River Niyodo
No.1 water quality in Japan
(according to the survey by Ministry of Land,
Transportation, and Infrastructure in 2014 &
2015)
Why Niyodo So Transparent?
1. 75% of Shikoku island is forests
Forests hold rain water and purify rivers
2. Shikoku is attacked by lots of typhoons
Torrential rains purify rivers
3. Runs from high place to Pacific Ocean
Steep angle makes the speed of flow
fast and avoid stagnation
River Niyodo
Right after typhoons attack Niyodo,
preferably on a beautiful sunny day --
-- That’s the best timing to enjoy
seeing River Niyodo
