[Shimanto City, Kochi Prefecture] You can only eat this in Shimanto City!! "Salt-Seared Bonito" (Part 1)
When you think of delicious food from Kochi Prefecture, the first thing that comes to mind nationwide is the seared bonito known as "katsuo no tataki."
Katsuo is a famous specialty of Kochi, and as everyone knows, it actually has two peak seasons!
In this piece about the katsuo beloved by Kochi residents, Part 1 explains the timing and characteristics of each season, and Part 2 will cover recommended ways to enjoy it that you can only taste in Shimanto City.
〇 The seasons of katsuo: hatsugatsuo and modorigatsuo
Katsuo is a well-known specialty of Kochi, but its name changes with the fishing season (peak season) to "hatsugatsuo" or "modorigatsuo."
Here we introduce these two types of katsuo with different names, describing each season, their characteristics, and Kochi-specific recommended ways to eat them.
〇 Light-flavored hatsugatsuo!
Hatsugatsuo, loved since long ago as one of spring’s seasonal ingredients, originally referred to katsuo landed at the start of the year, as suggested by the prefix "hatsu" (first). In recent years, however, the term has come to mean katsuo landed from spring into early summer.
Juvenile katsuo hatched from eggs ride the Kuroshio Current northward around spring to seek food and grow into adults.
Katsuo landed during this northward migration are called "hatsugatsuo," also known as "noborigatsuo." The exact landing locations vary, but in Kochi the season runs mainly from spring to early summer (around March to May).
Young, fast-growing hatsugatsuo have translucent red flesh, a clean, springy texture, and a firm bite. They have less of the characteristic katsuo aroma, making them easy to eat even for those who are not fond of strong fishy smells.
Because hatsugatsuo is low in fat and light in flavor, it’s recommended to serve it as tataki together with the fatty skin. This is the season for the Nakamura-style salt tataki enjoyed with plenty of condiments. We will introduce Nakamura-style salt tataki in the next article, "Salt-Seared Bonito You Can Only Eat in Shimanto City!! (Part 2)."
〇 Rich-flavored modorigatsuo!
On the other hand, the katsuo that migrated north in search of food reaches southern Hokkaido, where falling water temperatures prompt them to head south again in search of warmer waters. Katsuo landed during this southward migration are called "modorigatsuo." In Kochi, the season is around autumn (September to November).
Because modorigatsuo feed heavily and are landed after growing large, they are rich in fat and are also called "toro katsuo" or "abura katsuo." They have long been cherished as an autumn ingredient.
The flesh of a large modorigatsuo is deep crimson in color, with fatty, pale areas near the skin and a rich, chewy flavor.
