Strait of Tartary empires. Since the Manchus' rise to prominence in 1644, the name "Tartars" became applied to them as well, and Manchuria (and Mongolia) became known to the Europeans as the "Chinese Tartary". Accordingly, when La Pérouse charted most of the strait between Sakhalin and the mainland "Chinese Tartary" in 1787, the body of water received the name of the Strait (or Channel, or Gulf) of Tartary. In Japan, the strait is named after Mamiya Rinzō, who traveled to the strait in 1808 whereof the name was introduced by Philipp Franz von Siebold in his book "Nippon: Archiv zur Beschreibung von Japan"
