yes their have and use , like u say the oil very often in his culture for eat.
Japan kill more whales than any country and why? experiment? food? all that is shit , why their don´t eat like all human we do , chicken , pork , beef. we have enough of this animal , but not whales enough in 2011 for that hunt. Big sorry to japaneses , but i think you goverment have to think about it.
I can´t undestand how japaneses can be very respect with human and not with this animal.
