Key point in the article is this:

On a visit to the former Tsukiji fish market area in downtown Tokyo, Yuuka Fujikawa from Hokkaido, said she has hardly seen whale meat sold at supermarkets. “I’ve actually never tried it myself,” she said.

I've never seen it in the supermarket and I've only seen whale meat at a restaurant once (whale bacon, it was called, and it was literally fishy bacon. I can see why nobody is fucking buying that shit)

The industry is dying (rightfully) and you have a bunch of people trying to keep it afloat.
