Osaka is known as a metropolis, but it also has many beautiful parks, and you can enjoy the outdoors from anywhere in the city without traveling far.
Notable among these destinations are Osaka Castle Park, Nakanoshima Park, and Kemasakuranomiya Park (famous for its gorgeous cherry blossoms), all of them located in central Osaka City. If you head to northern Osaka, you can enjoy a bit of hiking among the beautiful waterfalls at Mino Park. Another recommendation for the area is a tour of the Open-air Museum of Old Japanese Farm Houses at Hattori Ryokuchi Park. Also, the Expo Commemoration Park, which hosted the 1970 World Fair, remains popular even now and is loved by both locals and travelers as a destination for picnicking or events. In southern Osaka you'll find the famous Tennoji Zoo, one of the city's leading spots. Also in the south is the world-class Nagai Park, hallowed sporting grounds for many of Japan's athletes.
