Province, circuit or island group · The chiefs of the Ryukyu islands · as at first light, 1 January 1200

Amami Ōshima

The largest island between Kyushu and Okinawa.

The Japanese court claimed the Kikai islands in 998 (the Dazaifu orders of that year) and Yoritomo sent men to pacify Kikaigashima in 1188 (English Wikipedia, Kikai Island); the claim had no lasting effect. The island's Kamuiyaki stoneware (11th to 14th century) is made on neighbouring Tokunoshima. No lord is known for 1200.

Who holds it

Name
not known for 1 January 1200
Title
Local chiefs; no outside lord holds it
Confidence
low

No source names a chief or an officer for 1200; the evidence is archaeology and a few Japanese notices of 1187 and 1188 (see the Ryukyu realm record, Ryukyu).

Overlord

none known; the Dazaifu (998) and Yoritomo (1188) claimed it and the claims lapsed (Ryukyu)

How things stand that morning

No outside lord holds it; claims by Dazaifu and Yoritomo lapsed.

Where the sources disagree

Evidence: The campaign board entry and recollection; no province-level source for 1200 was reachable.

"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.

On the map: Drawn from the modern units round the places named. These islands were never a province of Japan: the group is a convenience of the map, not a division of 1200, and the edges follow the units.

Primary sources for Ryukyu
