I have a hard time getting behind this.
True, I have never been to Tokyo, and Japan is one of the least familiar cultures for east-coast North Americans like me. All I know of it is from movies, the odd documentaries and articles I've seen and read, and second-hand knowledge from friends who lived in Japan or visited the city. But Tokyo remains a real city on planet Earth, inhabited by humans keeping animals as pets, driven by cars and working the technologies I know. The cultural differences are huge, but still very thin compared to how a family of beavers would live, let alone a society shared by intelligent animals
That alone makes me a lot more familiar with Tokyo than Narnia even if I had written it.
