Tell us about the "hidden side of Japan" that you know.

A hidden place where the stories have been lost, fragments of concealed incidents.

Abandoned villages that have disappeared from maps, countless unsolved mysteries buried in the dark corners of history.

The depths of unsolved cases, the sites of mysteries that refuse to be solved.

We are seeking information on "forbidden places" that we, Nanajapa, would like the two of us to infiltrate and investigate.
