The city's Bureau of Waterworks has made strides in purifying and conserving water, meeting demand, upgrading pipelines, and preparing for earthquakes. In 1898, Tokyo, Japan, modernized its then 300‐year‐old water supply system by building a slow sand filtration plant. The modernized system has come a long way and is celebrating its one hundredth anniversary in 1998. This article highlights the triumphs and tribulations Tokyo has faced over the years in delivering drinking water to its citizens. It covers the development of the dams, reservoirs, and rivers used to secure water; Tokyo's Bureau of Waterworks; efforts to conserve water; upgrades to the distribution system; and emergency preparations for responding to earthquakes.
