Katsukura is a chain of tonkatsu restaurants. Good tonkatsu. We only tried the one in the Teramachi shopping arcade just off of Shijo-dori, but it was so good that we went back another day and paid extra for a higher grade of pork. The restaurant itself is an oasis of calm in a busy shopping area.
They have a number of locations around the country, including Kyoto, Osaka, Kobe, and several in Tokyo.
