There are many unusual foods in Japan that are named after famous countries or cities.
For example, ”the Harajuku Dock” is often seen in other regions, but I have never seen it in Harajuku.
This “Taiwanese minced cutlet” is no exception and does not appear to be a local food.
Many Japanese people enjoy it as a joke as long as it is not illegal, and I am no exception.

This is a minced meat cutlet containing chili peppers and chives.
It’s Nagoya style, so it has a strong flavor.
Not recommended for people who don’t like spicy food, but perfect as a beer snack.
It doesn’t seem like it’s sold every day, but if you’re lucky, you might be able to buy it at the store linked below.
