100 Modern Waterworks近代水道百選
About this collection
The 100 Modern Waterworks is a selection of one hundred waterworks facilities chosen in 1985 by the Japan Waterworks Newspaper. Among the many "100 selections," this one is relatively obscure and not well known. Due to its nature as a selection of waterworks facilities, it does not serve as a tourist attraction. Even local residents in selected areas may be unaware of its existence.
Japan's modern waterworks development began in 1887 (Meiji 20), and this selection commemorates the centennial by choosing 100 facilities nationwide. The targets included water purification plants, dams, water sources, reservoirs, and water towers. Selection criteria focused on historical value, scenery, technological excellence, and contributions to the community.
Many facilities are located in rich natural environments, with some overlapping with other selections such as the "100 Dam Lakes." Even without the specialized perspective of waterworks history, visiting these facilities as part of a hike might be enjoyable. However, not all facilities allow public access, so it is advisable to research beforehand. Some are located in mountainous areas, so appropriate hiking gear is recommended.
