If ever out in Okutama area, don't miss out on a chance to visit the largest cave in the Kanto region!
Nippara Limestone Cave was formed during the Palaeozoic Era about 250 million years ago, and extends over 1,270 metres (800 is accessible to the public). It is kept at around 11 degrees centigrade, so make sure to bring a jacket if you get cold!
The cave has been a sanctuary for religious pilgrimage since the Edo period, with many Buddhist statues with offerings and numerous stalactites and stalagmites.
My favorite part of the cave was the main chamber that was lit up with LED lights.
Getting out of the cave will require some endurance as you will have to take a bunch of stairs to get out. We went on a week day so we were the only ones in there, but I have been told it can get crowded during the week! Just remember to watch your head and use inside voices (don't want to wake up Batman right?).
One can easily spend about 40 minutes in here, so its a great pit stop if you are every out in the area!
