Where can you find the largest system of limestone caves in the Tokai region? Just a short trip from Gujo city in Gifu Prefecture! Venture into what's known as the Otaki caves, and you can take a walk through over 700 meters of the two-kilometer-long tunnels. With a low temperature of around ten degrees Celsius, the Otaki caves are a perfect way to beat the summer heat as you take in the limestone formations with whimsical names such as the "Decorated Cake," as well as seeing the tallest underground waterfall in all of Japan.
