Sakezushi, Kagoshima's rice-and-sake fermented sushi

Sakezushi (酒寿司) is a regional dish from Kagoshima Prefecture and a type of sushi. Rather than using the vinegar typically associated with sushi, sakezushi is built from rice seasoned with local jizake (a variety of haimotsuzake), layered with an assortment of mountain and sea ingredients, and—traditionally—given time for light fermentation to develop aroma and sweetness.

How sakezushi differs from other sushi

At first glance sakezushi can resemble pressed sushi (oshi-zushi), but its defining difference is liquid seasoning: rice is flavored with Kagoshima’s local jizake rather than the usual rice vinegar. Standard table vinegars common to most sushi are generally not used; the article notes that some modern recipes mix a little combined vinegar, but ordinarily no typical sushi vinegar appears in the preparation. Because multiple bottles of jizake are often incorporated, its aroma can be strong enough that people sensitive to alcohol may feel affected by the scent, yet the dish is reported to be enjoyed even by those who do not drink alcohol.

The local liquor behind the rice

The liquid called “jizake” or “jishu” in Kagoshima is not the same as general nihonshu. The local product used for sakezushi is a kind of haimotsuzake and is described as close to mirin in character. In present practice this jizake is used primarily as a cooking liquor—for sakezushi and for items such as satsuma-age—whereas until roughly the Meiji or Taisho eras it was often consumed at celebratory gatherings.

Typical ingredients and variations

Sakezushi assembles both mountain and sea produce. Common seafood examples listed include shrimp, sea bream (tai), red clam (akagai) and octopus. Vegetables and other local additions recorded in home recipes include fuki (butterbur), bamboo shoots, shiitake mushrooms, kinshi tamago (thinly sliced egg crepe) and satsuma-age (fried fish cake). Because the method is straightforward—season rice, layer ingredients, let the liquor work—sources note that practically any ingredient that suits sushi may be added, so recipes vary by household and occasion.

Traditional preparation — a household method

A typical home-style preparation described in historical recipes proceeds in clear steps:

• Make a seasoning by combining only the local jizake and salt; no other umami seasoners or typical sushi vinegar are used.
• Cook rice as usual and cool it.
• Mix three quarters of the seasoning into the cooled rice, then divide the rice into four equal portions.
• Lightly salt the inside of the sushi tub (sushioke) and lay down one quarter of the rice, flattening it.
• Scatter a selection of prepared fillings over the rice; fish are lightly salted and cut as for chirashi.
• Cover the fillings with the next quarter of rice and continue layering in the same way, using the remaining seasoning as the layers are formed.
• After the final rice layer, arrange remaining ingredients decoratively, lay haran leaves over the top and set the inner lid in place.
• Place a weight on the lid and adjust it so that the jizake inside the tub always reaches the upper step of the inner lid; adjusting this weight is pointed out as a crucial part of making good sakezushi.

When the weight is set, the finished product typically needs 4–5 hours resting to be ready. Longer resting allows enzymes in the jizake to lightly ferment the rice and ingredients, drawing out additional umami and sweetness. As a finishing touch, a few leaves of sansho (Japanese pepper) are sometimes placed on top for color. Among those who drink alcohol, some people sprinkle extra jizake over their portion when eating.

History and older records

Local tradition traces sakezushi’s origin to the Edo period. The story told in the source names Shimazu Yoshihiro, then the domain lord, as holding a hanami (flower-viewing) banquet; a maid placed leftover food and local sake together in a tub and left them, and the next morning a pleasant aroma was noted—this episode is described as the beginning of sakezushi. Documentary evidence appears in an early cookbook: the 1802 (Kyowa 2) publication Meihin Burui describes a dish called “Satsuma zushi,” in which mackerel (saba) is opened and rice mixed with sake is packed into its belly, then arranged in a tub while sprinkling sake (a sugata-zushi form); the same work notes that a kokerazushi form (rice mixed with ingredients or attached on top) was also made. Those records place sakezushi within the class of nama-nare sushi, where sake was used to promote fermentation; one historian cited in the source writes that in the past the sushi was pressed for seven to eight days. The prevailing view today presented in the source is that modern sakezushi remains as a survival of that nama-nare type of sushi, but most contemporary practice does not wait for extended fermentation.

Serving and social role

Sakezushi is described as a lavish, hospitality dish: its preparation is labor-intensive, and even now it is regarded as a representative food for entertaining. For that reason, sushi tubs used for sakezushi are often luxurious lacquered vessels. The combination of a decorative layered presentation and the distinctive aroma of the local jizake mark sakezushi as a dish made for special occasions and formal hospitality.
