From DrCoke at MangaHelpers:

This manga contains short stores of the author's own paranormal experiences dealing with ghosts, apparitions, and other encounters of fantastic nature. In this volume, she covers a few of her more recent experiences during her travels across Japan, whether for leisure or for business. Many of the stories revolve around the history of the land or hotels where she stays. Some of her stories may incite chills down your spine, while others can be more comical and/or lighthearted.
