The slaughter of dolphins in Japan is NOT a traditional culture.

These are motor boats. There is nothing traditional about motor boats. Tradition enters into an fishing when the 'chance' of catching a marine mammal equates to when it was done long ago. 

Besides that not all these dolphins are used for consumption. There are many dolphins SOLD for a lot of money. That has absolutely NOTHING to do with tradition.

The United States is sensitive to Aboriginal Hunting. There is an Alaskan tribe that hunts their native waters for whale. They take what they will use in the village that year and use traditional methods for their hunt.

The American Native tribes don't use factory ships either. Everything is done by hand with the involvement of the entire village.

Alaska's three-member (click here) congressional delegation says the International Whaling Commission has extended catch limits of bowhead whales for Alaska Eskimo subsistence hunters.
The six-year extension was approved Tuesday at the IWC's annual meeting, which is taking place in Panama City this year. 

The current Alaska bowhead limits were set to expire at the end of the year.
A statement released by the Alaska Eskimo Whaling Commission says the IWC adopted catch limits allowing Alaska and Russia Native hunters to land as many as 336 bowhead whales from 2013 to 2018.

The AEWC says annual limits adopted are the same as they have been for the past 15 years. 

Under the current 2012 bowhead quotas, 75 strikes were distributed among 11 Alaska whaling villages and seven were allocated to Russia's Chukotka Natives.

Japan is practicing the slaughter of an endangered species. It has nothing to do with traditional anything.
