Shiwaku Islands

Coordinates: 34°22′15.34″N 133°37′7.73″E / 34.3709278°N 133.6188139°E / 34.3709278; 133.6188139 The Shiwaku Islands (塩飽諸島 Shiwaku-shotō) or Shiwaku-jima (塩飽島) form an archipelago in the Japanese Inland Sea.[1]

The group is situated between Okayama Prefecture and Kagawa Prefecture in the western Bisan Seto and consists of 28 islands of various sizes. On the Okayama side lie the Kasaoka Islands. The name derives from shioyaku (塩焼く) or shiowaku (潮湧く) both meaning boiling seawater to get salt. However, the name may also refer to rough water created by the confluence of tides that mix around the islands.

History

Since ancient times, the islands have been an important point for maritime transport.[2]

Shiwaku Islands

Islands

Awa-shima

粟島, part of Mitoyo, populated. In Meiji 30 (1897), the National Mercantile Marine School was established here and subsequently many talented men were sent into the shipping industry.[3]

Benten-jima

弁天島, part of Marugame, unpopulated.

Budo-jima

歩渡島, This island is connected to Hitsuishi-jima. The name (歩 = walk, 渡 = cross) derives from the fact that it is possible to cross between the islands.

[Sanuki] Hiro-shima

広島, part of Marugame and one of the seven "salt boiling islands". area: 11.66 km², circumference: 18.5 km. Hiroshima is the largest of the Shiwaku Islands and is sometimes called Sanuki-Hiroshima to differentiate it from Hiroshima Prefecture on the main Japanese island Honshu. The China Sea Directory from 1873[4] contains a description of the island and recommends Enoura Bay (referred to as Ino Ura) as an anchorage:

‘The outline of Hiro Sima is very irregular, and its sharp rocky ridges are very conspicuous. The summit of the island, which presents southward the appearance of an almost perpendicular cliff, is 990 feet above the sea. On the south shore is Ino Ura, a small bay, on the shores of which are several small villages, the valleys around which are cultivated. The eastern hills are covered with brushwood, but the western ridges are thickly wooded. In the ravines, the sides of which are rocky precipices, numerous deer are found.

Ino Ura is a convenient anchorage for vessels passing through the Seto Uchi, and is generally chosen as a night anchorage, especially when bound from Hiogo to the westward, it being within convenient distance, and can be arrived at before nightfall. Care must be taken not to approach the shore too closely, as the head of the bay shoals very suddenly but good holding ground will be found here out of the strength of the tides.’

On the island is the grave of Frank Toovey Lake, a Victorian sailor who died here in 1868 while part of Richard Henry Brunton's survey party.
