At Kappa Sushi, a "book tuna gift campaign" is being held. The application period is from August 1st to August 31st.
This is a WEB campaign where if you answer a quiz on a special site and apply, you will win a whole tuna per person by lottery. It is said that a powerful fish body of about 160 cm will be disassembled in front of the winners and presented in a fresh state.
