Here are a few of the animal sanctuaries in Japan. Animal sanctuaries do not seem to be a well-known concept in Japan and a few have started very recently. They are dependent on donations and support from the community. Here we’ve listed known animal sanctuaries as well as some ways to support them. Note they may not be vegan.
