The place is lovely and beautiful for several reasons. If you walk along the gate you will reach a small island-like place from where you can view your surroundings well. There are some old stone made chairs and tables under the trees to sit and rest, and a big stone memorial with Japanese writing, I can't read. You can get close to the water from here as there are some stairs that go straight to the water. Besides, you will find Arakawa museum of Aqua, a place for picnic and bar-b-que, baseball field, cycling and jogging trails very near this watergate. To enjoy it most please come to weekdays instead of holidays to avoid crowds. This place is really popular.
