Haginochaya Naka Park is a city park in the Airin district of Nishinari Ward, Osaka, next to the Nishinari police station, and is known as "Square Park." It has recently been renovated, making it brighter and more open, with a large slide, hand-washing stations at different heights, and restrooms. The park is surrounded by a tall chain-link fence with open entrances, and meal service takes place during the day and evening. It is a space where homeless people and elderly people stay, so the atmosphere can feel heavy depending on when you visit.
