Historic Sites, Places of Scenic Beauty, and Natural Monuments of Okinawa

Agena Castle Ruins crown a coral-limestone crag above the Tengan River in Uruma. Okinawa's only surviving concentric gusuku, with walls reaching ten meters.

On Goten-yama hill near Shuri Castle, this Ryukyuan princely villa garden preserves curving stonework and a complex pond. Designated 2009; closed for restoration.

Carved into Ryukyu limestone bedrock for vassals of the Ryukyu kings, this Shuri garden hides stone arch bridges and Chinese characters cut by an 1800 envoy.

A National Natural Monument on Iheya Island, Okinawa — a naturally regenerating Ubamegashi (Japanese evergreen oak) grove clinging to the cliffs of Torazu-iwa rock at the southern limit of the species' Japanese range, with rare biogeographical value as a relict population from the Asian continent.

The Ireibaru Site in Chatan Town, Okinawa, is a nationally designated historic site preserving roughly 7,000 years of continuous human life from the early Jomon period through the Gusuku era. Centered on the perpetually flowing Uchinukā spring, the waterlogged lowlands have yielded Okinawa's oldest wooden artifacts, the prefecture's first comb, jadeite from Niigata, and obsidian from Kyushu, attesting to wide-ranging exchange between the southern islands and mainland Japan. Opened to the public in 2025, the site park and the adjacent Chatan Town Museum offer a vivid hands-on encounter with prehistoric Okinawa.

Perched on the summit of Mount Uegusuku at 310 meters on the island of Kumejima, the Uegusuku Castle Ruins are the highest gusuku site in Okinawa Prefecture and a designated National Historic Site. Built during the Gusuku period (14th–15th century) by Kume Nakagusuku Aji, the fortress fell in 1510 to the forces of King Shō Shin during the unification of the Ryukyu Kingdom. Visitors today can walk among surviving stone walls of platy hornblende andesite, view the ceremonial platform and sacred garden, and learn about the Chinese ceramics and tea utensils unearthed here that attest to vibrant maritime trade. The summit offers a breathtaking 360-degree panorama of the entire island and beyond.

Perched on a clifftop near Cape Hedo at the very northern tip of Okinawa's main island, the Usahama Site is a National Historic Site that revealed the first prehistoric dwelling remains ever found in the Okinawa Islands. Excavated in 1970 by the Ryukyu Government, it produced a distinctive pointed-bottom pottery known as Uzahama-style ware, parallel to the Amami Islands' Usuku Upper Layer style and dated to the transition from late Jomon to early Yayoi. Designated on May 15, 1972—the very day Okinawa returned to Japan—it offers travelers in Yanbaru National Park a quiet vantage on three thousand years of island history.

Uchima Udun in Nishihara Town, Okinawa, is a National Historic Site and a sacred hall built in 1666 on the former residence of Kanamaru — the humble farmer who became King Sho En, founder of the Second Sho Dynasty. Its well-preserved 1736 stone walls and building foundations vividly convey the state-led veneration practices of the early modern Ryukyu Kingdom. The magnificent sawafuji tree at the entrance is also a highlight.

Discover the Ubundoru Yaeyama Palm Colony, a designated National Natural Monument hidden deep in the Iriomote Island jungle. Around 1,769 endemic palms tower above the Nakama River, forming one of only three wild populations of this Yaeyama-exclusive species on Earth.

The Enkakuji Temple Ruins in Shuri, Naha, preserve the footprint of the head temple of Rinzai Zen Buddhism in the Ryukyu Kingdom and the mortuary temple of the Second Shō Dynasty. Founded in 1494 by King Shō Shin to honor his late father King Shō En and modeled on Engaku-ji of Kamakura, the great seven-hall complex was almost entirely lost in the 1945 Battle of Okinawa. The surviving Hōjō-bashi stone bridge (a National Important Cultural Property), with its exquisite Ming-influenced relief carvings, the restored main gate, and the recently rebuilt Sanmon gate together evoke the dignity of this royal Zen sanctuary. Designated a National Historic Site on May 15, 1972, the very day Okinawa was returned to Japan, the ruins are a quietly powerful highlight of any visit to Shuri Castle.

On the northern shore of Oike, a karst lake at the heart of remote Minami-Daito Island in Okinawa, a small grove of Ohirugi mangroves grows in fresh inland water — far from the brackish estuaries where the species normally thrives. Designated a National Natural Monument of Japan in 1975, this rare "inland-locked" mangrove community is a living record of the island's geological uplift from coral reef to land. A wooden boardwalk leads visitors through this remarkable ecosystem, found nowhere else in such form.

Discover Katsuren Castle Ruins, a UNESCO World Heritage gusuku in Uruma City, Okinawa. Famed for its sweeping stone walls, panoramic Pacific views, and the legendary 15th-century lord Amawari who built a maritime trading empire.

Designated a National Historic Site in 1972, the Kabira Shell Mound on Ishigaki Island is the founding site of prehistoric research in Japan's Sakishima Islands. First surveyed by Torii Ryūzō in 1904, the two hills of Nakamamori and Shishimori yielded 14th–16th-century earred pottery and Chinese ceramics, telling a story of Yaeyama's distinctive culture and its ties to the continent.

The Kyan Coast and Arasaki Coast in Itoman City, Okinawa, was designated in 2012 as both a National Place of Scenic Beauty and a National Natural Monument. Cliffs of Ryukyu limestone rising about 30 meters above the sea, surf-bench formations carved by relentless waves, the legendary boulder known as Kasakanjā, and a remarkable zonal distribution of coastal vegetation together form a unique landscape at the southern tip of Okinawa Island. Within the Okinawa Battlefield Quasi-National Park, it offers visitors both natural grandeur and a moving sense of historical memory.

Discover Gushihara Shell Mound, a nationally designated historic site on Ie Island, Okinawa, where 5,000 years of shell artifact culture and ancient maritime trade between Okinawa and Kyushu come alive.

The Nakabaru Site preserves a 2,500-year-old Jōmon village with limestone-walled pit dwellings on Okinawa's Ikei Island. Designated a national historic site in 1986.

A 2-km limestone cape at Miyako Island's eastern tip. National Place of Scenic Beauty (2007), with coral reefs, wind-shaped plants and a climbable lighthouse.

Discover the Minamidaito Island East Coast Plant Community, a nationally designated Natural Monument in Okinawa. Home to rare Borojino spurge and coastal plants found nowhere else, this coral limestone reef landscape offers a unique botanical experience on one of Japan's most remote islands.

Japan's largest open-air travertine terraces—about 300 limestone pools formed over 3,600 years by the Tidagā spring—step down a sea cliff on Miyako Island's coast.

An 1819 Ryukyuan karesansui in Ishigaki by the Shuri master Gusukuma Peechin: five coral-limestone hills descend past a dry waterfall. Place of Scenic Beauty.
