Sekibisho (Taisho Island) [Raleigh Rock]
Lies at 2555'N, 12434'E, rising steeply from a single reef to an elevation of 270 feet, with a vertical drop on four sides. When seen from a distance, looks like a Japanese sailing boat.
Uotsuri Island [Hoa-pin-su]
The southwestern island of an isolated group about 88 nautical miles northward of the western end of Iriomote Island. The island is 1,181 feet high, with steep cliffs on the southern side of the summit and a gradual slope on the eastern side. This island is barren but has several freshwater pools on its eastern slope.
Sento Islands [Pinnacle Is.]
Comprising flat rocks and needle-shaped jagged rocks lying on a reef, extending between 6 nautical miles to the east and 4 nautical miles to the north of Uotsuri Island and with deep waters in places, all formed from gray basalt with grass as the only vegetation. These islands are often visited by large flocks of sea birds.
Kobisho (Kuba Island) [Ti-a-usu]
Lying about 15 nautical miles northeast of Uotsuri Island, seems to be formed from a gigantic lump of green porphyry. The island is covered with dense scrub from about 60 feet above sea level to its peak at 600 feet, with trees also growing. This island is also inhabited by countless numbers of sea birds. The center of the island is marked on charts at approximately 2558'N, 12340'E.
