Ota is home to Tokyo International Airport, also known as Haneda Airport. Haneda is the busiest airport in Asia.
The Keikyu Airport Line offers a quick connection from Haneda to Keikyu Kamata, with onward connections available to central Tokyo and Yokohama. The train stops running between 12:20am and 5:30am but taxis are still available.
The only thing worth seeing in the area is the Tamagawa River which stretches from Haneda Airport to Kawasaki city and beyond.
A great place for a jog or a bicycle ride with the locals.
Best time to see it is in spring when all the cherry trees are in bloom.
