Yonaguni Island Tourism: 14 Recommended Tourist Spots

Yonaguni Island is the westernmost island of Japan, located only 111 km away from neighboring Taiwan. This small island, shaped like a sweet potato, can be circled in about 3 to 4 hours by bicycle. Rich in nature, the island boasts a unique ecosystem and culture, attracting many tourists from all over Japan each year. This time, we have compiled a list of 14 must-visit tourist spots on Yonaguni Island.

1. The Hill Where Japan’s Last Sunset Can Be Seen

Since Yonaguni Island is Japan’s westernmost island, it is also the last place in the country where the sun sets. "The Hill Where Japan’s Last Sunset Can Be Seen," located north of Kubura Port, is a breathtaking romantic spot to enjoy the sunset. Although the true westernmost point is Irizaki, across the port, this hill provides the best view of the cape, lighthouse, and sunset together.

During the shorter days from autumn to early spring, the sun sets right next to Irizaki, creating an even more stunning sight. Even outside of sunset hours, the view of the cape and the vast horizon is picturesque. However, since there are no streetlights along the way, be cautious not to lose track of time and get caught in complete darkness on your way back.

2. Higashi-Zaki (Eastern Cape)

At the easternmost tip of the long, narrow Yonaguni Island lies Higashi-Zaki (Agari-Zaki). This narrow cape, surrounded by cliffs on three sides, features a small lighthouse and an observation deck. The area is dominated by the vast blue ocean and sky, and on clear days, you can see as far as Iriomote Island.

The surrounding grasslands are home to native Yonaguni horses and cattle, which freely graze. Watching these animals peacefully feed creates a calming experience. As expected, this is the first place on the island to witness the sunrise, and the morning view is just as spectacular as the sunset on the western side.

3. Underwater Ruins

In 1986, a diver discovered a massive monolithic rock off the southern coast of the island. The rock featured right-angled steps and pillar-like holes, appearing to be artificially processed, leading to speculation that it might be an ancient ruin. To this day, it remains a mystery whether it is man-made or a natural geological formation.

Since its discovery, the underwater ruins have become a popular attraction for divers visiting Yonaguni. Regardless of whether it is artificial or natural, its complex structure continues to captivate the adventurous spirit of diving enthusiasts. For experienced divers, this is a dream diving destination.

4. Semi-Submersible Underwater Ruins Tour Boat: Jack’s Dolphin

If you're interested in Yonaguni's sea and underwater ruins but don't want to go diving, the semi-submersible tour boat "Jack’s Dolphin" is a great option! This sightseeing boat has windows in its lower section, allowing passengers to sit comfortably while enjoying the stunning underwater scenery of Yonaguni.

Operated by the diving shop "Surface Yonaguni," which is attached to a hotel in the Sonai district on Yonaguni's north coast, the boat takes just 18 minutes to reach the underwater ruins. The total tour lasts about an hour. Even on days when waves make it impossible to reach the ruins, passengers can still enjoy colorful fish and coral at calmer locations.

However, since the space inside is somewhat confined and underwater, those prone to seasickness should take precautions.

5. Shikinajima Clinic

Yonaguni Island has three main settlements located in the north, west, and south. In the quiet Hikawa district on the southern coast, you'll find Shikinajima Clinic, a well-known tourist spot. The name might not immediately ring a bell, but fans of the TV drama "Dr. Koto’s Clinic" will recognize it as the filming location of the series.
The open set used in the drama was left intact after filming, turning it into a popular tourist attraction. Visitors can enter the clinic (for a fee) and even climb to the rooftop using a ladder at the back. From the top, you get a spectacular view of Hikawa Beach and its sandy shoreline. The flag of Dr. Koto still remains, allowing fans to relive scenes from the show.

6. Tachigami Rock

Tachigami Rock is a towering 30-meter-high rock formation standing along the southeastern coast of Yonaguni Island. According to legend, a young man once climbed the rock to collect seabird eggs but became trapped at the top. He prayed to the gods before falling asleep, and when he awoke, he miraculously found himself safely back on the ground. Due to this divine connection, the rock has been revered as "The Rock of the Gods."

There are two observation decks on the east and west sides of the rock, offering different perspectives for visitors to compare. Nearby, you’ll also find other interesting rock formations, including "Battleship Rock" and "Human Face Rock." Taking a leisurely drive or bike ride around the area provides plenty of scenic views.

7. Yonaguni Horse Interaction Park

The Yonaguni horse is one of the eight native horse breeds of Japan. Smaller and cuter than typical horses, they were once essential for farming, transportation, and carrying goods on the island. Due to modernization, their numbers declined significantly, but today, around a hundred of them still live on Yonaguni Island.

The Yonaguni Horse Interaction Park was established to preserve this unique breed. Visitors of all ages, including children, elderly individuals, and people with disabilities, can interact with these horses while learning about their ecology and the importance of life. The park offers three types of horseback riding experiences, ranging from beginner-friendly rides and trekking courses to advanced riding sessions by the sea and mountains.

With their friendly faces and affectionate nature, these horses are easy to bond with. Since you’ve traveled all the way to Japan’s westernmost island, don’t miss the opportunity to meet this rare native horse breed!

8. Tindahana Cliff

Behind the Sonai settlement stands a massive rock mountain, known as Tindahana Cliff, also called Tindabana. This 70-meter-high limestone cliff, formed by coral uplift, is designated as a national scenic spot.

At the top, accessible by steep slopes and stone steps, there is a natural observation deck inside an eroded cave. From here, visitors can enjoy panoramic views of Sonai Town and the sparkling emerald-green sea, surrounded by towering rock walls and dramatic scenery.

According to legend, Sannai Isoba, a female ruler from the late 15th century, once lived here. Known for her great strength and enormous stature, she ruled Yonaguni with the help of her four brothers stationed across the island. A monument dedicated to Sannai Isoba stands near the cliff.

9. Monument of Japan’s Westernmost Point

At Irizaki Cape, west of Kubura Port, stands the official westernmost point of Japan. Here, you’ll find a lighthouse, an observation deck, and a stone monument marking this significant location. During sunset, the sun sinks straight into the horizon, offering a breathtaking view, while the daytime scenery is equally spectacular.

On rare occasions, under specific conditions on just a few days each year, visitors may even catch a glimpse of Taiwan’s distant skyline. Whatever you do here, you’ll be experiencing it at Japan’s westernmost point! Unlike the country’s northern, eastern, and southernmost edges, which are difficult or impossible to access, this spot is a must-visit for travelers.

10. Kuburabari

Just north of "The Hill Where Japan’s Last Sunset Can Be Seen," there is a deep rock crevice called Kuburabari. This site is tied to a tragic legend from Yonaguni’s history. During the Ryukyu Kingdom era, Yonaguni Island suffered from food shortages due to overpopulation. As a harsh population control measure, pregnant women were forced to jump across the crevice—only those who succeeded were allowed to give birth.

Today, Kuburabari is a scenic spot offering beautiful ocean views, but it also serves as a reminder of the island’s past.

A short walk towards the sea from Kuburabari leads to Kuburafurishi, a natural rock formation resembling a stone terrace known as "Senjojiki". This is also one of Yonaguni’s iconic landscapes. There is a parking area near Kuburabari, making it convenient to visit by car or bicycle.

11. Yonaguni Town Traditional Craft Center

One of Yonaguni Island’s traditional crafts is Yonaguni Ori (Yonaguni Weaving), a textile with over 500 years of history. Once considered a tribute to the Ryukyu royal court, this ancient fabric is known for its intricate geometric designs and vibrant colors. There are four main types:

・"Hanaori" – Delicate floral-patterned weaving
・"Dutati" – Worn during festivals and ceremonies
・"Shidadi (tenugui)" – Handwoven with colored threads
・"Kagannubu" – Features elegant kasuri (splashed-pattern weaving)

Yonaguni weaving almost disappeared after World War II, but in 1979, the Yonaguni Town Traditional Craft Center was established, bringing back the sound of weaving looms. Visitors can explore the center, observe artisans at work, and even purchase woven souvenirs such as pouches and straps.

12. Sakimoto Sake Brewery

Okinawa is famous for awamori (rice liquor), but Yonaguni Island has its own unique liquor called "Hanasake" (Flower Sake). Unlike regular awamori, which has a maximum alcohol content of 45%, Hanasake contains an astonishing 60% alcohol. Because of this, Japanese law classifies it as a spirit rather than shochu.

Yonaguni has three breweries that produce Hanasake, and Sakimoto Sake Brewery is one of them. It is said to be the oldest brewery on the island, using traditional direct-fire distillation methods. The entire brewing process is done by a small group of artisans, maintaining its authentic craftsmanship.

Visitors can book a tour of the brewery to learn more about the process and try this powerful island drink.

13. Ayamihabiru Hall

The Ayamihabiru is the local name for the Yonaguni Silk Moth (Yonagunisan), one of the largest moths in the world. With a wingspan as large as a human hand, this giant moth has a unique life cycle—its adult form lacks a mouth, meaning it cannot eat and survives for only one week after emerging.

At Ayamihabiru Hall, visitors can learn about the Yonaguni Silk Moth, its connection to the island's ecosystem, and other native wildlife. A highlight of the exhibit is the mounted specimens of adult moths, showcasing their enormous size. This is a great place to experience Yonaguni’s rich subtropical nature.

14. Datiguchidi

In the pastureland extending from Higashi-Zaki, there is a historical site surrounded by low stone walls. This is Datiguchidi (Yateku Peak), one of many "Hibanmui" watchtowers built across Okinawa’s islands. During the Ryukyu Kingdom era, these watchtowers were used to monitor passing ships and signal warnings using smoke in case of emergencies. Since 2007, 19 Hibanmui sites, including Datiguchidi, have been designated as National Historic Sites under the Sakishima Islands Watchtower Network.

Datiguchidi is small in scale and may not seem particularly impressive at first glance. However, it remains a valuable historic site, carefully preserved to share Yonaguni’s rich history. Every year, on the Bing Day of the 8th month in the lunar calendar, a traditional ceremony is held, honoring the ancient watchmen who once lit fires here every night.
