This seems to be recurring problem in Japan's history. From WWII to now, Japan has imports the vast majority of its oil. And there has not been an alternative for japan.
| Country | Approx Share of Japan's Oil Imports |
|---|---|
| United Arab Emirates (UAE) | ~41% |
| Saudi Arabia | ~38% |
| Kuwait | ~7% |
| Qatar | ~5% |
| Oman | ~3% |
| Other countries | ~6% |
But what about Saudi oil?
