## History, Origin, and Related Events
During the mid-Edo period (around the mid-18th century) until the 1930s in the Meiji era, merchant ships sailing the western route along the Japan Sea from Hokkaido to Osaka were collectively referred to as "Kitamae-bune" (Northern-bound ships). These ships didn't just transport goods; they traveled from port to port, buying cheap products in one place and selling them at a higher price in another, generating substantial profits. Approximately 90% of the kelp (kombu) circulating within Japan is harvested in Hokkaido. Through the Kitamae-bune trade, kelp and other goods were transported to western Japan, significantly influencing the foundation of current Japanese cuisine.Fukui Prefecture has historical Kitamae-bune port towns such as Mikuni, Kono, and Tsuruga, where the flourishing trade brought in diverse culinary influences. Among the commodities transported from the north, herring (nishin) and kelp hold a special place. One of the preserved foods made from herring is "Nishin Sushi" or "Nishin-zushi." This sushi, pickled with herring, is prepared during the summer and consumed in autumn, maturing over 2 to 4 weeks. It is not only a delicacy during events like the Tsuruga Festival but also a celebratory dish served during the winter as part of Osechi, a traditional Japanese New Year's meal. The daikon radish absorbs the flavors of herring and koji (fermented rice malt) during the aging process, enhancing its deliciousness.

## Opportunities and Times of Eating Habits
"Nishin Sushi" is not limited to winter; it is enjoyed throughout the year using seasonal vegetables such as eggplant, cucumber, and gourd. The version prepared in summer becomes ready to eat during the busy autumn harvest. This practice represents a practical approach to obtaining nutrition without the need for elaborate cooking, showcasing the wisdom of daily life. Besides festivals, "Nishin Sushi" is also part of the New Year's celebration.

## How to Eat
Salted daikon radish and herring fillets, soaked overnight in water (using water from washing rice) to soften, are cleaned thoroughly before being cut and used. Daikon radish, carrots, and other ingredients are then marinated with koji and seasonings, allowing them to be preserved for approximately two weeks.
