broiled eel over rice in a lacquered box
A classic Japanese dish; the eel is grilled with a sweet soy-based sauce and served in a rectangular lacquered container (jūbako).
Let's have unajū for lunch today.
The unajū from the long-established restaurant was fragrant and exquisite.
Full kanji spelling; 鰻 is not a jōyō kanji, so the mixed form is more common.
A clipping of 鰻 and 重, where 重 denotes an eel-and-rice dish served in a lacquered 重箱.
