The Taiji dolphin drive hunt is a dolphin drive hunt that takes place in Taiji, Wakayama in Japan every year from September to March. According to the Japanese Fisheries Research Agency, 1,623 dolphins were caught in Wakayama Prefecture in 2007 for human consumption or resale to dolphinariums, and most of these were caught at Taiji.
The annual dolphin hunt provides income for local residents, and has received international criticism for both the cruelty of the dolphin killing and the high mercury levels of the dolphin meat.
Residents of Taiji have been refining whaling techniques and have had significant whaling operations since the early 17th century, and became known as a center for whaling in 1675. Hunting dolphins for commercial purposes in Taiji continues. In 2008, 1,484 dolphins and whales were caught, while fisherman planned to catch around 2,400 in 2009. Some of the dolphins are sold to aquatic parks, instead of slaughtered, and Ted Hammond is one of the main brokers for Taiji.
In Japan, the hunting is done by a select group of fishermen. When a pod of dolphins has been spotted, fishing boats move into position. One end of a steel pipe is lowered into the water, and the fisherman aboard the boats strike the pipe with mallets.
This is done at strategic points around the pod, in an effort to herd them toward land. The clamor disrupts the dolphins' sonar throwing off their navigation and herds them towards the bay which leads to a sheltered cove. There, the fishermen quickly close off the area with nets to prevent the dolphins' escape.
As the dolphins are initially quite agitated, they are left to calm down over night. The following day, fishermen enter the bay in small boats, and the dolphins are caught one at a time and killed. The primary method of dispatch was for a long time to cut the dolphin's throat, severing blood vessels, and death was due to exsanguination.
The government banned this method and now the officially sanctioned method requires that a metal pin be driven into the cervical region ("neck") of the dolphin, severing its brainstem, which causes it to die within seconds, according to a memo from Senzo Uchida, the executive secretary of the Japan Cetacean Conference on Zoological Gardens and Aquariums.
