In order to prevent the spread of coronavirus (COVID-19), various facilities around Tokyo may change their operating days or hours. In addition, some events may be canceled or postponed. Please check official facility or event websites for the latest updates and information.
Since 1653, the Hamura Intake Weir has been supporting people's lives by supplying water from the upper reaches of the Tama River. It is conveyed from the weir to the Maruyama and Yamaguchi Reservoirs. During heavy rain or typhoons, the weir is opened up—this allows the water to flow through, which helps to control the rising water level.
Around 200 cherry trees line the banks of the river, making this a popular place to see blossoms in spring.
For updated information on opening hours, closings, prices, and more, please check the official website or ask the facility directly.
