Abstract
The world conditions of petroleum industry was briefly discussed from the standpoint that Japan is apparently influenced by the international industrial cond-itions, as she has to import95% of crude oil refined in Japan.The Japanese refine-ries, although heavily damaged by raids during the war, were rapidly restored chiefly on the pacific coast by a help of foreign firms.At the end of1951, the daily capacity of the domestic refineries may ammount to100, 000bbl.and likely fulfil all domestic use of oils, except ariation gasoline and high-grade lubricant.To modernize these factories, however, was strongly hoped as well as an increase of modern tankers.
