To showcase combined capabilities to deter and counter regional threats, U.S. Indo-Pacific Command aircraft conducted a bilateral exercise with Japan’s Air Self-Defense Force in the Sea of Japan. 

This exercise was conducted to demonstrate "our nation’s rapid reaction capabilities, high levels of force readiness, close coordination, bilateral interoperability, and credible deterrent capacity," said the U.S Indo-Pacific Command in a statement. This after China and Russia flew military aircraft in the Indo-Pacific during QUAD summit in Tokyo.
