The Taiji hunt, seen here during the 2014 season, has received widespread criticism
Japan has started its controversial annual dolphin hunt in the coastal town of Taiji.
The hunt sees the animals driven into a cove where some are slaughtered for their meat with knives in shallow waters.
Other dolphins are sold to aquariums and marine parks.
The Taiji hunt has been carried out for decades and gained global attention when it was the subject of the Oscar-winning documentary The Cove in 2009.
Japan this year also resumed catching whales for profit, in defiance of international criticism.

This year’s Taiji hunt kicked off on Sunday, but according to Japanese media the boats returned without any dolphins.
On Monday, the fishing fleet went out again to drive a dolphin pod towards the shore.
Environmentalists say the practice is cruel because the dolphins can take up to 30 minutes to die by suffocation or drowning.
But the fisherman from Taiji say the community’s livelihood is dependent on the trade.
The dolphin hunting season is expected to last for about six month.
Japan has already come under criticism this year for resuming commercial whaling after it left the International Whaling Commission (IWC).
Commercial whaling ships left port on 1 July this year and the first whales have already been killed and sold.
Under an IWC moratorium, whaling had effectively been banned since 1986.
Japan though had never fully stopped whaling – it has been conducting what it said were research missions killing hundreds of animals each year.
