Akusekijima is located 38 kilometres (21 nmi) southwest of Nakanoshima. The island has an area of approximately 7.49 square kilometres (2.89 sq mi) with a length of about 3.2 kilometres (2.0 mi) and a width of 2.5 kilometres (1.6 mi).Most of the island is surrounded by steep cliffs.

The island is an andesitedacite stratovolcano formed by two summit crater, Biroyama (ビロ山) 355.5 metres (1,166 ft) and Nakadake (中岳). 464 metres (1,522 ft). Mitake (御岳山) 584 metres (1,916 ft), the highest elevation on the island, is a lava dome. Lava flows in the northern portion of the island have been dated to 80,000 years ago. There has been no volcanic activity in historic times.

Its climate is classified as subtropical, with a rainy season from May through September.


Until 1624, the island was part of the Ryukyu Kingdom. During the Edo period, Takarajima was part of Satsuma Domain and was administered as part of Kawabe District. In 1896, the island was transferred to the administrative control of Ōshima District, Kagoshima, and from 1911 was part of the village of Toshima, Kagoshima. From 1946-1952, the island was administered by the United States as part of the Provisional Government of Northern Ryukyu Islands.

During World War II, on 22 August 1944, Tsushima Maru, a Japanese passenger/cargo ship, was sunk just outside Akusekijima’s northwest coast by torpedoes launched by the submarine USS Bowfin (SS-287) off this island, killing 1,484 civilians including 767 schoolchildren. Annual commemorations are held on the island and there is also a memorial museum.

Akusekijima drew attention during the Solar eclipse of July 22, 2009, which was the longest total solar eclipse of the twenty-first century, as the island was one of the closest inhabited areas to the location of maximum eclipse duration. Touted as was one of the best observation spots for the event, village officials and island residents were concerned about playing host to hundreds of people coming to view the solar eclipse. Akusekijima only has five small minshuku guesthouses, which can only accommodate up to 66 people, and water resources are limited as rainfall is the primary source of water.


Akusekijima is also famous for the masked god Boze (ボゼ), the island deity. Islanders donning Boze masks come out during the annual lunar O-Bon matsuri. Protectors of the island and its natural assets, the Boze frighten small children to ensure their safety for the coming year.

Ryukyu Islands

The Ryukyu Islands (琉球諸島, Ryūkyū-shotō), also known as the Nansei Islands (南西諸島, Nansei-shotō, lit. "Southwest Islands") or the Ryukyu Arc (琉球弧, Ryūkyū-ko), are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island.

The climate of the islands ranges from humid subtropical climate (Köppen climate classification Cfa) in the north to tropical rainforest climate (Köppen climate classification Af) in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs.

The Ōsumi and Tokara Islands, the northernmost of the islands, fall under the cultural sphere of the Kyushu region of Japan; the people are ethnically Japanese and speak a variation of the Kagoshima dialect of Japanese. The Amami, Okinawa, Miyako, and Yaeyama Islands have a native population collectively called the Ryukyuan people, named for the former Ryukyu Kingdom that ruled them. The varied Ryukyuan languages are traditionally spoken on these islands, and the major islands have their own distinct languages. In modern times, the Japanese language is the primary language of the islands, with the Okinawan Japanese dialect prevalently spoken. The outlying Daitō Islands were uninhabited until the Meiji period, when their development was started mainly by people from the Izu Islands south of Tokyo, with the people there speaking the Hachijō language.

Administratively, the islands are divided into Kagoshima Prefecture (specifically the islands administered by Kagoshima District, Kumage Subprefecture/District, and Ōshima Subprefecture/District) in the north and Okinawa Prefecture in the south, with the divide between the Amami and Okinawa Islands, with the Daitō Islands part of Okinawa Prefecture. The northern (Kagoshima) islands are collectively called the Satsunan Islands, while the southern part of the chain (Okinawa Prefecture) are called the Ryukyu Islands in Chinese.
