10 Best Things to Do in Ishigaki

A quick, friendly rundown of a bay too scenic to swim in, the island's best shore snorkeling, a manta ray cleaning station divers fly across the world for, Okinawa's highest peak, a preserved buffalo-cart village, and an island that's 90% jungle — a good starting point for a first visit to this subtropical outer island in Okinawa.

Ishigaki packs a genuinely different Japan into a single subtropical island: a bay too scenic to swim in, a manta ray cleaning station divers fly across the world for, Okinawa’s highest peak, a preserved buffalo-cart village a short ferry away, and an island that’s 90% jungle just beyond it. Ten things worth building a visit around, from the reefs and day trips to the wagyu beef and mangoes that make Ishigaki’s table as distinctive as its scenery.

1
See Kabira Bay
Kabira Bay is Ishigaki's signature view, a curve of turquoise water framed by forested hills and dotted with small islands, its coral formations visible in startling detail through the shallows even without diving in. Swimming is prohibited here — the bay has been used for black pearl cultivation since it became the first place in the world to successfully farm black butterfly pearls, and strong currents make it unsafe regardless — so the standard way to see the coral and marine life up close is a roughly 30-minute glass-bottom boat tour, departing every 15 to 20 minutes with no reservation needed. A short walk along the beach path leads past a pearl jewelry shop explaining the cultivation process, an easy add-on before or after the boat ride.
Glass-bottom boats: roughly 9:00 AM – 5:00 PM; around ¥1,000 per person912-1 Kabira, Ishigaki 907-0453

Snorkel Yonehara Beach
Yonehara Beach offers some of the easiest reef access on the island, with coral visible just a few meters offshore and a wide range of fish, sea snakes, and the occasional sea turtle reported close to the sand — a genuine draw for snorkelers who'd rather not book a boat tour to see marine life. Timing matters more here than at most beaches: the coral sits close enough to the surface that low tide can make swimming over it difficult or damage the reef, so aim for high tide or close to it. There are no lifeguards or jellyfish nets, and currents in the bay can run strong, so it rewards a cautious, self-sufficient approach rather than a casual dip.

Dive with Manta Rays at Manta Scramble
Off the coast near Kabira Bay, Manta Scramble is a natural cleaning station where reef manta rays gather to have parasites removed by smaller fish, drawing divers and snorkelers from around the world hoping for a close encounter. First discovered by local dive guides in the 1980s, it remains one of Japan's most reliable manta-sighting spots, with encounters possible year-round but concentrated roughly June through October and peaking around August and September. Shallow depth and generally calm, clear water make it accessible to snorkelers as well as certified divers, a rarer combination for a site this consistently productive.
Manta season: roughly Jun–Oct, peak Aug–Sep
4
Hike Mount Omoto
At 525.5 meters, Mount Omoto is the highest point in all of Okinawa Prefecture, and its roughly 6-kilometer trail climbs through dense subtropical jungle — native Ryukyu pine, tall ferns, and small waterfalls along the way — to a summit with panoramic views over Ishigaki and the wider Yaeyama Islands. The hike takes somewhere between 90 minutes and two and a half hours depending on pace and conditions, and the trail can turn slippery and overgrown in patches, so September through November or March through April, outside Okinawa's May–June rainy season, are the most comfortable months to attempt it. It's a genuinely different side of Ishigaki from the beaches — quiet, humid, and green rather than turquoise.
5
Ride a Water Buffalo Cart on Taketomi Island
A roughly 10-minute high-speed ferry from Ishigaki, Taketomi preserves what's often described as the last intact traditional Okinawan village landscape — single-story houses behind coral-stone walls, red-tiled roofs topped with shisa lion figures, and narrow sand lanes designated a national Important Preservation District for Groups of Traditional Buildings. The classic way to see it is a roughly 30-minute water buffalo cart tour through the village, the cart driver often singing along on a sanshin, the three-stringed Okinawan instrument, as the buffalo plods along at its own unhurried pace. Ferries run frequently enough — every 30 to 60 minutes through the day — that Taketomi works comfortably as a half-day trip rather than requiring an overnight stay.
6
Kayak the Mangroves of Iriomote Island
More than 90% covered in subtropical jungle and mangrove forest, Iriomote is the wildest of the Yaeyama Islands and the core of Iriomote-Ishigaki National Park, a UNESCO World Heritage Site since 2021 and home to the critically endangered Iriomote cat, found nowhere else on Earth. The Nakama River's mangrove forest, a designated Natural Monument, is the island's most popular kayaking destination, while Pinaisara Falls — at about 55 meters, Okinawa's tallest waterfall — is usually reached by kayaking up the Pinai River before trekking the final stretch through jungle. High-speed ferries from Ishigaki take 40 to 50 minutes depending on the port, making Iriomote workable as a long day trip, though its size and depth of nature reward staying longer if the schedule allows.
7
Go Stargazing at the Ishigakijima Astronomical Observatory
Home to the Murikabushi Telescope, a 105-centimeter reflector that's the largest optical-infrared telescope in the Kyushu-Okinawa region, the observatory takes advantage of Ishigaki's nearly 300 clear nights a year and its position far enough south to see stars invisible from most of mainland Japan, including the Southern Cross. Daytime visits let you tour the facility and learn about the telescope itself, but the real draw is the reservation-only nighttime stargazing sessions, held Saturdays, Sundays, and holidays and booked by phone in advance. It sits well outside the city center, with no public transport out, so a rental car or taxi is the only practical way to reach it.
10:00 AM – 5:00 PM, last admission 4:30 PM, closed Mon–Tue; ¥400 adult admission; nighttime stargazing by reservation, weekends & holidays only1024-1 Shinkawa, Ishigaki 907-0024

Learn About Angama & Yaeyama Traditions
The Yaeyama Islands maintain their own Ryukyuan language, distinct from the Okinawan spoken around Naha and now classified as severely endangered — one of several ways the region has kept a cultural identity separate from the rest of Okinawa Prefecture. Angama, held during Obon, sends masked figures representing an elderly ancestral couple from house to house accompanied by dancers and drummers, welcomed inside to bless the household in a custom found only in the Yaeyama region. Tsunahiki, a harvest-thanksgiving tug-of-war held after Obon, and the Ishigaki Island Festival, the island's largest annual event held the first weekend of November, round out a local calendar that runs on its own distinct rhythm from the rest of Japan.
Angama: during Obon (mid-Aug, dates shift yearly); Ishigaki Island Festival: first weekend of November

Eat Ishigaki Beef
Ishigaki beef comes from purebred Japanese black cattle raised for at least 20 months within the Yaeyama district, each animal tracked with a full production history certificate, and it reached international attention when it was served as the main dish at the G8 summit in 2000. Its fat is prized for melting at a lower temperature than most wagyu, giving it a texture that dissolves almost immediately rather than requiring much chewing, and it turns up across the island as yakiniku, steak, and in gyu-jiru, a simple, deeply savory beef soup that's closer to everyday Yaeyama home cooking than a special-occasion dish. Restaurants around Ishigaki City range from casual yakiniku grills to higher-end steakhouses built specifically around the local beef's reputation.
10
Try Okinawa's Famous Mangoes
Okinawa Prefecture is Japan's largest mango-producing region, and the Irwin variety grown here — deep red-skinned, intensely sweet, and far juicier than most mangoes sold in mainland Japan — is treated as a genuine luxury fruit, sold in gift boxes at premium prices during its short season from mid-June through mid-August. Ishigaki's warm, sunny climate suits mango cultivation particularly well, and the fruit shows up beyond the fresh form too, in soft-serve, smoothies, and sweets sold at cafes and roadside stands across the island through the summer. Outside the short growing season, mango-flavored products remain widely available even when the fresh fruit itself isn't.
