You may want to thank Hamura Intake Weir on Tama River for its continued water supply to Tokyo since 1963. The weir takes in a large amount of water and discharges 2 square meters every second. When heavy rain or typhoons bring the water level up, the beams of the weir are removed so that water can flow downstream automatically. The water collected at this dam flows to Maruyama and Yamaguchi Reservoirs.
Hamura Weir is located in a wide open area. Take advantage of the beauty of its vicinity and have a picnic at the grassy area nearby. You can see cherry blossoms here in spring as well.
