Mysterious Key Boxes in Tokyo Bay Area Rapidly Increasing What’s Their Purpose

Have you heard of the “mysterious key boxes” quietly becoming a topic on social media?

It’s said that unidentified key boxes are installed in several places, including utility poles, in the bay area of Chuo Ward, Tokyo. Who exactly, and for what purpose—? The FRIDAY Mystery Investigation Team promptly rushed to the scene.

Upon arriving at Kachidoki Station, a corner of the bay area, we immediately spotted one nearby. It was attached to a fence next to a towering 58-story condominium. It was black in color, about the size of a palm, and had four dials. We found several others in different locations, all with a similar design.

I spoke to a security guard at a nearby parking lot.

“Every other day, men in suits and women dressed like office workers come to these key boxes and seem to be operating something. I’ve tried talking to them once, and they just said they were doing rounds for their company and left. It’s a bit eerie.”
