Residents in Kawasaki, Kanagawa Prefecture, and Ikoma, Nara Prefecture, are spooked after finding money and gift certificates mysteriously left in their mailboxes.

From March 11 to 12, envelopes containing gift certificates were found in the mailboxes of 30 homes in Kawasaki. The monetary value of the certificates ranged from 5,000 yen to tens of thousands of yen per home. Whoever left them did not leave their name.

The Kawasaki Rinko Police Station is treating the gift certificates as lost-and-found items, and are looking at security footage and checking the certificates' serial numbers to try to find out who left them.

Meanwhile in Ikoma, a total of some 760,000 yen in cash was put into the mailboxes of 30 residences at an apartment complex from March 20 to 21. The cash included coins wrapped in flyers and bills. Then, on the morning of March 22, a shop owner on the first floor of the complex contacted police to report they'd found a 1,000 yen gift certificate when they opened the store shutter.

According to the Ikoma Police Station, the greatest amount of money found at a single residence was 137,000 yen. They say that over half the residents have waived their right to accept a reward from whoever left the money should they appear to reclaim it. Among the reasons given was that the situation is "creepy."
