CHAPTER 3
THE DECLINE OF THE KAMAKURA
BAKUFU
INTRODUCTION
The 1260s marked the beginning of a decisively new period for the
Kamakura bakufu as it faced a set of increasingly complex problems
caused by changing conditions both at home and abroad.

The politi-
cal structure of the bakufu was about to undergo a major change after
1 I have used the following sources in writing this article: (1) the Azuma kagami, a history-
chronicle in diary format written from the viewpoint of the bakufu and covering the years 1180
to 1266. Nothing replaces it after that date. (2) The "Kamakura nendai ki" and "Buke nendai
ki"
are helpful, albeit partial, substitutes. I also used other diaries such as (3) "Kenji sannen
ki"
and "Einin sannen ki." These and other diaries can be found in Takeuchi Rizo, comp.,
Zoku shiryo taisei, 22 vols. (Kyoto: Rinsen shoten, 1967). For political conditions within the
bakufu, documents in (4) "Kanezawa bunko komonjo," which include letters exchanged
among members of the Kanezawa (H6jo) family, are important. The most inclusive document
collection for the Kamakura period is (5) Kamakura ibun, komonjo hen (thirty-six volumes to
date),
compiled by Takeuchi Rizo. Other sources such as (6) Kanagawa ken shi, shiryo hen,
vols.
1 and 2; and (7) Seno Seiichiro, comp., Kamakura bakufu saikyojo shu,j5, andge (Tokyo:
Yoshikawa kobunkan, 1970) are useful. A comprehensive description and i.idax to these and
other published documentary sources can be found in (8) pt. 2 of Jeffrey P. Mass, The
Kamakura Bakufu: A Study in
Documents
(Stanford,
Calif.:
Stanford University Press, 1976).
There is no index of this magnitude anywhere else. For the Kyoto side of Xa i.akura history,
diaries by nobles are important historical sources. The following are well kiiown for this
period: (9) "Kitsuzokki" by Yoshida Tsunenaga ?nd "Kanchu ki" by Fujiwara Kanenaka -
both in Sasagawa Taneo, ed., Shiryo taisei (Tokyo: Naigai shoten, 1937) - "Sanemikyo ki" by
Sanjo Sanemi (unpublished); and "Hanazono Tenno shinki" by Emperor Hanazono, in
Sasagawa, ed., Shiryo laisei. Historical chronicles such as the "Masukagami," "Godai teio
monogatari," and "Horyakukan ki" are also helpful. Many of the documents mentioned hers
are included in the fifth edition of (10) the Dai Nihon shiryo, though the volumes covering the
Kamakura era have reached only 1248. In the meantime, readers are referred to (11) Tokyo
daigaku shiryo hensanjo, ed., Shiryd
soran,
vol. 5 (Tokyo: Tokyo daigaku shuppankai, 1965).
Although there are many secondary works, the following are especially noteworthy: Miura
Hiroyuki, Kamakura jidaishi, vol. 5 of Nihon jidashi (Tokyo: Waseda daigaku shuppanbu,
1907,
1916), reprinted as Nihonshi no kenkyu, vol. 1 (Tokyo: Iwanami shoten, 1982) Ryo
Susumu, Kamakura jidai, jo, ge (Tokyo: Shunshusha, 1957); Sato Shin'ichi, "Bakufu ron," in
Shin Nihon shi koza, 7th series (Tokyo: Chud koronsha, 1949); Sato Shin'ichi, "Kfmakura
bakufu seiji no senseika ni tsuite," in Takeuchi Rizo, comp., Nikon
hokensei seiritsu
no kenkyu
(Tokyo: Yoshikawa kobunkan, 1955), pp. 95-136; Kuroda Toshio, "Moko shurai," Nihon no
rekishi, vol. 8 (Tokyo: Chuo koronsha, 1965); Amino Yoshihiko, Moko shurai, vol. 10 of Nikon
no rekishi (Tokyo: Shogakkan, 1974); Amino Yoshihiko, "Kamakura makki no shomujun," in
Rekishigaku kenkyukai and Nihonshi kenkyukai, comps., Koza Nihonshi, vol. 3 (Tokyo:
Tokyo daigaku shuppankai, 1970), pp. 21-56; and Nitta Hideharu, "Kamakura koki no seiji
katei," in Jwanami koza Nihon rekishi, vol. 6 (Tokyo: Iwanami shoten, 1975), pp. 1-40.
Though dated, Miura Hiroyuki's Kamakura jidaishi has not lost its value. During the postwar
period, Sato Shin'ichi's work led the field, and most recently, Amino Yoshihiko's "Moko
shurai" merits special attention as an innovative history.
