A 518-meter-long cave that maintains a temperature of 15 °C (59 °F) all year round. The cave has many stalagtites and stalagmites, some of which have been noted and named for their unique appearances, such as "The Giant's Foot" (巨人の足) which really does look like a giant leg and foot. It also contains fossils and there are trout in the river that runs through it. The pathway is flat and has no stairs, so it's known for being a good cave for families with younger children.

大谷吉継の墓 Ōtaniyoshitsugu no haka
One of the westernmost memorial markers in the town, this spot marks both the encampment and final burial site of Ōtani Yoshitsugu, one of the Western Alliance's main commanders. When he realized the defections of Kobayakawa Hideaki and others and the increasingly small likelihood of Western victory, he committed seppuku, or ritual suicide. Best reached by bicycle (although it is within walking distance, it just takes longer to get to than most other sites), but the final stretch up the mountain must be walked.
美濃国と近江国との国境
A stone monument marks the border between the former Omi Province and Mino Province. On either side of the border, there are also markers that give the modern borders of Shiga Prefecture and Gifu Prefecture.
関ケ原ウォーランド
While it's not a historic site, War Land is an open-air recreation of the Battle of Sekigahara. It includes encampments with the famous leaders marked so you can take pictures with your favorites. They also have samurai armor rentals for an additional fee so you can take pictures in the battlefield as a fighter. Armor rentals are not available in the summer due to the high risk of heat stroke. Just outside of War Land, they often host other events, such as summer umbrella (hanagasa) displays and cosmos flower viewing in the autumn.
今須宿問屋場
Toiyaba were places in post towns where Daimyo and officials went to get or exchange horses, personnel, and perform various administrative tasks. They existed in every post town, however very few Toiyaba exist today. The Imasu-juku's Toiyaba is Gifu's sole remainder.
