Explore the Northernmost Remote Island of Okinawa! 10 Must-Visit Attractions in Iheya Island

Located about a two-hour ferry ride from Unten Port in northern Okinawa, Iheya Island is the northernmost inhabited island in Okinawa Prefecture. This hidden paradise is characterized by a series of small mountains reaching around 200 meters in height, forming a long and narrow island shape. Known as one of Okinawa’s lesser-known diving spots, Iheya Island offers pristine blue skies, crystal-clear waters, and untouched nature, making it a serene getaway far from crowded tourist areas.

Since there is no airport on the island, the number of visitors remains relatively low, allowing for a peaceful retreat surrounded by breathtaking landscapes. The island is home to traditional Ryukyuan-style houses, offering a glimpse into Okinawa’s rich cultural heritage. Here, you won’t find noisy city life—only tranquil coastal views and an authentic island experience.

If you’re planning a trip to Iheya Island, don’t miss these 10 must-visit tourist attractions that showcase the island’s natural beauty and cultural significance!

1. Tana no Kuba-yama

At the northernmost tip of Okinawa's remote Iheya Island, you'll find Tana no Kuba-yama (久葉山), a breathtaking natural wonder officially designated as a Prefectural Natural Monument in 1958. This lush, green paradise is home to Kuba trees (Livistona chinensis), a species of evergreen fan palm that grows densely across the mountain. While many associate Okinawa with sugarcane or coconut palms, Kuba trees have played a vital role in local life for centuries. Their dried leaves were traditionally used for roofing, boat sails, and even as handmade fans.

The sight of these towering fan palms covering the mountain from the shoreline to the peak is nothing short of spectacular. Beyond its natural beauty, Kuba trees are considered sacred, believed to house divine spirits. This makes Kuba-yama a mystical sanctuary—a place where gods are said to rest their wings. At the summit, a white lighthouse stands in contrast to the deep green landscape, adding a stunning visual accent to the scenery. For travelers seeking an untouched Okinawan wilderness, this is the perfect destination.

2. Torazu Iwa

Before setting foot on Iheya Island, travelers arriving by ferry from Unten Port on the Motobu Peninsula will first encounter the majestic Torazu Iwa (虎頭岩)—the “Tiger Head Rock.” Towering behind Maedomari Port, this colossal rock formation, sculpted over time by wind and waves, resembles a crouching tiger watching over the island. Many locals believe this sacred rock embodies a divine guardian, protecting those who come and go.

A stairway leads up the rock, offering a panoramic view of Iheya Island from its summit. The island is famous for its crystal-clear coral seas and untouched greenery, and the best way to admire these natural wonders is from the back of the tiger itself. After enjoying the breathtaking scenery, visitors can descend the stairs and explore the forest park at the base of the rock—perfect for hiking and leisurely walks.

3. Kumaya Cave

One of the most fascinating attractions on Iheya Island is Kumaya Cave. This natural formation was created over 280 million years ago, as wind, waves, and rain gradually eroded the rocks to form this breathtaking cave. With an entrance standing 5 meters high and an interior spanning 600 tsubo (approximately 2,000 square meters), visitors must pass through a narrow rock passage to reach the main cavern. The thrill of the journey and the sense of openness upon arrival make it an unforgettable experience. The cave remains dark at all times, exuding a mysterious and mystical ambiance. Even in the scorching summer, the cave stays refreshingly cool, allowing visitors to spend hours exploring comfortably.

However, Kumaya Cave is more than just a natural wonder. The name "Kumaya" means "to hide," and the cave holds deep historical and mythological significance. The Edo-period scholar Sadataka Fujii proposed that this could be the actual location of the "Amano Iwato" (Heavenly Rock Cave) from Japanese mythology, where Amaterasu, the Sun Goddess, once hid. This theory sparked a major debate with the renowned scholar Motoori Norinaga, and to this day, researchers from across Japan visit the site for further study. A remote island in Okinawa connected to the creation myths of Japan—Kumaya Cave is a place where history, nature, and legend intertwine, making it an extraordinary destination for travelers.

4. Nentou Hiramatsu

Nentou Hiramatsu (Nentō Hiramatsu) is a legendary pine tree that stands alongside Kume Island's "Goeda no Matsu" as one of Okinawa’s two most famous pines. This massive tree belongs to the Ryukyu pine species, which typically grows vertically. However, Nentou Hiramatsu has expanded horizontally like a giant umbrella, creating a stunning natural spectacle. Estimated to be between 200 to 300 years old, the tree stands 8 meters tall with an incredible 25-meter-wide canopy. In 2016, it was designated as a National Natural Monument, further solidifying its cultural and ecological importance.

Recognized as one of Japan’s "100 Remarkable Trees," Nentou Hiramatsu is surrounded by a well-maintained park, making it an excellent stop for nature lovers. According to legend, the tree we see today is actually the second generation of Nentou Hiramatsu. Long ago, there was a magnificent pine tree called "Aniki Matsu" (Brother Pine) in the same location. However, a man named Santachiku from Izena Island cut it down, and as a result, he fell ill and died, believed to be cursed by the tree's spirit. His younger brother and relatives planted a new pine in atonement, which grew into the grand Nentou Hiramatsu we see today.

As a symbol of Iheya Island’s natural heritage, this majestic pine is a must-visit landmark for those exploring the region.

5. Yagura Tomb

Nestled along the rugged southwestern coastline of Iheya Island, the Yagura Tomb (屋蔵墓) is a fascinating historical site with mysterious origins. Though its construction remains unclear, the tomb houses a stone monument dedicated to Yagura Ufunushi (屋蔵大主), the founding ancestor of the First Shō Dynasty of the Ryukyu Kingdom. Adjacent to the incense burner inscribed with "First Shō Dynasty" stands the black granite mausoleum of Yagura Ufunushi.

According to legend, Yagura Ufunushi lived around 600 years ago in the Uezato area of Wakiyashiku, a village located about 1 km from the tomb. In 1935, his descendants visited the site and conducted a survey, uncovering six stone funerary urns. Among them, one was made of Nanban-yaki, a type of ceramic ware, suggesting that it contained the remains of Yagura Ufunushi himself.

This natural cave-turned-burial site offers a glimpse into Okinawa’s ancient history and the legacy of the Ryukyu Kingdom. If you’re exploring Iheya Island, Okinawa’s northernmost island, don’t miss the opportunity to step into this historical landmark and connect with the region’s rich past.

6. Noho Island

With a population of only around 100 people, Noho Island (野甫島) is a tranquil, remote island connected to Iheya Island via the stunning 600-meter Noho Bridge. From the bridge, visitors can enjoy breathtaking views of crystal-clear waters and coral reefs, while the island’s pristine white sandy beaches provide the perfect setting for relaxation.

Despite its modest elevation of only 40 meters, Noho Island’s flat landscapes, surrounded by open fields and sandy shores, create a secluded, tropical escape. It feels like a hidden paradise, where you can experience the simple beauty of nature and slow down from the busy world.

The island is home to sprawling sugarcane and sweet potato farms, adding to its peaceful, rural charm. There is only one small cooperative store, operated by the locals, which has become a beloved stop for visitors looking for a taste of the island’s simple lifestyle.

Noho Island’s sea salt has become a popular souvenir. One of the finest products is Shiomu Sumi, a 100% natural salt extracted from seawater using a unique process. The seawater is sprayed over Japanese cypress wood, compressed with wind power, and carefully hand-processed to preserve its rich minerals. This chemical-free “Salt of Happiness” is not only a healthy seasoning but also a meaningful gift from the island. The residual liquid from the salt-making process is also used to create "Umi no Sachi" (Blessings of the Sea), a mineral-rich nigari extract that enhances the flavor of drinking water.

If you’re looking for a peaceful getaway off the beaten path, Noho Island offers an authentic, unspoiled island experience that’s perfect for nature lovers and adventure seekers alike.

These structures are characterized by their short pillars and thatched roofs and are still used today for traditional festivals and rituals. The surrounding area, known as "Ashibina" (遊び庭), serves as an open space where Kami Ashibi (sacred dance performances) take place in dedication to the gods.
