Do not believe. I didn't think such a delicious fish was popular... Besides, tuna was too popular even in the Edo period, and the Toro part was left out. It is said that even the skinny parts are pickled and eaten. It can be said that the popularity of tuna as it is today is relatively new.
I will immediately start working to regain the popularity of the tuna. Koch and Wo removed from Smartphone. Then another crew member was called.
"Okay, take a closer look. The important thing is to get the blood flowing. I want to take the time to drain the blood properly but this time I don't have time so I'll go easy. Then you guys ask Koch, Wo." (Rei)
"First, stick a knife into the brain and insert this wire from there to remove the nerves. Then insert the knife and remove the two upper left and right halves of the gills. Also, remove the lower gill bases. A lot of blood will come out, so keep pouring seawater." (Koch)
