Why is Oma Tuna so popular?

Oma Tuna is considered one of the best tuna available in Japan. The reason behind this lies in the geographical features of the area and fishing method of the Oma Tuna.

Oma Tuna is found about 5 kilometers away from Cape Oma. This area is where three different currents meet, bringing high quality plankton into the water. The plankton are eaten by pacific saury, which are the Oma Tuna’s favorite food.

While most tuna are fished with a round haul net, Oma Tuna is fished by pole fishing. The fishing lines used are only 2 millimeters in diameter. The pole fishing technique is used during the day, and at night, the line fishing technique is used. About 3,000 hooks are attached on a 200-kilometer rope.

These two techniques allow for the tuna to be caught with minimal damage and scarring. This also allows for a fast blood-extracting procedure, which allows the tuna to maintain its freshness.

When is Oma Tuna in season?

Oma Tuna season is between August and January. Tuna-fishing is especially thriving during the autumn and winter months, when the water temperature decreases.
