Local foods and products in Ibaraki Prefecture

Mito Nattô

Mito natto

Natto is one of the popular Japanese foods, and is made by fermenting the boiled soy beans.
(The last "o" in "natto" is pronounced long.)

It is rich in nutrients and is a healthy food, but it has a distinctive smell.
So most foreigners probably don't like it.

Originally natto had been made locally as a home industry.
But in early 20th century, a natto maker in Mito began to mass-produce natto industrially.

Since that, most Japanese people associate "natto" with "Mito".


Anko and Anko-nabe
Ankô & Ankô-nabe

"Ankô" is one of deep-sea fish, and it is called "anglerfish" or "goosefish" in English.
Many anko are caught off the east coast of Ibaraki Prefecture.

Anko has a grotesque body, but it tastes good.

Not only its meat but also inner parts, skins, gills and fins are eaten.
Especially the liver is similar to "foie gras" because anko is a tremendous eater in the sea.
So it is much-prized.

Anko-nabe is one pot stew with all parts of anko, vegetables and tofu.
The soup are mixed with either shoyu (soy sauce) or miso.

In winter, we can eat it at any ryokans or restaurants at the northeast coast in Ibaraki Prefecture.



Melon is one of popular fruits in Japan.

It is expensive, so it is often used as a gift in Japan.
As a result, many Japanese people can sometimes eat melon.

Ibaraki Prefecture is the top producer of melon in Japan.
Especially, Hokota city at the southeast part of the prefecture is the center of the production.

Some varieties of melon are cultivated in Ibaraki Prefecture and every melon has its unique characteristics.
