansion project is drawing attention due to Unit 731’s controversial history involving human experimentation during World War II.
