Springs of Okazaki, Aichi Prefecture (June 8, 2021)
Clear Water Where Fireflies Live: One of Japan’s 100 Best Waters
Torigawa Firefly Village (Torigawa Hotaru no Sato) in Okazaki City has springs scattered all around. Together they have been selected by Japan’s Ministry of the Environment as one of the “Heisei 100 Best Waters” under the name “Torigawa Firefly Village Springs.” In a popularity vote, they were ranked No. 1 in Japan as the best water in a hidden, remote place!
The most famous spring is Enmei-sui (“long-life water”). The photo shows Ubuyu Falls, about 500 meters from Enmei-sui.

When we visited in June, fireflies were flying, and we also stopped at the Firefly School (no photos).



We happened to meet a local resident who told us that NHK would broadcast a program about the fireflies and the spring water on June 20, 2021.
The water is soft and delicious. We used it to make coffee.
Hydrangea Village
We also visited the nearby hydrangea village, where the flowers were in full bloom in shades of blue, purple and pink.















Okazaki also has a temple known for prayers to ward off cancer.
