Why Is Otoro Tuna So Expensive?

Otoro tuna, the most prized part of the bluefin tuna, is renowned for its rich flavor and buttery texture, making it a sought-after delicacy in sushi cuisine. The high price of otoro tuna can be attributed to several factors. First, the rarity of this cut plays a significant role; it comes from the fatty underbelly of the fish, which comprises only a small portion of the entire tuna, making it scarce. Additionally, bluefin tuna itself is rare and increasingly difficult to source due to overfishing and strict regulations aimed at preserving dwindling stocks. The demand for otoro, especially in high-end sushi markets in Japan and globally, further drives up its price. The meticulous preparation and skill required to handle this delicate cut also contribute to its cost. Furthermore, the sustainability efforts and ethical fishing practices necessary to ensure the bluefin tuna's survival often result in higher operational expenses, which are passed on to consumers. As a result, otoro tuna remains a luxury item, reflecting both its exceptional culinary qualities and the environmental challenges associated with its procurement.

What exactly is otoro tuna?

Otoro tuna is the richest cut of bluefin tuna, sourced from the belly of the fish, typically near the head. It should not be mistaken for chutoro, another belly cut that comes from the rear section of the fish.

Tuna has been highly regarded in Japanese cuisine since the Edo period. Interestingly, toro tuna was once discarded rather than appreciated. The exact moment when these fattier cuts began to be valued is unclear, but eventually, people recognized that they offered a deeper, umami flavor absent in leaner cuts.

This realization, along with the growing popularity of sushi worldwide, has driven up the price of otoro tuna significantly. Unfortunately, this surge in demand has contributed to overfishing of bluefin tuna, making various cuts, including otoro, increasingly scarce and expensive. Consequently, many have started to seek alternatives like salmon belly or yellowtail.
