What do the Japanese and Chinese with oil from killer whales?

There's no evidence that the Japanese or Chinese use oil from killer whales.

Here's why this is unlikely:

* Whale oil is not a common product: While whale oil was historically used for various purposes like lighting and lubrication, its use has been largely discontinued due to conservation efforts and the availability of alternative resources.

* Killer whales are protected: Killer whales are protected species in both Japan and China. Hunting them for any purpose is illegal.

* Cultural factors: While whaling was once a significant cultural and economic practice in Japan, it's now highly controversial. China, on the other hand, never had a tradition of large-scale whale hunting.

It's important to rely on reliable sources and avoid misinformation. If you're curious about historical uses of whale oil or the current status of whale conservation, you can find accurate information from reputable organizations like the World Wildlife Fund or the International Whaling Commission.
