I had this bonito 2 years ago. Modori-gatsuo. Normally Bonito, Katsuo season is summer. They are coming from south to north.
Then, they are coming back from north to south in winter. So, we say Modori-Gatsuo, coming back bonito.
We can say return bonito but return is not good word, maybe.
It is well fat and tasty. You can eat this fish on Sushi Day, November 1st.
You can see the size. I compare with Kinme-Dai.
SUSHI DAY is coming on November 1st. Thusrday. You can get 30% of your dining coupon.
