Tokunoshima Island: A Natural Haven in the Amami Archipelago
Located in the East China Sea, Tokunoshima (also known as Tokuno Island) is a captivating volcanic gem within the Amami archipelago of Kagoshima Prefecture, Japan. As the 15th largest island in the country, it serves as a bridge between the Satsunan and Ryukyu archipelagos, offering a unique blend of rugged geography, rare biodiversity, and a culture that harmonizes Japanese and Ryukyuan influences.
Beyond its scenic beauty, Tokunoshima is distinguished by remarkable demographic trends, boasting the highest fertility rate in Japan (2.25 between 2018 and 2022) and a notable population of supercentenarians—individuals who have lived beyond the age of 110.

Geography and Climate
Tokunoshima measures approximately 25 kilometers in length and 18 kilometers in width. The landscape is diverse, characterized by the mountainous terrain of Tokunoshima and Amagi towns, and the flatter, fertile agricultural lands of Isen. The island's highest peak, Mount Inokawadake, reaches 645 meters, while the northern region is dominated by Mount Amagidake.
The coastline is rugged and rocky, featuring steep cliffs and small sandy beaches, all encircled by a protective coral reef. Offshore, the Tonbura Rocks stand as a prominent geological feature. The island's interior is a subtropical moist broadleaf forest ecoregion, containing rainforests and laurel forests, as well as extensive cave systems—the longest of which in Isen reaches 2,052 meters.
The climate is classified as humid subtropical (Köppen Cfa), featuring mild winters and very warm summers. A rainy season persists from May through September, and the island is frequently impacted by typhoons.
Rare Fauna and Biodiversity
Due to its isolation, Tokunoshima is a sanctuary for several endemic species. Most notable is the Amami rabbit, an endangered "living fossil" representing an ancient Asian lineage found only here and on Amami Ōshima. The island also hosts the endangered Tokunoshima spiny rat and the Lidth's jay.
The forests are also home to the venomous habu snake. Interestingly, the presence of this snake has historically deterred human intrusion, helping to keep the island's most rugged forest areas relatively untouched.
History and Cultural Heritage
Tokunoshima's history is marked by its strategic position. It is mentioned in the 8th-century Nihon Shoki and was a primary center for Kamui ware (grey stoneware) production starting in the 11th century. Originally part of the Ryukyu Kingdom, the island was invaded by the Satsuma Domain in 1609 and officially incorporated into their holdings by 1624.
Satsuma rule was notoriously harsh, forcing inhabitants into serfdom to produce sugar cane for high taxes, which led to severe famines, including one in 1755 that claimed 3,000 lives. The island also served as a place of exile for the famous samurai Saigō Takamori in 1862.
Culturally, the island is a melting pot. The local cuisine blends Japanese and Okinawan dishes, such as goya chanpurū, and the sanshin (a three-stringed instrument) is widely played. While the indigenous Ryukyuan language, known locally as shimaguchi, has largely been replaced by Japanese, specific phrases like oboradaren (thank you) remain in use.
The heart of local social life is tōgyū, a form of bullfighting where bulls with locked horns push each other out of a ring. This tradition is so central to the island's identity that the tōgyū bull serves as the official mascot.
Economy and Infrastructure
Agriculture is the backbone of the economy, with sugar cane being the primary crop. This is processed into brown sugar and brown sugar shōchū (a distilled spirit). Other crops include sweet potatoes, rice, ginger, and tropical fruits like mangoes and papayas. Commercial fishing and tourism also contribute significantly to the local economy.
Transportation is managed via the port of Kametoku and the smaller port of Hetono, providing ferry links to Amami, Okinoerabu, Kagoshima, and Kobe. Air travel is available through Tokunoshima Airport in Amagi. The island's road network is anchored by Kagoshima Prefecture Highway 80, which connects the major hubs of Amagi, Kametsu, and Isen.
Notable Landmarks
- Mushiroze: A coastal area featuring granite slabs shaped by erosion to look like mushiro (woven straw mats).
- Cape Inutabu: The westernmost point of the island, offering panoramic views and a memorial to the battleship Yamato, which sank nearby during World War II.
- Amami Guntō National Park: A vast protected area established in 2017 that encompasses much of the island's natural beauty.

Frequently Asked Questions
What is the Amami rabbit and why is it special?
The Amami rabbit is an endangered species found only on Tokunoshima and Amami Ōshima. It is considered a "living fossil" because it represents an ancient Asian rabbit lineage that has gone extinct everywhere else in the world.
What is Tōgyū?
Tōgyū is a traditional Japanese style of bullfighting practiced on the island. Unlike Spanish bullfighting, it involves two bulls with locked horns pushing each other out of a ring, guided by human coaches.
Why is Tokunoshima known for its birth rate?
Tokunoshima has gained attention for having the highest fertility rate in Japan, recorded at 2.25 between 2018 and 2022, which is significantly higher than the national average.
What is Kamui ware?
Kamui ware is a type of grey stoneware produced on Tokunoshima starting in the 11th century. It was widely traded across the Ryukyu Islands and southern Kyūshū, and its production sites are now designated as national historic sites.
How do I get to Tokunoshima?
Visitors can arrive via Tokunoshima Airport in Amagi or by ferry through the ports of Kametoku and Hetono, with regular services connecting the island to Kagoshima, Amami, and Okinoerabu.
