Oma Maguro

Oma town, jutting into the Tsugaru Strait at the northernmost tip of Aomori Prefecture, is renowned as one of Japan foremost sources of bluefin tuna. Raised in rough seas, the bluefin here stands out for its generous fat and the deep flavor of its lean meat. A single fish landed by pole and line is treated as something special even at market. The powerful taste of this tuna, found nowhere else, keeps drawing people back.

Highlights

Oma bluefin is famous for a traditional method in which fishermen catch each fish one at a time. Because the fish are handled with great care and never bruised, freshness and quality are preserved. Eateries near the port serve tuna landed that very day as sashimi or over rice, letting you enjoy the differences between cuts, from melting fatty otoro to firm and flavorful lean meat. A plate savored while overlooking the strait is truly exceptional.

Enjoying the Seasons

Bluefin is at its best in winter, when the fat is richest. In the biting cold the flesh firms up and the flavor grows deep and concentrated. Even so, many shops in Oma serve tuna year round, each season showing a different face. Summer brings light and refreshing lean meat, while winter offers otoro that melts on the tongue, so the impression changes with the time of your visit.

Access and Basic Information

Oma town is about two and a half hours by car from central Aomori City. From Hakodate it is roughly ninety minutes by ferry, making access from Hokkaido easy as well. Eateries serving tuna dishes dot the area around the port, and most grow lively around lunchtime. Popular shops sometimes sell out early, so visiting right after opening is recommended.

A Quick Tip

Take the first bite with nothing added. Once you have confirmed the natural sweetness and aroma of the tuna, add just a touch of soy sauce to make the quality of the fish stand out even more. Asking the local shop owner about the seasonal cut is a pleasure unique to Oma.
