Harumi Wharf Park, where you can see the Rainbow Bridge in front of you, is far away from the hustle and bustle that you can't imagine in Chuo-ku.
There are many families who have BBQ and picnics, but it is not so crowded and it is a good secret place.
By the way, today, a photo session for cosplayers is being held at Harumi Wharf, and it seems to be a mecca in this area.
