Cape Sōya, in Japan, is located 43 kilometres (27 mi) to the south, across La Pérouse Strait.

A Russian weather station, a lighthouse and a military base are all situated at Cape Crillon today.

Additionally, the cape is the Russian terminus of the proposed Sakhalin–Hokkaido Tunnel that would connect Japan and Russia by rail.

Having arrived at the Matsumae domain outpost of Shiranushi on the southern tip of Cape Crillon, he was directed by local Ainu to a place called Kogohau (コゞハウ) where the remains of rammed earth walls were found.

According to the Yuanshi, the general Yangwuludai (楊兀魯帶) crossed the sea and established frontier garrisons on Sakhalin.
