This is the book "Raccoons Across the Sea: The Path of a Popular Creature." The author is Gen Asano (veterinarian). It explains why raccoons, whose import as pets surged due to the TV anime "Rascal the Raccoon," came to be called "pests" in Japan. This book covers their ecology, how they came to Japan, the damage they've caused in various areas, and the measures taken to address the problem. Through the issue of invasive species, it explores how we should interact with wild animals.
