This compelling video chronicles the journey of Rina, known as Japan’s Tuna Princess, who made an extraordinary life change by moving from Niigata to Tokyo and shifting from a career in fashion design to become a professional tuna cutter. Now working at one of Japan’s most respected fish markets, Rina displays incredible skill, precision, and strength as she breaks down giant bluefin tuna—a process that requires not only technical expertise but also a deep respect for the craft and the product.

Rina’s story is an inspiring one of determination and passion. Breaking into the traditionally male-dominated world of tuna butchery, she has carved out her own space at Kitani Fisheries. The film follows her meticulous preparation process, from handling specialty knives to making clean, efficient cuts that maximize both yield and freshness. Along the way, viewers are offered a behind-the-scenes look at daily life inside a real Tokyo seafood market and a rare appreciation for the culture and tradition behind Japanese seafood cuisine.

The video also provides insight into the broader landscape of Japanese food culture, with glimpses of Tsukiji Market and the ongoing commitment among Japan’s chefs to honor their ingredients. If you are passionate about sushi, sashimi, or simply fascinated by the country’s vibrant seafood markets, this video highlights why Japan remains a world leader in both culinary tradition and innovation. For visitors, Tsukiji Fish Market (now primarily Toyosu Market, with many Tsukiji outer market stalls still open) is a must-see for food enthusiasts traveling in Tokyo.
