AUTHORITY CRISES 26l
in 748 and Koken was enthroned the following year, Tachibana no
Moroe continued on as minister of the left until 756, just a year before
Koken's abdication. Nevertheless, Nakamaro and his group were be-
coming stronger, mainly because of the power that Nakamaro held as
head of the office (the Shibi chudai) that handled the principal em-
press's (Komyo's) affairs. This office, standing outside the bureaucratic
structure defined in the Taiho administrative code, was staffed with
high-ranking officials who performed increasingly important func-
tions.
Its name, similar to that of a Chinese office administering the
affairs of state under Empress Wu at the turn of the eighth century,
suggests that Komyo - who supported, and was being supported by,
her ambitious nephew Nakamaro - was planning to rule Japan in the
Empress Wu manner. Because Nakamaro, as head of this office, was
taking responsibility for matters previously handled by the council and
the council itself now included an increasingly large number of officials
from the Fujiwara clan, Tachibana
no
Moroe's influence
was
in decline.
During the year
755,
rivalry between the two groups - one formerly
headed by Retired Empress Gensho supporting Moroe and the other by
Empress Komyo backing Nakamaro - came to the breaking point
when Moroe reportedly became bold enough at a drinking party to
criticize Empress Koken openly. Nakamaro and his party used the
incident
as an
excuse to press for Moroe's resignation. The situation
was
made even riper for intrigue and conspiracy when after Shomu's death
in 756, an edict was issued elevating to crown prince a person not
favored by the Fujiwara faction. Within
a
few
days
the Fujiwara leaders
retaliated. Two prominent heads of the anti-Fujiwara group were ar-
rested and placed in confinement on the charge that they had been
disrespectful to the reigning empress. In the following year, Tachibana
no Moroe died; a new crown prince (the future Emperor Junnin and a
Nakamaro relative) was appointed; and Nakamaro was given another
important extralegal ministerial position, that of
shibi
naisho.
But Nakamaro's control was not yet firm, as Tachibana no Moroe's
eldest son Naramaro was assembling support for a coup. Fujiwara no
Nakamaro soon got wind of the activity and hastened to stamp out
Tachibana's opposition force. He had the former Crown Prince
Funado executed and sent his own elder brother Toyonari (who had
been minister of the right) into exile at Dazai-fu. In an apparent
attempt to head off the popular discontent that had been aroused by
his ruthless elimination of
opponents,
Nakamaro decreased from sixty
to thirty the number of
days
a farmer had to work for the government,
halved the rice assessments, and reduced other forms of tribute. In
