Daitō Islands (大東諸島 Daitō Shotō; formerly Borodino Islands) are three eastern islands of Okinawa Islands. From north to south, the islands are:

[edit] History of the European Sightings of the Daitō Islands

  • There can be little doubt that the two small ‘Islas sin Probecho’, sighted by the Spanish navigator Pedro de Unamuno on 28 July 1587 at 25�°N,69 are the Borodinos
  • The island of Amsterdam, which can be found to the west of Malabrigo on the maps of Quast, Martini, Sanson, and Nolin, according to Dahlgren appears for the first time on a map of 1635. It was still searched for unsuccessfully by Beechey in 1827 and is clearly a longitudinal

misplacement of Rasa, i.e. Okino-Daitō Shima

  • Doubtless the ‘Breskens-Eylant’ discovered on the Dutch expedition of Maarten Gerritszoon Vries (in the Castricum) and Hendrik Corneliszoon Schaep (in the Breskens) on 8 May

1643 at 24°43�'N and 151°31'�30"�E of Teneriffa (�135°01�'30"�E of Gr.), a low lying little island about c. 1.5 mylen (scarcely 2.8 km) long, is likewise identical with Isla Rasa, now Okino-Daitō¯ Shima (24°28'�N; 131°11�'E). On Quast’s chart, which was also used on the Vries expedition, the island of ‘Malabrigo’ [!] is situated 21 mylen to the west of ‘Breskens-Eylant’. In the ‘Daghregister’ of the Batavia port authority for 14 December 1643, on Vries’s voyage back, this discovery is called ‘Malabriga’

  • On an 1817 London chart, at c. 24°45�N; 134°10�E, is the entry ‘I. Dolores 1773’, which doubtless goes back to a sighting from a Spanish Manila galleon on her way from the Philippines to New Spain. We know that in 1773 the Spanish vessel Nuestra Sen˜ora de Consolación with Felipe Tompson as pilot sailed from Manila to California via New Guinea

On that voyage Helen Reef, Ngatik, and Oroluk in the Caroline Islands were sighted. Tompson’s southern route may not go against a sighting of the Daitos in the same year, but indicates that he initially tried to pursue the same course as his compatriot Francisco Antonio Maurelle seven years later, in 1780/81,77 a course which eventually was abandoned in favour of the traditional route.

  • On a trading voyage aboard the Felice from Whampoa (Canton) to the northwest coast of America, the British captain John Meares on 4 and 5 April 1788 sighted three islands, which were believed to be a new discovery and called the ‘Grampus Isles’. Notwithstanding

the considerable longitudinal difference of 14°30� and 14°55�30�, respectively, these Grampus Islands were Rasa (Okino-Daitō Shima) and the Borodinos (Minami-Daitō¯ Shima and Kita-Daitō¯ Shima)

  • Kendrick Island (24°35�N; 134°00�E) is a further longitudinal misplacement of Rasa. The earliest chart on which to find it dates from 1805. The name probably refers to either John Kendrick senior, who from the second half of 1789 until his death in December 1794 was busy in the maritime regions in question (further trading voyages of his vessel Lady Washington continued until 1796) or John Kendrick junior, who in July 1789 entered the Spanish service in Nootka Sound and as ‘Don Juan Kendrick’ ‘was sent to Spain in 1796 … had been a skillful pilot in the galleon service’. As John Kendrick junior was on the Northwest Coast for the fur trade (as a supercargo on the Eliza) in 1799, his active time in Spanish service, during which he could have encountered Kendrick Island,

is between 1789 and 1796. A contingent sighting must have taken place between the second half of 1789 and 1796, either on a trading voyage to or from East Asia or on the Manila galleon route from the Philippines to New Spain (Mexico)

  • According to Krusenstern, who refers to an Arrowsmith chart, the Bishop Rocks, lying at 25°20�N; 131°15�E, were discovered in 1796 or 1799 (the data are inconsistent) by Captain Bishop in the Nautilus. However, 1797 was the only year the Nautilus was east of the Ryūkyū Islands, on her way from Macao to Kamchatka (16 June — 25 August 1797).

It must have been during that voyage — any time between 6 and 31 July — that these rocks, presumably from afar, were sighted, which can be identified from their position with Minami-Daitō-Jima, if not both Minami-Daitō-Shima and Kita-Daitō-Shima (the Borodino Islands) as a whole were perceived as ‘rocks’

  • Another sighting of Rasa Island occurred on 8 May 1807, by Joseph-Ce´sar de Bourayne, commander of the French frigate La Canonnie`re, on the way from Cavite to Acapulco. The supposed discovery, whose position was fixed at 24°30�N; 130°18�30�E, was christened ‘Ile

de la Canonnière’

  • The Western names that stuck to the Daito Islands for more than 150 years were given in 1815 and in 1820: in 1815 Okino-Daito Shima was re-sighted by the last Manila galleon, the Spanish frigate San Fernando de Magallanes, and was called ‘Isla Rasa’, i.e. flat island; the

position was fixed at 24°26�'40"�N; 131°03'�46"�E of Gr; and on 20 June 1820 (st. v.; 2 July 1820 st. n.) Minami-Daito¯ Shima and Kita-Daito¯ Shima were re-sighted by the Russian Navy’s Lieutenant Sachar Ivanovicˇ Ponafidin, who called them (Ostrova Borodino, Borodino Islands) after his ship of the Russian-American Company. The positions fixed by him were 25°50�N; 131°12�E for the southern and 26°02�N; 131°15�E for the northern island respectively

  • ‘The brig Nile, of Boston, Captain [Robert Bennet] Forbes, in her passage from Canton to the Sandwich Islands, in August, 1825, passed two islands, the southernmost in lat. 25°42�N.; long. 131°13�E.; and the northern one in lat. 25°53�N.; long. 131°17�E. by good observations, and two chronometers’,87 clearly a re-sighting of the Borodinos.
