Ojika Seto is the strait south of Uku sima and Tera sima. In the centre of this strait is a small rock named Ai-no se, 16 feet above high water, having deep water round it. The width of the western entrance of this strait between Tera sima and No sima is 9 cables, but isolated dangers exist nearly one cable to the northward of No sima.
Mu sima, 254 feet high, half a mile wide and circular in shape, lies a little over one mile from the south end of Uku sima. The north, south, and west sides of Mu sima are steep-to, but shoal water extends one quarter of a mile to the southward of its eastern point.
There is a small islet, 28 feet high, having a single tree on its summit, situated just off the west part of Mu sima. Directions. In entering Ojika seto from the eastward, pass Kuromo ze on either side, and steer to the westward between Uku sima and Mu sima; the summit of Hoage in line with the south end of Ai-no-se, bearing W. by S., leads 3 cables from the south shore of Uku sima, and when the noth point of Tera sima is seen just open to the westward of Uku sima west point, N.W. W., steer towards it, which will lead into Kono ura, when proceed to an anchorage as before directed. But if proceeding through the Ojika seto from the eastward, after passing Ai-no-se, steer to the westward with Kuromo ze summit seen well open to the northward of Ai no se, bearing E. S.; this mark on astern leads through the centre of the channel between Tera sima and No sima; Tera sima can be passed at 12 cables distance, but No sima must be given a wide berth, and when passing the northern point of No sima the summit of Kuromo ze should not be seen south of Ai-no-se.
In entering the Ojika seto by the channel south of Mu sima, keep the eastern point of Nosaki sima in line with the point west of Eno sima bearing S.S.E. E. and steer N.N.W. W., which will lead clear of Kebuta (see below); and when the north extremes of Kuromo-ze and Mu sima are in line, E. by N. N., steer N.W. W., which will lead one-third of a mile north of Ai-no-se, and when Ai-no-se bears S.S.E. steer N.N.W. for the anchorage in Kono ura.
In entering Ojika seto by the channel between Nosaki sima and Ojika, remember that Nosaki sima is steep-to, but in passing the south-east point of Ojika care must be taken not to bring the north end of Nosaki sima to the eastward of N.N.E.; the north-east point of Ojika should be given a berth of at least a quarter of a mile, and after passing it, steer towards Ai-no-se, leaving that rock on either side, and if intending to anchor in Kono ura, proceed as before for the anchorage. Nosaki sima, 1142 feet high, one mile south of Mu sima, is 33 miles long north and south, with hills extending through the centre, the summit being over the northern portion; in the middle of the island is a saddle about 200 feet high.
The western part of the northern point of Nosaki sima is densely wooded, and on the west side of the island, immediately under the summit, is a remarkable reddish coloured landslip.
The channel between the south-east point of Nosaki sima and Nakadon is 22 cables wide and clear of danger. Deer and pheasants abound in Nosaki sima.
Eno sima, 89 feet high, is a small islet, steep-to all round, lying a quarter of a mile from the north-east shore of
Nosaki sima.
Kebuta are two dangerous rocks, having less than six feet water, lying near each other, 1 cables north of the north extreme of Nosaki sima, with Eno sima summit bearing S.E. and the south end of Mu sima E. by N. & N.
The eastern extreme of Nosaki sima in line with the point abreast Eno sima, bearing S.S.E. E., leads 14 cables to the eastward of Kebuta; a bare hill, 193 feet high, over the north point of Ojika seen open a quarter of a point to the northward of the north-east extreme of Ojika, W. 1 S., leads i cables to the northward, and the south-east extreme of Ojika, S.W. † S., leads 1 cables to the westward.
Ojika island, which forms the south side of Ojika seto, is 3 miles long East and West, and 24 miles broad, it is separated from Nosaki sima by a navigable channel three-quarters of a mile wide. Off the southern and western portions of Ojika are several lands, the westernmost being 10 miles distant. The narrow channel formed by the islands adjacent to Ojika are only or arall vessels. On the east side of Ojika there are two conical hills, having clumps of trees on

is a hill 265 feet high, the south side of which rises perpendicularly from and the hills are 348 to 263 feet high, with e, bare hill over the northern point, e sea on its west side.
East bay, on the eastern shore of Ojika, is three-quarters of a mile deep, and nearly 7 cables wide at its entrance. The shore of this bay is fronted with shelving rocks that cover at high water; from Tonozaki, the south entrance point, rocks extend 2 cables in a northerly direction, and shallow water half a mile in a south-easterly direction. Kuszukuri, the north entrance point, is marked by a rock above water at the extremity of the shelving rocks.
The depths in East bay are from 4 to 14 fathoms, the best anchorage being in about 8 fathoms, with the north point of Nosaki sima in line with the rock off Kuszukuri point, bearing E. by N. N.; and the south end of Nosaki sima in line with Tan-ji islet, S.S.E. E.
Directions. Entering East bay from the southward, keep the west extreme of Shimomu sima in line with the north point of Nakadori sima, bearing S. by E. E.; this mark leads clear of the shoal water off Tonozaki, and when the north point of Nosaki sima bears N.E. a N.W. by N. course will lead to the anchorage.
From the south-westward when approaching Tonozaki point, the north extreme of Nosaki sima should not be brought to the eastward of N.N.E. until the west point of Shimomu sima is in line with the north point of Nakadori sima, bearing S. by E. E., when proceed as before.
From the northward, keep the east point of Nosaki sima in line with the point abreast of Eno sima, bearing S.S.E. & E., until the south-east point of Ojika bears S.W. S., then steer to the southward, keeping midway between Ojika and Nosaki sima, and when the centre of a smal' reddish coloured landslip on Nosaki sima bears E. N. steer W. S., until the hill over the north side of the bay bears N.N.W. W., when a N.W. by N. course will lead to the anchorage.
The north-east point of Ojika should not be approached nearer than a quarter of a mile.
Ko-guro sima, 57 feet high, situated 64 cables westward of the south-east point of Ojika, and 2 cables from the shore; is 400 yards long East and West, and 300 yards broad. This island is steep-to, except off the north-east point.
Anchorage can be obtained nearly midway between Ko-guro sima and the south-east point of Ojika, in 7 fathoms, sand, with the south extremes of Ko-guro sima and Kuro sima in line, bearing W. by S. S., and the hill over the south-east point of Ojika N.N.E. ‡ E. This anchorage is sheltered from northerly winds, and the depths are even.
Kuro sima, 140 feet high, half a mile westward of Ko-guro sima, has a wooded peak over its east and west ends, both of which rise precipitously from the sea, the dark cliffs being remarkable from the southward and westward. This island is nearly half a mile long east and west, and a quarter of a mile broad, having on its south-west extreme a pinnacle rock, 31 feet high; the southern side is steep-to, but the channel on the north side, which is one cable wide, has only 4 to 10 feet water.
U-u-sima, 172 feet high, 7 cables to the westward of Kuro sima, is nearly 800 yards long, and bare.
O sima, 349 feet high, a quarter of a mile westward of U-u-sima, rises perpendicularly on its north-west side; on it summit is a large clump that shows out conspicuously from the southward and westward. The south side of C ́sima is steep-to, but its rocky ledge extends some distance from the south-west side, with shallow water between it and Mutsz-se, a cluster of small rocks, three-quarters of a cable in extent, and 5 feet above water, half a mile south-west of O sima.
