Tonkatsu Tsuruichi is a lunch restaurant in the Matsuyama district of Naha, Okinawa, serving tonkatsu made with Chiba Prefecture Lin SPF pork. The menu includes shoulder loin and rib roast tonkatsu and a katsudon whose bowl stays open, with salt, sauce, and donburi sauce served on the side. During lunch, self-service fried chicken and fish nanbanzuke are available while customers wait. The free fried chicken runs out around 1 p.m., so arriving early is necessary.
