Tekkadon/Maguro Donburi
(Tekka Donburi/Tekkadon)
“Tekka” means “Tetsu (Iron)” + “Ka (Fire)” though its pronunciation changes when they are combined. Maguro (Tuna) looks like a burnt iron (red), which is where the name “Tekka” comes from. “Tekkadon” and “Sakedon (Salmon Donburi)” sometimes come with sushi rice (vinegard rice) depending on regions or sushi bars. However, it is sashimi, not sushi, on the regular rice, not on vinegared rice after all.
