変な家 (Henna ie) is a collection of short horror stories about houses with strange and uncanny floorplans.

The book has four chapters, each of which takes the form of a series of conversations between the narrator, their architect friend, and various people who have seen the houses in person. The first three chapters explore three different houses with extra rooms and mystery spaces, and these explorations are liberally illustrated with diagrams in which certain sections of the floorplan are highlighted and annotated to clarify the text.

Each of these first three stories is like a locked room mystery, except the mystery starts with a floorplan from which the narrator gradually builds a story about what sort of upsetting behavior that type of strange space might enable. In the final chapter, it’s revealed that these houses (and, presumably, many more like them) are all connected to an old and wealthy family with a terrible secret.   

I flew through this book and loved every page. The conversations are easy to follow; and, thanks to the diagrams, the spaces are easy to visualize. I enjoyed the slow build of the overarching mystery, and the revelations about the bizarre family at the center of the strangeness were beyond anything I expected.

It’s worth noting that the first story in this book was originally written as a script for a twenty-minute video on YouTube, which you can find with English subtitles (here). There’s also a manga adaptation. The first three chapters, which form a complete story, have been scanlated and are available to read (here). And finally, I’d like to share a more substantial review posted on one of my favorite book blogs (here). I’ve got my fingers crossed that this strange little book (and its sequel, which is rumored to be even better) will somehow find its way into English translation.
