The southernmost cave in Japan, created by coral reefs over 200,000 years ago. It's 3.2 kilometers long in total, making it the largest cave on the island, and 660 meters are open to visitors. It's known for its illuminations in the Senkyo area of the cave, but a variety of features throughout the cave are also of interest.

八重山鍾乳洞
An ill-maintained park with a high entrance fee, there is an unmanned gate where you can purchase a ticket. While the nature part of the park is impressive, overgrowth can make it difficult to see everything. It is sometimes compared to an experience of wandering into the mountains which is appealing to those who prefer a less curated experience. There are two caves on site. Visitors have noted that lighting in the cave may or may not be turned on and it may be sporadic inside the cave, so bring a good flashlight if you are committed to entering. You should not expect to find any employees, so you can explore freely but no one can assist you if you need help. While the site does not have broad appeal, it does have some cult appeal among those who enjoy exploring abandoned or semi-abandoned parks, as well as those who prefer to see local flora in a more wild and unmanicured state. In addition guided tours of the limestone caves allow you to see parts of the cave that are closed off to regular park entrants. Advance reservations are required for these tours.
The most common reason foreigners come here is due to confusion between this cave and the Ishigaki Stalactite Cave, which is larger, safer, fully-staffed and is the cave that is prominently featured in tourist ads. They are located near one another but along two different offshoots from the main road, hence the confusion. Refer to the listing "Ishigaki Stalactite Cave" for information about the other cave.
具志堅用高記念館
A World Champion boxer during the 1970s-1980s who held the WBA light-flyweight title for 6 years from 1976 to 1981. He retired after losing the title and is most known today as a guest on variety shows. The museum focuses solely on his boxing career, with belts, trophies, gear, etc. from each of his boxing matches. Over a recreated boxing ring on the second floor, a television plays his full boxing matches.
八重山平和祈念館
A small museum outlining life on Ishigaki during World War II with special attention given to the prevalance of malaria on the island at the time, how the war pushed the disease to epidemic levels when the locals were evacuated into the mountains and aid was cut off, and the eradication of malaria from Ishigaki and the Yaeyama Islands by Americans after winning the war.
バンナ公園
A large nature park home to a variety of unique plants and wildlife. There are a handful of lookout points from where you can see most of the island, rest pavilions, monuments, and playgrounds. Seishika Bridge, which runs over the largest lake in the park, is also a scenic point. There is a nearby lookout from which you can view and take pictures of the bridge.
宮良殿内
730記念碑 Nana-san-maru kinenhi
This black rock mounted on a concrete plinth is not much to look at, but given its central location in downtown Ishigaki next to the port and the beginning of Route 390, the mysterious number warrants an explanation: it commemorates July 30, 1978, the day when Okinawa switched from driving on the right (like the US) to the left (like the rest of Japan). The 730COURT shopping mall is also nearby.
