(d) Petroleum.
The known petroleum producing basins of Japan are strung out in
a belt more than 600 miles long along the northwestern coast of Honshu and in the
west central part of Hokkaido. The major producing basins are those in Honshu and
include the Akita, Yamagata, and Niigata. A small producing area is in Shizuoka
Prefecture at Sagara on the Pacific coast of Japan, southwest of Tokyo.
There are 76 oil fields, nearly one-half of which are abandoned or
produce an insignificant amount of oil. These have an estimated proved reserves of
105,411,000 barrels, 80 percent of which is expected to be derived from ten fields. In
prewar years, the crude oil production of Japan proper supplied only a small part of
the nation's petroleum requirements (about one-eighth of civilian requirements)
