Kōyasan

Kūkai's mountain, a walled-in monastic city on a high plateau in southern Kii, first settled in 819 (English Wikipedia).

It has three kinds of resident: the scholars (gakuryo), the practice monks and the wandering ascetics (Kōya hijiri), whose nembutsu preachers collect gifts for rebuilding all over Japan and are a main road by which Chōgen raised the Great Buddha at Nara [not yet checked against the source]. It has no soldiers' castles but holds estates in Kii and far away: the campaign board names Ōta-no-shō in Bingo, with the port of Onomichi, as the greatest of them. Its old quarrel is with Negoroji, the house of the reformer Kakuban, who was driven off the mountain by Kongōbuji's monks in 1140 [not yet checked against the source].

English Wikipedia (Mount Kōya) gives only the founding: first settled in 819 by Kūkai. Everything else here is recollection of the standard studies and the campaign board.

Overlord

none in law; patrons are the cloistered emperor and the court

What it holds

  • The mountain precinct and the Okunoin (Kūkai's mausoleum)
  • Estates in Kii, among them Ategawa [not yet checked against the source]
  • Ōta-no-shō in Bingo, with Onomichi as its port (see the Ōta and Onomichi records)
  • A network of branch halls and hijiri lodges in the provinces [not yet checked against the source]

How it was acquired

By Kūkai's founding, then gifts of the court and the great houses; Ōta-no-shō from Go-Shirakawa's circle in the 1160s or 1170s (the campaign board says a charter of 1169; not pinned).

Allies and rivals

Patrons: the cloistered emperors and the Fujiwara regents. Quarrel with Negoroji (Kakuban's line). Friendly with the Nara rebuilders through the hijiri.

How things stand that morning

A mountain at peace under its own rule. Hōjō Masako's memorial hall for Yoritomo (Kongōsanmai-in) is of 1211 [not yet checked against the source] and is not yet built.

Wealth

Estate rents (rice carried from Onomichi), offerings, the gifts the hijiri collect; no figure used.

Military

No warrior-monk record of the kind Hiei and Nara have is known to me for 1200; the later Kōya feuds belong to the 13th century and after.

Threats

  • Disputes over its distant estates with Kamakura's stewards (jitō); Ategawa's famous petition is of 1275 [not yet checked against the source] and is later

Places of note

  • Okunoin: Kūkai's mausoleum, the mountain's pilgrim heart

Where the sources disagree

Evidence: English Wikipedia (Mount Kōya) covers the founding only. The estates and the Negoro split are recollection.

On the map: Only the mountain is drawn here; the distant estates (Ōta-no-shō) are separate province records.
