THE BAKUHAN POWER STRUCTURE 153
Domainal productive capacity, as expressed in koku, was the first
and most easily demonstrated measure of the relative strength of the
several classes of daimyo.

Other factors such as geographical distri-
bution and control of strategic and economically valuable locations
were taken into account as well. The shogun's granary lands were
located in forty-seven of the sixty-eight provinces, accounting for
roughly a sixth of the country's productive base. If
we
add to this the
bannermen's holdings, the percentage rises to close to a quarter.
These holdings were heavily concentrated in the Kanto and the Tokai
provinces, but they also extended into central and western Japan. The
actual distribution of
tenryo
by region shows 1.026 million
koku
in the
Kanto, 687,000 in the capital area, 688,000 in the Tokai provinces,
1.353 million in the region north of the Kanto, 412,000 in western
Honshu and Shikoku, and 176,000 in Kyushu.

As
European visitors
to Japan in the seventeenth century commented, it was possible to
travel from Osaka to Edo without having to leave bakufu territory.
Not only was the
tenryo
well located to serve the tax need of the
bakufu, it also contained most of the important urban centers, such as
Edo,
Osaka, Sakai, Kyoto, Fushimi, Nara, and Nagasaki. The sho-
gun had also gained possession of the country's active silver and cop-
per mines. The bakufu, through its authority over the
tenryo
and the
fief lands of the bannermen, was directly in control of
a
commanding
section of the country, whether measured in terms of
land,
manpower,
commercial capacity, or institutional importance. But however large
the shogun's direct holdings, government under the Tokugawa house
remained a coalition between shogun and daimyo, as the term
bakuhan
reminds us.
To understand the several types of
daimyo,
their relationship to the
shogun, and the significance of their geographic distribution, we need
first to look back to origins.

There were, first, the self-made daimyo,
those who had come into existence before the appearance of Oda
Nobunaga. Among these were the Shimazu of southern Kyushu and
the Nabeshima of northern Kyushu, the Mori of western Honshu, and
the Satake, Date, Nambu, Mogami, and Uesegi in the provinces north
of Edo. These long-established houses had managed to survive the
wars of consolidation, in many cases holding on to their original do-
29 Harold Bolitho has cautioned that kokudaka
figures
were not a sure sign of daimyo power, nor
should one expect that these figures would hold constant throughout the era. See Chapter 5 in
this volume.

this volume.
