544 COMMERCIAL CHANGE AND URBAN GROWTH
Another factor was the institutionalization of
the
system of alternate
residence. Although the custom of personal attendance on one's supe-
rior and the submission of hostages as an expression of loyalty had
become fairly common during the sixteenth century, these practices
were made a permanent obligation for the daimyo only after 1633.
From that date, daimyo were compelled to alternate their residences
between Edo and their home domains, to build elaborate mansions in
Edo,
and to leave appropriate retinues, including their wives and
children, permanently in the shogun's city. This system was designed
to permit the shogunate to maintain a close surveillance over the
daimyo, but it also had the consequence of stimulating the nation's
volume of commercial exchange as the daimyo processions moved
back and forth along the new highways that crossed Japan.

The growing wave of commercial transactions had several important
consequences. Agricultural patterns changed enormously, for now
farmers were able to concentrate more profitably their energies on
growing commercial crops, such as cotton, tea, hemp, mulberry, in-
digo,
vegetables, and tobacco, for sale to the urban markets.
40
Re-
gional specialization also became a feature of economic life, as great
numbers of villagers around Osaka, for instance, started to switch over
to cotton cultivation while farmers in northern Japan began to raise
horses and cattle for sale as draft animals.
41
Individual rural house-
holds began to develop by-employments or simple rural industries, so
that even within a single domain certain villages became known for
their production of goods such as paper, charcoal, ink, pottery, lacquer
ware, or spun cloth.
Concurrent with the commercial growth of Tokugawa Japan was the
daimyo's increasing need for cash revenues, which could come only
through participation in interregional trade. One part of the story is
simply that the daimyo needed money to buy the growing number of
specialized goods that were produced outside their own domains. But
the system of alternate residence also put a strain on the daimyo's
finances. The experience of the Maedo daimyo of Kaga was fairly
typical. By the end of the seventeenth century, their journeys to Edo
