Jonanjima Seaside Park 城南島海浜公園

Sea views, picnic facilities, and airplane close-ups

Although it's only half an hour from central Tokyo and even closer to Haneda Airport, the atmosphere of Jonanjima Seaside Park feels like a beachside resort. Situated on the edge of Tokyo Bay, the park features a campground, dog run, barbecue facilities, sandy beach, and a skateboard plaza all within walking distance.

Although you can't swim here, the park's many alternative attractions make a day trip worthwhile. As well as beach-goers, the area is popular with aircraft enthusiasts as it's an excellent vantage point to witness the many airplanes flying into and out of Haneda Airport.
