Largehead hairtail (Tachiuo)

【Nigiri sushi: Shiromi
What is Tachiuo?
Tachiuo (Largehead hairtail) lives on the continental shelf along shores throughout Japan at depths of 100 to 200 m. Their bodies are remarkably thin, just like a Japanese sword and grow gradually thinner toward the back of the body, until the very end, which is like a string. The body is silvery white without any scales. Their torso length is over 1.3 m.

During the day they stay mainly in deep areas and then float up to shallower places at night to catch food. Tachiuo are very unique in how they rest. They swim in place vertically with their heads facing up. However, when swimming at full strength, they swim horizontally.

What does Tachiuo (Largehead hairtail) nigiri sushi taste like?
The taste of this fish differs depending on if it is served with or without the skin. The silver skin is full of flavor and is revered by the locals where it is found. But the skin is harder for larger fish and not everyone likes it. For that reason, the skin is sometimes seared when serving these days. When the fish is large with a lot of fat and in-season, it is a premium topping and the price is also extremely high.

Also called Atlantic cutlassfish or Band fish or Catlass fish or Cutlass fish or Japanese hair-tail or Ribband-fish or Scabbard fish or Silver eel or Silver fish or Snake fish.
