One of the largest and most famous caves in Japan. The first 400 m of the 1000-m limestone cavern are open to the public. Stalactites and stalagmites abound, and the centerpiece is a 30-m underground waterfall. This cave stays about 15°C year-round, making it a great place to cool off during the sweltering summer heat.

龍潭寺
The main hall here has "nightingale flooring" much like Nijo castle in Kyoto. When walked on, the flooring makes subtle bird sounds to warn of intruders. The garden here is a nationally designated scenic beauty. On the south side of the temple is a well which belonged to the founder of the Ii clan in the early 11th century.
方広寺
This Zen temple, nestled among pines, sakura, peach, and other things, was established in 1377 and is the home of the Rinsai Sect, housing three much-revered Buddha statues. With over sixty halls, it is one of the biggest temples in the Tokai area. The small Shichison Bosatsudo is the oldest wooden building in the prefecture and a fine example of 14th century Japanese architecture. Visitors can walk through the buildings- no shoes allowed.
長楽寺
This temple, built at the start of the Heian era, has a charming garden with plum trees, and is especially beautiful with the change of the leaves in the fall.
三岳城跡, Mitake Jouseki
A somewhat strenuous hike will bring you to the ruins of a castle built atop 467-m Mt. Mitake in 1340 by the Ii Clan.
気賀関所
This restored checkpoint along the Princess Road was established by Tokugawa Ieyasu in 1601. Now dressed with authentic props, visitors can get a glimpse of how tightly controlled travel in that era was. The gate is especially impressive.
寶林寺
Established by an invited Chinese Zen master in 1667, this temple is a fine example of late Ming Dynasty Chinese architecture. The Buddha hall and the priest's residence are designated National Important Cultural Properties.
