Poronaysk, Sakhalin Oblast, Far Eastern Federal district, Russia

🇷🇺 Poronaysk is a town and the administrative centre of Poronaysky District of Sakhalin Oblast, Russia, located on the Poronay River 288 km (179 mi) north of Yuzhno-Sakhalinsk.

History It was founded in 1869 as a Russian outpost Tikhmenevsky near the Nivkh and Ainu settlements in the area. The Treaty of Portsmouth transferred it to Japanese control along with the rest of the southern half of the island of Sakhalin. It was renamed Shisuka (敷香町, Shisuka-chō), said to mean "Sisi Tukari (in front of the mountain)" or "Siika (big river)" in the Ainu language, remaining under Japanese control until the Soviet Army retook the whole of the island in 1945.

After the town had been granted to the Soviet Union, it was named Poronaysk in 1946, after the river on which it stands. The river's name is from Ainu poro nay, meaning "broad river", "big river", or "growing river". Various Japanese place names such as Horonai (幌内) share the same etymology with Poronaysk.
