Hateruma (波照間島; Hateruma-jima; Yaeyama: Patirooma, Hateruma dialect: Besїma "our island", Okinawan: Hatiruma) is an island in the Yaeyama District of Okinawa Prefecture, Japan.[1] Part of the town Taketomi, it is the southern-most inhabited island in Japan at 24°2’25" north latitude, 123°47’16" east longitude. Hateruma is one of the Yaeyama Islands, and is located 24 kilometres (15 mi) south of Iriomote-jima, the largest of the island group.[2]

Hateruma, which is composed of corals, has 12.7 km² of area and approximately 600 inhabitants.

The primary products of the island include sugarcane, pineapple, refined sugar, and Awanami, a highly prized type of the alcoholic beverage awamori.[1] Its southern location makes it one of the few places in Japan where the Southern Cross can be observed.

Hateruma is visited by a comparatively high number of Japanese tourists from Ishigaki on day trips, as it boasts the southernmost tip of land of Japan. In addition, the southernmost school and the southernmost police station of Japan are tourist attractions. Further places of interest include:

  • In the only village several well-preserved old houses showing the traditional architecture with a hip roof, red tiles and a shisa statue on the top can be seen. Many old houses are still surrounded by a thick wall consisting of dark coral stones.
  • In the village center there is a memorial to Oyake Akahachi, a rebel who was born on Haterumajima around 1500. The memorial was erected on a platform of coral stones.
  • One of the most interesting buildings on Haterumajima is the old watchtower Kodomori dating from the 17th century. It was used for observing the ships sailing to and from Ishigaki. As the top of the tower was one of the highest points of the flat island, it was used for smoke signals and for signal lights. A similar tower, which is called Puzumari, can be visited on the neighboring island Kuroshima.
  • On the south coast there is a memorial indicating the southernmost tip of land of Japan. The south coast is steep and the sea is very rough there.
  • The north coast of Haterumajima is a favorite tourist destination because of its fine sand.


Hateruma has a tropical climate as all twelve months there have mean temperatures of at least 18 °C (64 °F).


Hateruma Airport is located on the island but is not currently served by any commercial flights. Haterujima is easily accessible by ferry from Ishigaki several times a day. There are several guest houses and some shops and restaurants on the island. Bikes are for hire at the harbour.

2010 Senkaku boat collision incident

The 2010 Senkaku boat collision incident (or the Minjinyu 5179 incident) occurred on the morning of September 7, 2010, when a Chinese trawler, Minjinyu 5179, operating in disputed waters collided with Japanese Coast Guard's patrol boats near the Senkaku Islands. There were several Japanese Coast Guard (often abbreviated JCG) boats involved, including Yonakuni and Mizuki, which collided with Minjinyu 5179, plus Hateruma and other JCG boats.

The collision and Japan's subsequent detention of the skipper (Zhan Qixiong (Chinese: 詹其雄)) resulted in a major diplomatic dispute between China and Japan. When China's repeated demands for the release of the skipper were refused and the detention of the skipper extended for a further ten days, the Chinese government cancelled official meetings of the ministerial level and above. Though denied by the Chinese government, it was reported that China halted exports of rare earth minerals to Japan.The detained Chinese crew members were released without charge and were allowed to return home. In China the overall event is perceived as a diplomatic victory, while in Japan the Japanese government's "weak-kneed" handling of the issue was criticized.

Angama (dance)

Angama (アンガマ) or angama odori (angama dance) is a style of dancing that is performed in many communities of Japan's Yaeyama Islands during the Bon Festival, which is known as sōrin (< shōryō (精霊)) in Yaeyama. A related performance is known as mushāma in Hateruma. In Kohama Island, the northern community performs a dance named jiruku while the southern community performs Minma buduri.

Gusuku (グスク, 城, Okinawan: gushiku) often refers to castles or fortresses in the Ryukyu Islands that feature stone walls. However, the origin and essence of gusuku remain controversial. In the archaeology of Okinawa Prefecture, the Gusuku period refers to an archaeological epoch of the Okinawa Islands that follows the shell-mound period and precedes the Sanzan period, when most gusuku are thought to have been built. Many gusuku and related cultural remains on Okinawa Island have been listed by UNESCO as World Heritage Sites under the title Gusuku Sites and Related Properties of the Kingdom of Ryukyu.

Hateruma-class patrol vessel

Hateruma-class patrol vessel (Japanese: はてるま型巡視船) is a class of PL type patrol vessels of the Japan Coast Guard. PL stands for "Patrol vessel Large", and the class name "Hateruma" is named after Hateruma-jima, the southernmost inhabited island of Japan.

Aiming at policing of Senkaku Islands, they can be a floating base for smaller patrol crafts or helicopters, so they are called "拠点機能強化型巡視船", Patrol vessel, Sea-basing capability enhanced. The lead ship of the class, Hateruma (PL61), was one of the JCG's vessels involved in the 2010 Senkaku boat collision incident, including Yonakuni (PL63) and Mizuki (PS class), both of which collided with the Chinese fishing trawler Minjinyu 5179 which was then boarded and seized.

Ships of this class are equipped with one single-mounted Mk44 Bushmaster II 30mm autocannon with laser-optical fire-control system. The 30 mm caliber autocannon is an entirely new caliber for the JCG, and it gives this class increased firepower compared with usual 1,000 ton-class patrol vessels which normally have only one manually controlled 20 mm Vulcan Gatling gun. This 30 mm gun system is more powerful than a 20 mm Vulcan with a Remote Firing System (RFS) associated with the simplified laser-optical fire-control system (FCS) which is on board recent PMs and PSs such as the Tsurugi class, and more reasonable than the larger Bofors 40 mm L/70 gun with laser-optical FCS which is mounted on board "High-speed, High-functionality" PLs such as the Hida and Aso classes.

This class has the helicopter deck wide enough to operate with Eurocopter EC225 helicopters to airlift supplies for small patrol crafts keeping Senkaku Islands under surveillance. And the broadband SATCOM system of this class can relay video data from helicopters to the ground station or the HQ of the JCG. This class is equipped with the LIDAR system to acquire targets with high accuracy, and at the same time, this system enables them to perform search and rescue mission more safely.

The JCG had intended to build a number of ships of this design for the successor of PL-101 Shiretoko-class, but this class may not suitable for SAR mission because of the insufficient low-speed mobility. So the construction project has switched to the PL-09 Kunigami-class, utilized variant of this class.

The Shiretoko class is the older 1,000 ton-class PLs, twenty-eight ships were built in late 1970s and early 1980s. It was announced that Japan plans to transfer two of the older Shiretoko-class type patrol vessels to the Philippines Coast Guard in 2012.

Naata Ufushu

Naata Ufushu (長田大主, 1456-1517) was a Ryukyuan local chief who supported the forces of the Ryūkyū Kingdom in suppressing the rebellion of Oyake Akahachi, another regional chieftain.

Naata was born on Hateruma Island and traveled to Ishigaki Island at the age of eight. Over the years, as he grew, he gained power, eventually uniting Ishigaki Village and becoming its head.He was approached, as were a number of other local chieftains, by Oyake Akahachi, who sought to have them join him in rebellion against the Ryūkyū Kingdom. Naata is said to have been quite loyal to the king, and sought to appease Akahachi by offering him his younger sister Koitsuba's hand in marriage; this failed, and Akahachi escaped to Iriomote Island with Koitsuba and her two younger brothers.Akahachi was defeated in the end by royal forces, with Naata's support.It is sometimes said that Naata was the son of Nakasone Toyomiya, or otherwise descended from him, but this seems unlikely, as Nakasone is known to have lived sometime around 1500-1530, which would make him younger or contemporaneous with Naata, not old enough to be his father or other ancestor.

Oyake Akahachi

Oyake Akahachi (遠弥計赤蜂) was a Ryukyuan lord (aji) of Ishigaki Island who led a rebellion against the Ryukyu Kingdom in 1500.

Ryukyu Air Commuter

Ryukyu Air Commuter Co., Ltd. (琉球エアーコミューター株式会社, Ryūkyū Eā Komyūtā Kabushiki-gaisha) is an airline headquartered in Naha, Okinawa Prefecture, Japan. It operates domestic passenger services from the island of Okinawa to other islands of Okinawa Prefecture and the Amami Islands, Kagoshima Prefecture.

Sakishima Beacons

The Sakishima Beacons (先島諸島火番盛, Sakishima-shotō hibanmui) are a network of eighteen observation platforms and beacons dating to the early Edo period and located in the Sakishima Islands, Okinawa Prefecture, Japan. Erected in 1644 by the government of the Ryūkyū Kingdom at the instigation of the Satsuma overlords, at a time of international tension during the transition between the Ming and the Qing Dynasties of China, the beacons were responsible for monitoring and reporting on maritime traffic, with a view to restricting foreign vessels in accordance with the Tokugawa policy of sakoku, i.e. national seclusion. After an initial survey by the Council for the Protection of Cultural Properties in 1993, due to uncertainties over land rights and difficulties of coordination between the involved municipalities, it was not until 2007 that they were jointly designated an Historic Site.

Taketomi, Okinawa

Taketomi (竹富町, Taketomi-chō, Yaeyama: Teedun, Okinawan: Dakidun) is a town located in Yaeyama District, Okinawa Prefecture, Japan.

The town includes all of the islands in the Yaeyama Islands excluding Ishigaki, Yonaguni, and the Senkaku Islands. This includes the islands of Iriomote, Taketomi, Kohama, Kuroshima, Hateruma, and Hatoma. Although Ishigaki is not part of the town of Taketomi, the town hall is located there.

As of October 2016, the town has an estimated population of 4,050 and the density of 12 persons per km2 (31/sq mi). The total area is 334.02 km2 (128.97 sq mi).

Yaeyama District, Okinawa

Yaeyama (八重山郡, Yaeyama-gun, Yaeyama: Yaima, Yonaguni: Daama, Okinawan: Yeema) is a district located in Okinawa Prefecture, Japan. The district covers all of the Yaeyama Islands except Ishigaki and the disputed Senkaku Islands.

As of 2003, the district has an estimated population of 5,579 and the density of 15.37 persons per km². The total area is 362.89 square kilometers.

Yaeyama Islands

The Yaeyama Islands (八重山列島 Yaeyama-rettō, also 八重山諸島 Yaeyama-shotō, Yaeyama: Yaima, Yonaguni: Daama, Okinawan: Yeema) are an archipelago in the southwest of Okinawa Prefecture, Japan, and cover 591.46 square kilometres (228.36 sq mi). The islands are located southwest of the Miyako Islands, part of the Ryukyu Islands archipelago. The Yaeyama Islands are the remotest part of Japan from the main islands and contain Japan's most southern (Hateruma) and most western (Yonaguni) inhabited islands. The city of Ishigaki serves as the political, cultural, and economic center of the Yaeyama Islands.The Yaeyama Islands are home to numerous species of subtropical and tropical plants, and mangrove forests. The islands produce sugarcane and pineapples. Coral reefs around the islands are ideal habitats for dolphins, sea turtles, and larger fish such as manta rays and whale sharks. Before being wiped out by humans, whales and dugongs were common as well, and Yaeyama once had the largest population of dugongs in the Ryukyu Islands. On Aragusuku Island, there is a Utaki which specially enshrines hunted dugongs with their skulls, but non-residents are not permitted to enter unless they receive special permission from inhabitants, and it is said that any aliens without permission will be driven out by force.

Yaeyama Subprefecture

Yaeyama Subprefecture (八重山支庁, Yaeyama-shichō) was a subprefecture of Okinawa Prefecture, Japan. It was abolished in March 2009. Most of its functions were taken over by the Yaeyama Office of the prefecture.

It included the following cities and towns of Yaeyama and Senkaku Islands:

Ishigaki (city on Ishigaki and Senkaku Islands)

Taketomi (town on Iriomote, Taketomi, Kohama, Kuroshima, Hateruma, Hatoma, and others)

Yonaguni (town on Yonaguni)

Yaeyama language

The Yaeyama language (八重山物言/ヤイマムニ, Yaimamuni) is a Southern Ryukyuan language spoken in the Yaeyama Islands, the southernmost inhabited island group in Japan, with a combined population of about 53,000. The Yaeyama Islands are situated in the Southern Ryukyu Islands, southwest of the Miyako Islands and to the east of Taiwan. Yaeyama (Yaimamunii) is most closely related to Miyako. The number of competent native speakers is not known; as a consequence of Japanese language policy which refers to the language as the Yaeyama dialect (八重山方言, Yaeyama hōgen), reflected in the education system, people below the age of 60 tend to not use the language except in songs and rituals, and the younger generation exclusively uses Japanese as their first language. As compared to the Japanese kokugo, or Japanese national language, other Ryukyuan languages such as Okinawan and Amami have also been referred to as dialects of Japanese. Yaeyama is noted as having a comparatively lower "language vitality" among neighboring Ryukyuan languages.Yaeyama is spoken in Ishigaki, Taketomi, Kohama, Kuroshima, Hatoma, Aragusuku, Iriomote and Hateruma, with complications of mutual intelligibility between dialects as a result of the Yaeyama Islands' large geographic span. The speech of Yonaguni Island, while related, is usually considered a separate language. The Taketomi dialect may instead be a Northern Ryukyuan language common to Okinawan dialects that later converged with the other Yaeyama dialects..
