This book wouldn't have been written had Matsubara Tanishi been more successful as a comedian. Funny how life can be. Long periods between jobs resulted in Tanishi's agent offering him unique stints, which are to live in 'stigmatized properties' (事故物件, 'jiko bukken'). The rest is history, with Tanishi now an established entertainer with a spooky niche. Worry not, for so far he seems to be in good health and successful to boot, hosting his own podcast with guests the likes of Junji Ito and the father of Japanese ghost story, Junji Inagawa.
A property becomes a 'jiko bukken' when a 'bad death' occurs there. What is a 'bad death'? Murder, obviously; suicide, for sure, but also in the increasingly aged and lonely society of modernized Japan, a lonely death that goes undiscovered for so long. This concept is relevant, so much that all real estate agents are required to disclose whether a property is a 'jiko bukken' or not. There's even a website, Oshima Teru, dedicated specifically and only for tracking 'jiko bukken'.
As a book, it actually doesn't stand out that much, but Tanishi does do a good job of storytelling. The Japanese is easy enough to understand for someone with an N2. Enjoyable and unique in its execution.
