Benches or other seats in parks or public spaces are generally fine to eat, although there are some places where eating or drinking is forbidden, so it's a good idea to check in advance. But you should try and avoid any behavior that might bother people around you, such as occupying a place for a long time during a busy period, or being noisy close to a residential area. It's also good to note that theme parks such as Tokyo Disney Resort usually don't allow you to bring your own food or drink into the park, but there are places to buy food on site and you are allowed to eat any food you bought as you walk around the park.
