Jonanjima Seaside Park is on Jonajima, which is an artificial island to the north of Haneda Airport. There is also a camp site in the park, allowing visitors to enjoy outdoor activities as well as the night view of Tokyo.
As Jonanjima is located at the very edge on the west side of the Tokyo Bay area, you can enjoy a panoramic night view of a large area from the Tokyo metropolitan area to Chiba, located across the sea, and Haneda Airport.
It is one of the best viewing locations, as you can see Tokyo Tower, the Rainbow Bridge, Shibaura, Odaiba in the direction of the Tokyo metropolitan area, as well as the TOKYO SKYTREE on the right side.
In contrast with the glimmering night view of the metropolitan area, to the south of the park, the illumination of Haneda Airport is dotted with airplanes passing by over the head with an impressive sound.
Although you can enter the park 24 hours a day, Jonanjima prohibits any non-related vehicles from entering from 9:00p.m. to 6:00a.m. Please note that the parking lot for the park is available from 7:30a.m. to 9:00p.m.
There is a bus stop within walking distance, but the last bus departs before 9:00p.m. on weekdays, so please check the timetable before visiting.
