A Chinese fishing trawler collides with two Japanese Coast Guard patrol boats in disputed waters near the Senkaku Islands.

The 2010 Senkaku boat collision incident occurred on the morning of September 7, 2010, when a Chinese trawler operating in disputed waters collided with Japanese Coast Guard (JCG) patrol boats near the Senkaku Islands. There were several JCG boats involved, including Yonakuni and Mizuki, which collided with Minjinyu 5179, plus Hateruma and other JCG boats.

The Senkaku Islands, known as the Diaoyu Islands in China and the Tiaoyutai Islands in Taiwan, are a group of uninhabited islands in the East China Sea, administered by Japan. They were historically known in the Western world as the Pinnacle Islands. The islands are located northeast of Taiwan, east of China, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands.
