The Japan Water Agency is now constructing
Koishiwaragawa Dam in Asakura City, Fukuoka Prefecture, in Kyushu. Its dam height is going to be 139m,
the highest in Kyushu when completed. Huge machines are moving around at the construction site. So the site tour will provide you with a very rare chance to watch such construction site with your own eyes. In November 2018, the dam site celebrated its tour participants reaching 1000. In January next year, four tours (twice each day) are to be planned on
12 and 26 in January. If you are interested in this tour, please make your reservations as soon as possible. The reception of your reservation is only accepted on weekdays from 9:00 to 16:00.
Please be reminded that the reservation reception, briefing in advance of the tour, and the guided tour are all conducted in Japanese only.
