Abstract
In the Shikoku Mountains, during a study of bats (Murina ussuriensis) with artificial shelters, I once observed a Japanese dormouse (Glirulus japonicus) occupied it in daytime. I also found circumstantial evidence of the dormice using the artificial shelters. One is that stripped plant barks were brought into a small room of the artificial shelter, and another is that the material of the artificial shelter (hemp) was partially untied to fibers. These findings suggest that the artificial shelter has a potential to study wild dormice without using nest boxes.
