Tachikiri Ruins and Yokomine Ruins

The Yokomine Site, discovered in 1992

The Yokomine Site in Minamitane Town was the first Paleolithic site ever found on Tanegashima. Excavations begun in 1992 revealed three superimposed Paleolithic occupation layers. Beneath the layer of volcanic ash known as the Tane IV (Tane-yon) tephra — laid down approximately 30,000 to 35,000 years ago — researchers uncovered nine clusters of fire-cracked stones. These pebble groupings are believed to be cooking installations, and they were recognised as among the oldest cooking facilities ever identified in Japan. Pounders, anvil stones, grinding stones, and pebble tools were also recovered. The site received prefectural historic site designation on April 28, 2003.

The Tachikiri Site, discovered in 1995

Three years later, in 1995, the Tachikiri Site came to light in Nakatane Town. Full-scale excavation in 1997 by the Nakatane Town Board of Education stunned the archaeological community: beneath the same Tane IV ash layer, investigators found pit features, hearth traces (14 of them), stone clusters that suggested cooking activity, and a striking variety of stone tools — grinding stones, pounders, anvils, whetstones, pebble tools, chipped stone axes, and partially polished stone axes. At the time, it was hailed as the oldest evidence of settled domestic life in Japan.

Later excavations from 2006 to 2007, prompted by improvements to National Route 58, uncovered something even more extraordinary at the Otsuhohata district within the Tachikiri Site: twelve apparent pit traps. Continued work from 2008 onward by the local board of education confirmed the interpretation, and the cumulative count rose to 24 trap features. The site was designated as a Kagoshima Prefecture historic site in 2015.

Joint national designation in 2022

Because the two sites share the same dating, the same volcanic-ash horizon, and the same cultural character, the national Council for Cultural Affairs recommended that they be designated jointly. On November 10, 2022, "Tachikiri Site and Yokomine Site" became one of Japan's officially registered national historic sites — a recognition reserved for places of outstanding significance to the country's history.

Japan's oldest known pit traps

The 24 funnel-shaped pits at Tachikiri are widely regarded as the oldest hunting pit traps yet found in Japan. Unlike the deeper, narrower traps found at sites such as those in Shizuoka Prefecture, the Tachikiri features open in a flared, trumpet-like profile. Researchers had to carefully rule out other interpretations, but the way the pits follow the contour of a shallow former valley — a natural game trail — together with the absence of cooking debris in their immediate surroundings, persuaded specialists that these were indeed traps for capturing animals.

The oldest stone-steaming cooking installations in Japan

The clusters of fire-cracked pebbles at both sites are interpreted as the remains of "stone-steaming" or stone-boiling cookery, in which heated stones were used to cook food. Recognised as among Japan's oldest cooking installations, these features show that the people of Tanegashima were already preparing meals in sophisticated ways more than thirty thousand years ago.

A revolution in our view of Paleolithic life

Older textbooks portrayed Japan's Paleolithic people primarily as nomadic big-game hunters who followed prey across the landscape. The plant-processing tools at Tachikiri and Yokomine — grinding stones, anvils, and pebble tools — combined with the stone axes used for felling trees and working wood, point instead to a settled or semi-settled way of life that depended heavily on plant foods. Pollen analysis confirms that the surrounding landscape was already an evergreen broadleaf laurel forest, much like the one that covers parts of southern Kyushu today. The inhabitants had clearly adapted their lifeways to that warm, wooded environment.

Evidence of seafaring

Some of the partially polished stone axes recovered from Tachikiri are made from rock that originates on the neighbouring island of Yakushima. Because Tanegashima was already separated from the mainland by sea at this period, the presence of imported stone implies that the people who lived here possessed boats capable of crossing open water. This is one of the earliest hints of seafaring in the Japanese archipelago, with profound implications for how Homo sapiens spread southward into the islands.

Standing where the world's oldest pit traps once lay

The Tachikiri Site occupies a sugarcane-covered plateau at about 112 metres above sea level in the Sakai district of Nakatane Town. Walking the surrounding farmland, with the green fields rolling toward the Pacific in one direction and the laurel-forested ridges in the other, gives a powerful sense of why prehistoric people chose this place. Subtle dips in the terrain still mark the shallow ancient valley along which the trap line was constructed.

Excavated artifacts at the Nakatane Town History and Folklore Museum

The actual stone tools and other recovered objects from the Tachikiri Site are kept and displayed at the Nakatane Town History and Folklore Museum, located along National Route 58 in the centre of the island. The museum's second floor showcases the Paleolithic artifacts in context, while the first floor offers a beautifully reconstructed early-twentieth-century farmhouse, traditional sugarcane-pressing equipment, and the last surviving dugout canoe of Tanegashima — a moving juxtaposition of life across the ages on a single small island.

Yokomine Site and the southern lookouts of Minamitane Town

The Yokomine Site lies on a similarly elevated plateau in southern Minamitane Town. The artifacts from this site are managed by the local government, and visitors travelling between Tanegashima Space Center to the south and the historic village of Nishinoomote to the north can see how the prehistoric occupants chose strategic plateaus close to fresh water and rich woodland.

Imagining the laurel forest world

Much of Tanegashima's interior is still covered by the warm, humid evergreen laurel forest characteristic of southern Japan. Walking through these woodlands today, with their glossy leaves, dense undergrowth, and birdsong, gives travellers a tactile sense of the ecosystem that sustained the people of 35,000 years ago. The contrast with the cold, mammoth-haunted steppes often associated with the Paleolithic world is striking.

Tanegashima Space Center

Located on the southeastern coast of Minamitane Town, the Tanegashima Space Center is one of the most scenic rocket-launch facilities in the world. The free-to-enter Space Science and Technology Museum offers interactive exhibits, and tours of the launch facilities are available with advance reservation. Standing at the same southern tip of the island where Paleolithic ancestors once ranged, while watching modern rockets prepare to leave Earth, is a uniquely moving experience.

Hirota Site (Minamitane Town)

For visitors interested in archaeology, the Hirota Site offers an entirely different chapter of Tanegashima's past. Dating from the late Yayoi period through the seventh century, this nationally designated historic site is famous for its remarkable shell-bead culture — a tradition unique to the island. Its excavated objects are designated as Important Cultural Properties.

Tanegashima Development Center (Teppokan)

In Nishinoomote City, this museum tells the story of how the Portuguese first introduced the matchlock musket to Japan in 1543, an event that took place on Tanegashima. Around one hundred historic firearms are displayed alongside artifacts illustrating the island's role as a southern gateway to Japan.

Tanegashima Mangrove Forest

The mangrove forests along the Kunigamiminato River and Atake River — themselves a designated national natural monument — are the northern limit of natural mangrove distribution in Asia. Kayak tours through the mangroves offer an unforgettable encounter with one of the island's most distinctive ecosystems.

Beaches and surfing

The east coast of Tanegashima is famed throughout Japan for its surfing waves, while quiet white-sand beaches on the western coast are perfect for swimming and sunset watching during the warmer months.
