Narezushi pressing tub
なれずし桶・重石
A narezushi pressing tub is a wooden bucket or barrel for packing salted fish and rice under a cover and weight. Regional methods vary; some also water-seal the tub.
A weighted wooden tub
A narezushi pressing tub is a broad wooden bucket or barrel that holds fish and rice during packing and fermentation. Regional food records describe the same working principle in different words: Wakayama's recipe packs wrapped fish firmly in a wooden bucket and puts a weight on top; Mie's recipes use a pickling barrel with a cover and weight. A photograph from a Shiga funazushi storeroom shows traditional wooden tubs beside substantial stone weights. Together these sources document a traditional wooden form and its load, while leaving dimensions, wood species and construction details unspecified.
The tub is not simply a serving container. It confines layers of fish and rice, and the cover and weight keep them pressed into place. Some methods use a wooden cover; the Shiga cultural-property record also describes a bamboo-sheath cover. It does not follow that every tub has the same follower shape or that a single stone size is standard.
Packing and pressing in Wakayama
The Ministry of Agriculture, Forestry and Fisheries describes a Wakayama narezushi made with salted mackerel, rice and leaves. Once the fish and rice are prepared and wrapped, the bundles are packed tightly into a wooden bucket and weighted. That arrangement holds the compact layers together while they pickle. The record identifies the Arita region as a main lore area and gives local choices of wrapping leaves and fish; it also cautions that recipes vary between households and regions.
This bucket belongs to a fermentation process, not to quick vinegared sushi. The regional account describes salted fish and rice fermenting together, with the wrapped bundles packed in the tub under load. It does not specify a universal tub capacity or say that every Wakayama maker uses identical materials.

Mie methods: barrel, cover and water seal
Mie's regional account describes narezushi across the prefecture, where fish and rice treatments differ from place to place. In its eastern Kishu example, fish and rice are layered in a pickling barrel, covered, weighted and water-sealed. The cover and weight help keep the packed contents below the surface; the water seal is a separate part of that method, not an inherent feature of every wooden tub.
The same source describes a later pressing step: after pickling, the barrel is inverted and weighted overnight to press out excess moisture before the narezushi is removed. This makes the equipment's role clear across stages. The vessel contains the packed ferment, while its weight maintains pressure and can also be used during the regional draining step. The record does not publish a required load or barrel dimensions.

A related Shiga example
The Agency for Cultural Affairs records Omi narezushi making in Shiga as an intangible folk technique. In its funa-zushi process, salted fish are arranged in a tub with cooked rice, covered, and weighted to press the contents; water may be added around the tub to exclude air. A 2009 Tokyo Foundation account also documents wooden tubs used by a Shiga maker and notes that the producers keep their containers clean.
These Shiga records help show a traditional weighted-tub form, but they describe a related local practice rather than a template for Wakayama or Mie. Across the sources, the common element is a tub that holds tightly packed fish and rice under a cover and load. Specific fish, leaf or rice arrangements, water seals, timing and pressing sequence remain local choices.

What the sources do not standardize
The records do not state a standard length, width, capacity, wood species or stone mass. They also do not establish a single shape for the lid or follower. A photograph can document actual wooden tubs and stones, but it cannot supply measurements for every maker's equipment. Those details should be treated as specimen-specific unless a maker or technical source provides them.
The inspected sources document present or recent regional practice, not the first invention of the tub, a universal cleaning regimen, or a retail source for one. The Tokyo Foundation article reports that one producer family takes care to keep its containers clean; it does not set out a general maintenance procedure. The safe description is therefore functional and regional: a wooden tub, a cover and a weight, used in varying narezushi methods.
History
Government regional-cuisine records describe the weighted bucket or barrel in Wakayama and Mie. A 2009 Tokyo Foundation account documents traditional wooden tubs in Shiga. These sources attest use and form, not the date or place of invention.
Equipment details
CapacityThe inspected sources give no standard capacity for these regionally varied tubs.
SizeNo inspected source supplies standard diameter, height, or follower-weight dimensions; the illustrated and described forms should not be treated as a universal specification.
PowerNo power The tub and passive weight work without a powered mechanism; the sources describe manual packing and pressing.
How you get oneNot established The sources document wooden tubs in traditional practice but do not identify a present-day maker, purchase route, or standardized retail product.
CareThe Tokyo Foundation account says producers take care to keep containers clean but does not provide a general cleaning or drying protocol.
Made of
- Wood — Tub body
Wakayama's regional recipe specifies a wooden bucket; the Mie and Shiga records refer to a pickling barrel or tub. They do not specify wood species or construction details. - Wood or plant-fibre cover — Cover / follower
Regional records describe wooden covers or a bamboo-sheath covering. A fitted disk shape is not specified for every method. - Stone — Pressing weight
The Japanese cultural-property record describes a weight placed on the covered tub; the Tokyo Foundation photograph shows stones on traditional wooden tubs. Individual stones are not dimensioned.
Limits
The weight is part of packing and pressing the fish-and-rice layers; it is not a cooking lid or a universal seal. Mie and Shiga records describe additional regional covers and water-sealing practices.
Source →Tub materials, covers, fish, rice preparation and pressing sequence vary by regional recipe. The sources do not establish a single design, capacity or weight for all narezushi.
