In Episode 7 of Chuunibyou demo Koi ga Shitai Ren, Shinka and her friends are on a school trip in Kagoshima. They see a statue of someone called Saigo-san. One of the friends complains that he doesn't have his dog, and Shinka tells her that he doesn't have a dog in Kagoshima.
Later, they find a dog so they can hold it and take a picture in front of the statue.
Interestingly, Saigo-san appears to have European features. I know that Kagoshima is on the island of Kyushu at the far south of Japan. The south hosted a Dutch enclave for years after the foreigners were expelled from Japan under the Tokugawa shogunate. I assume he's some kind of historical figure, but who is he and what's the deal with the dog?
