Shirasu (しらす)

    Do you know what shirasu is? Dry goods stores heap “dried shirasu” in their storefronts. This fish, rich in protein, vitamin D, calcium, and magnesium, can be eaten with bones. The name may differ depending on the region, but in order of the highest moisture content, it goes by kamaage shirasu, dried shiras, or semi-dried young sardines. Fish called Shirouo and Shirauo may have similar names and appearances, but they are completely different species from these three.

    The popular whitebait of Japan

    In Japan, whitebait is called shirasu, which is small immature fish. They are less than 2cm in length, typically sardines, but can also be the fry of herring, sweet fish, conger eel, or others. This tiny fish ingredient can be found in almost all Japanese supermarkets. You can eat it raw or boiled. If dried after being boiled then the shirasu turns into chirimen. There are many names depending on how long their dried or the region. Speaking of regions, this ingredient is popular and famous in the Kanagawa prefecture.

    raw shirasu and shirasu don

    Kanagawa and the Shirasu season

    During the shirasu season of spring and fall you will see plenty of advertising for raw shirasu at shops in the Kanagawa prefecture. It can be caught at any time, but it is most delicious in those seasons. They do a great job of fishing it in Sagami Bay. A specialty in Kanagawa is the shirasu-don, which is the shirasu on top of rice. The shirasu rice bowl is a must try for people in that region. They also have the shirasu tsukimi-don, meaning moon-viewing shirasu rice bowl. It has a raw egg yolk in the center which represents the moon.

    Health Benefits of Shirasu

    Shirasu is easy to prepare, as you do not cut anything out. Eating the whole thing means you get all the nutrients it has to give. The nutrients it does give are: calcium for the bones, taurine and potassium for your liver, and other vitamins and minerals, especially vitamin D. What makes it really healthy is the rich levels of DHA (docosahexaenoic acid). This improves the cell membranes to effectively boost one’s learning ability. Eating it every day would really help make your bones stronger, body healthier, and brain better.

    raw shirasu and boiled shirasu in boxes

    On the left side, we have the raw shirasu and on the right side we have the boiled one. Only the largest and least fragile of the delicate baby fish are kept to be served raw, while the others are lightly boiled in salted water. They then spread the boiled ones out on screens to dry them outside in the sun. When consumed in its raw state, it will possess a chewy texture and emit a distinct aroma reminiscent of the ocean. However, when boiled, it undergoes a transformation, becoming fluffier and acquiring a saltier taste. Furthermore, when dried and processed into chirimen, it takes on a jerky-like consistency and delivers a delightful savory flavor. There are another fish food we do recommend is namerou.

    Season of whitebait

    There are two seasons when whitebait is at its best: spring and fall. Spring is from late March to May, and fall is from mid-September to November. However, there is a fishing ban in Shizuoka Prefecture from January 15 to March 20, so you cannot eat it in the spring in that area.


    What kind of fish is shirasu?

    “Shirasu” is a general term for sardine, eel, and ayu (sweetfish) fry, but Japanese anchovy fry are generally called shirasu.

    What is the difference between Whitefish and Shirasu?

    The frogfish reaches a length of approximately 3 cm and starts to acquire a silver hue that resembles adult sardines, earning the name “kaeli”. Eventually, the frogfish grows to around 5 cm in size and people refer to it as a sardine.

    Where to eat shirasu?

    Raw shirasu are hard to come by because they spoil quickly. Only shops that can get them delivered quickly serve them. This means you will almost never see it in a major city like Tokyo. They need to be closer to the water and the fishermen who catch them. People must eat the raw shirasu caught on the same day. Kanagawa prefecture is the ideal place for this. Even though people typically eat whitebait over rice, Japanese cooks have invented many creative variations. No matter how you try it, it offers a wonderful and traditional Japanese experience.
