Hokuriku Fermented Tourism #1 – Mackerel Heshiko-Narezushi
Mackerel fishing was once popular in the village of Tagarasu in Obama City, Fukui Prefecture, located in the depths of Wakasa Bay.
A large amount of mackerel caught during the season is made into heshiko (pickled in rice-bran paste), and the heshiko is further processed into narezushi, which is used as an ingredient for special occasions such as the New Year.
Here in Wakasa Bay, Japan’s best sea fermentation technique has been passed down, and you can’t help but marvel at how much effort it takes.

When you think of the Sea of Japan, you think of rich and delicious seafood! However, if you visit Tagarasu during the cold season, you’ll see a scene like one in a daytime drama of an unpopular beach flooded with rough waves that go “bam!” and spread their lovely scenery.
The weather in the Sea of Japan in the Hokuriku region is unstable, and although Tagarasu is also rich in seafood, it seems that it was not possible to go fishing as much as I wanted.
The fact that the fishing season is short means that we have to efficiently process the fish that can be caught in a large amount in a short period of time into preserved food and survive the harsh winter. It is from here that mackerel heshiko technology developed.
By soaking the fish in salt and rice bran, it prevents contamination from bacteria and removes moisture to increase the shelf life.
Plus, the flavor is concentrated and delicious. This alone is wonderful, but in the Tagarasu village, it doesn’t stop at heshiko; it becomes narezushi!
I visited the manufacturing site at Minshuku Sasuke near the beach.
How to make heshiko-narezushi
Next, we start the narezushi process.
Heshiko is taken out, washed, stuffed with rice, and then marinated in a barrel filled with rice for several weeks to make narezushi. Mackerel heshiko can be seen throughout the Hokuriku region, but this is the first time I’ve seen heshiko-naresushi. I asked Mr. Morishita of Minshuku Sasuke, “Why do you do this when it’s so much work?” He told me, “It was a New Year’s offer to the gods.”
In this area, mackerel is a symbol of a bountiful catch. This episode shows that sushi was originally associated with Shinto rituals. Heshiko-narezushi takes more than a year if you count from pickling. It was a special food prepared for gods from the previous year.
Despite the fact that the raw fish is fermented for nearly a year and a half, there is no odor and a moderate amount of fat remains. When you take a bite, the soft taste of the mackerel, the concentrated richness of the heshiko, and the deep acidity of the narezushi triangulate perfectly to lock on to your taste buds.
It was so delicious that I fell to my knees!
