[Big fish] When I made mackerel swim, it caught a big fish. (2023/1/31)

Winter 2023.
Bluefin tuna can sometimes be caught in the Kanto region in January and February, but this may be the first year that individuals weighing over 100kg can be caught every day.
Strangely, on January 31st, many bluefin tuna began to appear off the coast of Izu. Will good luck come to me and my senior, who happened to be on a boat targeting tuna? !
