Eating the eggs of fish
Sep 15th, 2009 by Ad Blankestijn
The egg masses of fish or their ripe internal ovaries are called roe (gyoran). Both raw and cooked, roe is a popular food in Japan. We find the following types:
- Ikura orĀ salmon roe. The term is a loan word from the Russian ikra, caviar. Although not as precious as its Russian namesake, the bead-like ikura-spheres have a beautiful orange color and taste delidiously. Ikura is popular sushi topping and is also used in chirashi-zushi and onigiri.

- Kazunoko or herring roe, usually salted. Kazunoko is yellow and has a firm, rubbery texture. The roe is flavored with soy sauce before eating. Besides being a topping for sushi, kazunoko also is a popular item in O-sechi Ryori, the special New Year’s meal.

To complete the (Edo-period) list of the “Three Great Delicacies (chinmi)”, to uni and kazunoko should be added konowata, although this is not a roe. Konowata are the fermented intestines of the sea slug (namako). All three delicacies are served as food with sake.
