Moriguchi zuke Moriguchi daikon pickled in sake and mirin kasu

Moriguchi zuke (守口漬) is a preserved vegetable made by salting Moriguchi daikon, repeatedly curing it in sake lees (sake kasu) and finishing the product with mirin lees (mirin kasu). The method was devised in Nagoya in the early Meiji period by entrepreneur Yamada Saikichi and sold from his store; over the following decades the product became a named specialty associated with producers and makers in Aichi and Gifu prefectures.

Main producers and shops

The modern market for Moriguchi zuke grew around a small group of long-standing Nagoya makers. The shop where the product was first sold—operating under the name Kitafuku—became the best-known outlet. Kitafuku traces back to Yamada Saikichi’s store opened in 1881 near Wakamiya Shrine in Nagoya’s Naka ward; the business later continued under the Kitafuku Sohonke name and remained a recognized maker until corporate closure in 2021, after which a previously spun-off Tokyo business using the Kitafuku trade name took over the屋号 and trade.

Other principal makers named in historical accounts include Yamatoya Moriguchi-zuke Sohonke, which expanded its presence with advertising and early moves into Nagoya subterranean retail; Kotobukitawaraya, established in 1980 by a former Yamatoya head clerk who moved production into Fuso Town and adopted a different, more mass-market approach; Akisetsu Pickles, a firm with roots in an early Okazaki–Nagoya shop; and Owariya, whose origins trace to a small processing operation handling market vegetables before adding Moriguchi zuke production in the early Shōwa period. These makers have been central both to product continuity in Nagoya and to the industry organization that coordinates supply with farmers in Aichi and Gifu.

Origin and early history

Yamada Saikichi opened a food and pickles shop called Kitafuku in 1881. He brought slender daikon from his native Gifu, developed a method of first salting the radish, then curing it repeatedly in sake kasu and finally finishing it with mirin kasu; in 1882 he sold this product as “Moriguchi daikon mirin-kasu zuke.” At a time when mirin was a relatively novel sweetener, combining the traditional use of sake kasu with mirin kasu drew attention and helped the shop prosper. Yamada also sold a mirin-kasu–cured cucumber using the same approach.

When Sasajima Station (later part of Nagoya Station) opened in 1887, Yamada negotiated to sell the pickles at the station as a Nagoya souvenir; from the Meiji era onward he frequently exhibited the product at trade exhibitions and fairs, and the pickles became identified among Nagoya’s local products in contemporary industrial histories.

How Moriguchi zuke is made

The full method unfolds across more than two years. Harvested in autumn, Moriguchi daikon are salted immediately so their moisture is drawn out. After dehydration the first key transfer (shimotsuke) is made, typically around the following February: the roots are repacked in salt or in a salt mixture that includes sake kasu. From about May through the next February producers carry out the main seasoning (ajitsuke), repeatedly immersing the radishes in sake kasu over five to six rounds. This repeated curing both leaches salt and softens the daikon’s firm fibers; the greater the number of soakings, the milder the final taste. After the main pickling, a final finishing step (shiage-zuke) uses sake kasu blended with mirin kasu to adjust sweetness and round the flavor.

Because the character of sake kasu varies by brewery and by production timing, makers adjust the kasu formulations and curing regime across the year to keep quality consistent.

Taste, serving and culinary uses

Moriguchi zuke is typically sold in packets of cured roots. Standard serving practice is to take from the packet only the amount to be eaten, wipe off or briefly rinse away the adhering kasu, and slice the daikon to the desired shape. It appears in simple preparations such as ochazuke and alongside fish cured in sake lees. As with Nara-style kasu pickles, pairing Moriguchi zuke with grilled eel (unagi no kabayaki) is a classic combination: the pickles help clear the fatty aftertaste left by the eel. Contemporary accounts attribute this effect to melanoidins in the kasu, stating that these brown compounds stimulate gastric function, reduce heartburn, assist fat breakdown and aid absorption of vitamins and minerals.

Moriguchi daikon cultivation and regional shifts

Historically the slender radish used for Moriguchi zuke was grown along the Nagara River area of Mino Province (now parts of Gifu). Before the war, villages such as Noritake and Shima in Gifu were principal production sites. Wartime shortages of land, seed and kasu halted much cultivation and made kasu and sugar difficult to obtain, leaving only small-scale sales.

After the 1950 National Athletic Meet held in Aichi prefecture produced a surge in demand, Nagoya makers and farmers pressed to re-establish station sales; as sellers regained market presence in Nagoya, production areas shifted. In 1951 producers in Fuso Town, Aichi, obtained seed stock from Gifu and began cultivation; the following year Fuso growers formed a production cooperative. From active local support and subsidy programs in Aichi, planting grew and by the 1970s the balance of acreage and output had moved: since 1971 Aichi (Fuso Town in particular) has held the top position nationwide for area planted and output of Moriguchi daikon.

Industry organisation, names and related products

To coordinate supply and standards, Nagoya makers formed an industry association in 1952 called Meijo-kai; in 1984 it became the Nagoya Moriguchi-zuke Norenkai. The Norenkai comprises a set of member firms (twelve companies are listed in later records) and maintains contractual arrangements with the joint producer body for Aichi and Gifu that set annual production volumes and pricing.

Regional name overlap and variant traditions exist. In Osaka and the Kawachi area a separate “Moriguchi zuke” tradition survived as a local kasu-pickled vegetable product; local tradition in Kawachi even attributes the name to a presentation once made to Toyotomi Hideyoshi when he rested in Moriguchi village. An 1836 pickling manual describes a Kawachi-style preparation that differs materially from Yamada’s mirin-kasu method: the older approach steamed or blanched daikon, dried briefly, then packed in a soupy kasu with salt and pressed. The radish varieties behind these two paths are not identical either: Osaka’s historical “Moriguchi” roots trace to market-grown Miyamae daikon around Tenmangu in that city and largely disappeared as the area urbanized; the Moriguchi daikon used for the Nagoya-style kasu pickles derives from slender Mino-region roots long used for drying, later developed into the cultivar now called Moriguchi daikon.

Kōnan-zuke is a named product manufactured outside Nagoya that follows the kasu-curing approach: a Kobe firm produces a kasu pickle using sake lees from Nada, mainly employing Moriguchi daikon from the Gifu–Aichi river valley, and also produces mirin-kasu pickles from Tokushima cucumber and small watermelons from Wakayama and Awaji Island.
