Inago no tsukudani is a traditional dish featuring insects as the key ingredient. It originates from the mountainous regions such as Nagano and Fukushima. The dish is prepared with rice grasshoppers or locusts that are cooked in a combination of soy sauce, mirin, and sugar, a method known as tsukudani.

Once prepared, the locusts should be crunchy, and the flavor is described as mild and nutty. The dish is often served as a snack with sake, beer, or tea, but it can also be served as an accompaniment to main dishes.
