There is a tsunami warning in Japan

The claim that there is a tsunami warning in Japan is substantiated by multiple reliable sources reporting on the aftermath of a significant earthquake with a magnitude of 8.8 that struck off the coast of Russia. The earthquake triggered tsunami alerts not only for Japan but also for other regions, including Hawaii and parts of the U.S. West Coast. Reports indicate that evacuations have been ordered in Japan as a precautionary measure against potential tsunami waves. The consistency across various news outlets regarding the issuance of tsunami warnings in Japan reinforces the validity of the claim. Therefore, it is accurate to state that Japan is currently under a tsunami warning.
