Ryusendo Cave龍泉洞


This massive limestone cave is one of Japan’s three largest, and is designated a National Natural Monument. The cave is over 5,000 meters long overall, and hosts eight underground lakes that are among the clearest in the world. The color of the water, called Dragon Blue, is astonishing and the mystical sight is worth visiting. A 700 meter walking route in the cave and three of the eight lakes are open to the public. One section of the trail is barrier-free, with full wheelchair access. The limestone filtered water has been named one of Japan’s top 100 waters, and is available to drink at the cave entrance.

          Iwate Main Areas


          A northern Tohoku prefecture promising peace and quiet, Iwate is sparsely populated, replacing people with snow-capped mountains, history-rich sites, and fields of crops that are to thank for the region’s delicious local cuisine. Meander along the three-city Golden Route, where you’ll visit the grand Buddhist temples of Hiraizumi and the Tono folk villages before tasting the three famed noodle dishes of Morioka.
