Dainichi Electronics President Kuroda hosts an annual banquet at his Karuizawa facility, serving sashimi from a tank-held white trevally. A guest claims the fish lacks freshness, prompting Yamaoka to agree and challenge Kuroda to a comparison using fresh stock. Yamaoka purchases a trevally, ensuring it is killed and bled immediately before packing it in ice. Both men prepare sashimi that evening. The guests unanimously prefer Yamaoka's dish, as he explains that fish caught directly from the ocean maintains superior health and condition compared to those kept alive in tanks for over a week.
