Michichika

The most powerful man in Kyoto.

A courtier of the Murakami Genji who rose by serving the cloistered emperors, he helped Go-Toba to the throne in 1183, managed Yoritomo's visit to the capital in 1190, took charge of Princess Senyōmon-in's Chōkōdō estates after Go-Shirakawa died in 1192, overthrew the regent Kujō Kanezane in 1196 and put Konoe Motomichi in his place, forced the enthronement of his adoptive grandson in 1198, and in 1199 survived a plot of Kamakura's man in the capital. He has been Naidaijin since the summer of 1199. His power rests on his relation to Go-Toba, on the child emperor, and on the good will of Ōe no Hiromoto and the Kamakura clerks, who backed him in 1199 (English Wikipedia).

Overlord

Go-Toba

What it holds

  • Management of the Chōkōdō estates (Senyōmon-in's) for Go-Toba's side
  • The Tsuchimikado mansion, where the emperor was born
  • The Koga family's estates and the household of his sons
  • The offices of the right guard and the Naidaijin

How it was acquired

By a thirty-year career at the cloistered courts and by the coup of 1196.

Allies and rivals

Allied with Go-Toba and with Ōe no Hiromoto's Kamakura clerks; enemies: the Kujō house (Kanezane, Yoshitsune), Ichijō Takayoshi (who is said to have plotted against him in 1199), the nurse Kenshi's circle on the question of the crown prince.

How things stand that morning

At the height of his power, fifty years old by Western count. On the likely course he becomes Morinari's tutor later in 1200 and dies suddenly in the autumn of 1202.

Wealth

Offices, the Koga estates and his management of the Chōkōdō block. No figures used.

Military

No troops of his own; he relies on Go-Toba's guards and on the Kamakura clerks.

Threats

  • The Ichijō and Kujō bloc, who are in-laws of Yoritomo's house
  • The rise of Kenshi and of Morinari's party
  • His own health: on the likely course he dies in the autumn of 1202

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.

In 1200

  1. Shōji 2 (1200)Becomes tutor to the new crown prince Morinari (English Wikipedia)Depends on: Go-Toba's choice of Morinari Stopped by: A reversal by Go-Toba

Later, on the likely course

  1. Kennin 2/10/21 (about 7 November 1202 Julian)Dies suddenly, aged about 53Depends on: Natural death; no cause reported in the page Stopped by: n/a

Places of note

  • Tsuchimikado mansion: His house on Tsuchimikado street, site of the emperor's birth [not yet checked against the source]

Where the sources disagree

  • The English Wikipedia page names Ichijō Yoshiyasu in the 1199 plot; Yoshiyasu died in 1197, so Takayoshi is meant (brief).
  • The page gives his age at death as 54 in the text and 52-53 in the infobox; we use 'about 53'.

Evidence: One English Wikipedia page with many dated points; the details of the 1199 plot are not in it.
