Can you share an example? I wanna be blown away too hahahaha
Check Himawari. It's usually frozen there. Don't get it if it looks frostbitten, and it's usually fairly expensive.
I tried some super fresh from Tsukiji Fish Market two yrs ago that I still salivate about TO THIS DAY. And it was only $10 there for a big tray

Try it over rice though with furikake! You'll love it as a simple meal. It keeps forever in the fridge too. A little goes a long way (bc of the salt).
