Echigo

Echigo is the long province on the Japan Sea from the Shinano border to Dewa, with the Niigata plain, the Shinano river and Naoetsu.

The Jō, a Taira family, hold lands in the north (Aga-kita); Kamakura has stewards and a constable (not named) in the south. On the likely course the Jō revolt of 1201 tests the regime here.

Who holds it

Title
Governor of Echigo (court appointment; possibly Kamakura's nominee)

How things stand that morning

What Kamakura names or controls: Thin to moderate: stewards, an unnamed constable; Echigo may be in the group of provinces whose governors Kamakura names (recalled, not pinned). What stops it: The Jō, the court's governor and the temples' estates.

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

Where the sources disagree

Evidence: Recollection, the brief and the campaign board; no list of governors or constables for 1200 was opened.

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

On the map: A rough outline from the modern prefecture; the old province's edges differ in places.
