Access to natural resources has long been a challenge for Japan (see e.g., World War II). According to a report by Alex Kimani for OilPrice.com, prior to the commencement of Operation Epic Fury, Japan was importing 90% of its oil from the Middle East (Saudi Arabia and the UAE its top suppliers). Moreover, approximately 95% of Japan’s oil imports passed through the Strait of Hormuz. The report notes that Japan is looking to diversify its oil supplies:

Japan is reaching out to suppliers in Central Asia, South America and Canada while negotiations with Venezuela, a former supplier, are currently underway. Following high-level discussions with the U.S., Japan is exploring a joint effort to boost Alaskan oil production. Japan plans to invest in Alaskan oil infrastructure, including investing in loading facilities to facilitate the transport of Alaskan crude, as part of a broader $550 billion bilateral investment program between the two countries. Oil from Alaska takes about 12 days to reach Japan, compared to over 20 days from the Middle East.

Sounds promising.
