468 POLITICS IN THE EIGHTEENTH CENTURY
Against this, Tanuma's old supporters were still strongly entrenched
in important posts. Matsudaira Yasuyoshi still served as senior coun-
cilor and Mizuno Tadatomo as the titular senior councillor (roju
kaku).
Faced with this much opposition, Sadanobu petitioned the
heads of the Kii, Owari, and Mito branches of the Tokugawa house
for some additional sign of official approval to help him implement
his reform program. This petition had some success, although not as
much as he would have wished. He had in mind promotion to grand
councilor but had to settle for the ancient position of shogunal ad-
viser (hosa), a post unfilled for more than 150 years. Once this step
had been taken, early in 1788, both his major opponents, Mizuno
and Matsudaira, resigned from the Senior Council, to be replaced
with Sadanobu's own friends - Matsudaira Nobuakira as senior coun-
cilor, Honda Tadakazu as chamberlain, and Toda Ujinori as superin-
tendent of temples and shrines. These changes gave Matsudaira
Sadanobu the commanding position he needed inside the bakufu and
the shogun's own household. With this base and the support of the
three cadet daimyo, as well as Ienari's father Hitotsubashi Harusada,
Sadanobu could now begin his own reforms.

Of all the manifold problems confronting him, the legacy of social
chaos left by the events of the last years of the Tanuma period was the
most disturbing. To cope with this, Sadanobu believed it necessary to
rebuild the entire social system, to restore morale, and to revive the
economy, and all as quickly as possible. In particular, the problem of
the bakufu's own samurai retainers, now largely demoralized, called
for urgent attention. To restore morale, the government exhorted the
samurai to improve their general behavior and encouraged them to
devote themselves to scholarship and to training in the martial arts.
The administration also promised to identify men with the necessary
skills and qualities to take charge of such a program, and so orders
went out to promote even subordinate, low-ranking samurai who
might be considered for such responsibilities.
Then, in mid-1790, the government issued the Igaku no kin (Prohi-
bition of heterodoxy). The administration believed that the orthodox
Chu Hsi philosophy espoused by Tokugawa officials for nearly a cen-
tury and
a
half had been undercut by new philosophies.
