In early January at about 8 p.m., a 17-year-old who works at Naniwa de Sanpo (A Walk in Naniwa) in Osaka's Namba district stands outside a convenience store with a luxury bag slung across her shoulder.
Moments later, a man in a suit who appears to be in his 30s appears and greets her. The girl, who did not reveal her identity, walks off with the man. Several minutes later, the pair cautiously observe their surroundings before discreetly slipping into a love hotel.
About an hour later, they exit the building separately. The girl returns to the convenience store where she waits outside for a rendezvous with another man.
