It was the longest week of my life and packing for the trip in million-degree heat may have caused a tiny (ginourmous) amount of marital discord, but we did it and it was pretty darn cool.
So we drove the 19 (3-4) hours South to Ryusendo and camped at the camp ground right next to the caves with 4 other families from church. It was a pretty nice facility with grass, a cooking area with running water, clean new bathrooms, and even a coin operated shower. Oh, and some of the largest bugs I have EVER seen. Present company excluded.
The caves were pretty darn spectacular even though the boys were less than impressed. It was super cold inside and their clothes were wet (because it was super HOT outside and we were playing in the water) so they walked in and immediately wanted to leave.
"NO! I DON'T CARE ABOUT ANYTHING IN THIS CAVE!" sigh.
"One of Japan's 3 greatest limestone caves, Ryusendo has a number of underground lakes enriched with water of exquisite features. Sceneries of the lakes, keep the massive volume of water ever quietly, are exposed to visitors when they proceed in a long, narrow, and complex underground path in the giant cave.
The first lake to be encountered in the cave is called "Ryugu-fuchi (pond of Dreagon palace)", known for high level of transparency of water as one of the highest in the world with 41.5m. The third lake has a depth of 98m, and its emerald-like shining water is the highlight of the tour.
Spring volume mounts 17 thousand tons daily in Ryusendo, flowing out into a river. Temperature of this remarkable water is naturally kept at 7～10℃ throughout year. Notably this water is bottled and marketed nationally under brand name "Ryusendo-no-Mizu (Water of Ryusendo)", known also for winning Gold awards in Monde Selection.
It was a great trip despite coming home with 10,000 mosquito bites and a boat load of laundry.
Maybe we'll go camping again someday.
But not someday soon.
