However, at the start of the 20th century local traditions conflicted with modern whaling practices. In 1911 the conflict turned violent in Same Village, Aomori Prefecture. Ocean pollution from the whaling stations, including large quantities of oil and blood runoff, angered the local fishermen and threatened their own fishing grounds. In protest the fishermen burned a Toyo Hogei facility down. The people of the Same region also did not consume whales and considered them sacred.[40]
The League of Nations raised concerns about the over-exploitation of whale stocks and called for conservation measures in 1925. This eventually led to the Geneva Convention for the Regulation of Whaling which was presented in 1931 but did not enter into force until 1934 and was completely ignored by Japan and Germany.[41][42][43]
Basically, almost all the large whale populations in coastal Asia out of Japan's EEZ were collapsed by Japanese modern industrial whaling. For further information about status of whale species largely affected by Japanese whaling, see Wildlife of China.
