Why is "Okhotsk culture" trending?

Wikipedia Overview

The Okhotsk culture is an archaeological coastal fishing and hunter-gatherer culture that developed around the southern coastal regions of the Sea of Okhotsk, including Sakhalin, northeastern Hokkaido, and the Kuril Islands during the last half of the first millennium to the early part of the second. The Okhotsk are often associated to be the ancestors of the Nivkhs, while others argue them to be identified with early Ainu speakers. It is suggested that the bear cult, a practice shared by various Northern Eurasian peoples, the Ainu and the Nivkhs, was an important element of the Okhotsk culture but was uncommon in Jomon period Japan. Archaeological evidence indicates that the Okhotsk culture proper originated in the 5th century AD from the Susuya culture of southern Sakhalin and northwestern Hokkaido.
