The Japanese began to catch gray whales beginning in the 1570s. At Kawajiri, Nagato Province, 169 gray whales were caught between 1698 and 1889. At Tsuro, Japan, Shikoku, 201 were taken between 1849 and 1896. Several hundred more were probably caught by American and European whalemen in the Sea of Okhotsk from the 1840s to the early 20th century. Whalemen caught 44 with nets in Japan during the 1890s. The real damage was done between 1911 and 1933, when Japanese whalemen killed 1,449 after Japanese companies established several whaling stations on Korean Peninsula and on Chinese coast such as near the Daya bay and on Hainan Island. By 1934, the western gray whale was near extinction. From 1891 to 1966, an estimated 1,800–2,000 gray whales were caught, with peak catches of between 100 and 200 annually occurring in the 1910s.
