The provincial seat (kokufu) of Ōsumi, at Kokubu. Ōsumi is the south end of Kyushu with the volcano of Sakurajima across the bay; Kokubu stands at the head of Kagoshima bay.
Tane and Yaku are its islands. The Shimazu are its constables by house tradition (Shimazu Tadahisa). As everywhere in 1200 the governor (kokushi) is a courtier named by the court, often a favourite of the cloistered emperor or of a regent house, who may never go; his deputy (mokudai) and the local officials (zaichō kanjin) keep the office, and the revenue is divided among the governor, the proprietors of the estates and, where one is named, the Kamakura constable (shugo) and stewards (jitō) who keep the peace.
The Chinese grid of the compound has mostly returned to fields [not yet checked against the source]. The governor's name for 1 January 1200 is not known.

Where the sources disagree
Evidence: The campaign board entry and recollection; the site of the kokufu in 1200 is not pinned.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: Placed on the campaign board's or the gazetteer's site; the kokufu of 1200 lay within a few kilometres.
