Japan for the Uninvited

Japanese culture from a bemused foreign perspective

Funazushi (Fermented raw fish)

FunazushiIn most countries, rotten fish is thrown out. In Japan, they spend 3 or 4 years making it, and consider it an expensive luxury. Funazushi, the speciality of Shiga prefecture, is fermented buna (crucian carp).

The raw fish is packed tightly in salt for a year, then dried and mixed with rice. This mixture is left to “ferment” for 3 years. The rice is changed every year, but the fish is allowed to decompose.

As you’d expect, funazushi has an overpowering smell, which discourages many people from trying it. The taste is sharp and vinegary. It can be used in soups, deep-fried in batter to make tempura, or served in green tea (ochazuke).

History of funazushi

Around 1000 years old, a preservation method called narezushi came to Japan from China. In Shiga, narezushi became funazushi. Fermentation was used as a way to preserve food stocks for the winter. Like many other Japanese foods (umeboshi, natto), funazushi became a national delicacy, even when fresh food became available all year round.

Funazushi is increasingly rare. As fresh fish has become available, modern sushi has been developed, reducing funazushi to novelty status. Younger Japanese people, who have more Western tastes, are less likely to develop a taste for the dubious treat. Recently, it can only be found in Shiga, and the smelly preservation technique may soon be redundant.

    I lived in Japan back in the 1960’s while serving with the US Air Force. I regret never having tried funazushi. I am a lover of stinky cheeses, the stinkier the better, and am sure I
    would enjoy funazushi also. Strong smelling foods usually have robust flavors and that is what I like.

    I just tried funazushi today and came across this article looking for more information. I have to say – it would really, really be a shame if “the smelly preservation technique” became redundant. Funazushi is amazingly delicious – somewhere between prosciutto and stinky-delicious cheese, with a tiny bit of fishiness thrown in for good measure.

    However, I have to admit that only one of the 10-12 japanese people present today was willing to eat, let alone like, the dish – so perhaps there isn’t such a huge market for it.

    In summary, if you like fish, prosciutto (生ハム) and blue cheese, you should really try this dish.

    Sounds to me like Spanish bacalao (salt cod).

    We also have a similar dish called, Burong Isda, which literally means Fermented Fish. It’s one of my favourite Filipino dish from the north. My grandfather used to catch fresh water fish then, after cleaning, my grandmother would mix cold pre-cooked rice and loads of salt. It’s fermented for a week or two and then sauted with lots of onions, garlic, ginger and tomatoes.. It is a great accompaniment for boiled veggies. Sadly, my grandmother died and the exact recipe was not handed down..

  6. I had the pleasure of having it when I lived in Minamihama, on the shores of Biwako. I was living with a host family there, and a couple of times they had it while drinking beer. They prepare it themselves. They called in “Japanese cheese” and where really very, very pleased that I was able to eat it with them. I have to admit that I wouldn’t agree with Joe that it is “amazingly delicious” and it in no way reminded me of prosciutto. It reminds me of some of the fermented dishes I have eaten elsewhere, though, like in Cambodia and Vietnam.

    Yes I was curious about this also. Too bad Karl just isn’t open minded enough to enjoy something like that. I admit I would have to put down a few beers to get the courage up.

    Came here because of Karl too! Love that show! I’d love to try this if I ever had the chance.

  20. WAT

    The fish doesn’t become ‘rotten’ it is fermented, there is a difference.. The fermentation keeps the fish from becoming rotten due to the drop in ph.
