Final answer:
Japan has historically been heavily dependent on oil imports from the Persian Gulf region, including countries like Kuwait.
Step-by-step explanation:
It is difficult to determine the exact percentage of Japan's oil that comes from the Persian Gulf, as oil imports can vary over time. However, historically, Japan has been heavily dependent on oil imports from the Persian Gulf.
During the 1970s, the oil boom in the Persian Gulf region widened the gap between the rich and poor in Iran. While specific data on Japan's oil imports from the Persian Gulf is not available, it can be assumed that a significant portion of Japan's oil imports come from the region.
Kuwait, one of the countries in the Persian Gulf, exports oil to Japan. In 2017, Kuwait's four largest export partners were South Korea, China, Japan, India, the United States, and Singapore. China is Kuwait's number one source of imported goods, with the United States coming in second. This suggests that Japan imports a considerable amount of oil from the Persian Gulf region.
