Oma Tuna: The Ultimate Bite for Seafood Lovers in Tohoku

Oma, a small fishing town in Aomori Prefecture in Japan’s Tohoku region, is known nationwide for its premium bluefin tuna. Called the “black diamond of the sea,” Oma tuna is highly valued for its rich flavour and freshness, drawing chefs, gourmets, and foodies from around the world.
What Makes Oma Tuna Special
The fast, cold currents off Cape Oma create the perfect conditions for bluefin tuna, giving the meat its rich flavour and firm texture. The prized fatty cuts, like otoro, melt in the mouth and deliver a balance of taste that makes it one of the most sought-after cuts in Japanese cuisine.

In fact, this premium bluefin regularly fetches record-breaking prices at Toyosu Fish Market. But in Oma, it is a source of local pride and an important part of the community’s fishing tradition.
From Sea to Table: The Oma Tuna Experience
Visiting Tohoku is one of the best ways to experience the specialty at its freshest. In Aomori, many sushi shops and restaurants feature it in sashimi sets, sushi, and donburi bowls. Some even indicate the exact day the fish was caught, with tuna often brought in only hours before being served.

The prime season runs from autumn through winter, when the tuna reaches peak fat content and the flavour is especially rich. Pairing a slice with locally brewed sake is a classic combination and a must-try when you visit.
Planning a trip to the Tohoku region to experience this seafood delicacy? While Oma is best known for tuna, the region also offers hot springs, traditional festivals, and scenic coastlines.
