Various Wasabi-Leaf Sushi from Around Japan

Various Wasabi-Leaf Sushi from Around Japan

Now let us take a concrete look at the wasabi-leaf sushi found in various regions.
We will explain in detail what features and appeal each one has.

Wakayama Prefecture (Hidaka District / Arida District)

In Wakayama Prefecture, the sushi known as wasabi-leaf sushi or wasabi-zushi is well known as a local specialty.

The sushi uses wasabi leaves nurtured by the clear waters of the Arida River, with fillings such as salted mackerel or fish simmered in a sweet soy glaze (kanroni).
Depending on the shop, some also use sweetfish (ayu) or salmon as fillings, and the variety seems to be wide-ranging from one household or region to another.
In the Hidaka District and Arida District of central Wakayama Prefecture, there is a custom of enjoying such wasabi-leaf sushi at events like Obon and autumn festivals.

In the Nanki-Shirahama area, there is also a sushi called "aoi-zushi" that uses sea bream (tai) as its filling.
In this aoi-zushi made with wasabi leaves, some families add the juice of natsumikan (summer orange) to the rice—a touch that feels very characteristic of Wakayama Prefecture.

It has the air of a sushi beloved by the people within the gentle climate and culture of Wakayama Prefecture.

Shizuoka Prefecture

Shizuoka Prefecture is famous as a producer of wasabi.

In Shizuoka Prefecture's wasabi-leaf sushi, the fillings are often Shizuoka-grown fish, beginning with vinegar-cured horse mackerel (aji).
Wasabi-leaf sushi made with Izu-grown wasabi leaves—Izu being renowned for the deliciousness of its wasabi—is especially characterized by a refreshing aroma.

You might call it a delicacy unique to Shizuoka Prefecture, with its abundant bounty of both the sea and the mountains.

Nara Prefecture

Among the sushi made with wasabi leaves, Nara Prefecture's wasabi-leaf sushi is also visually appealing.

Unlike the wasabi-leaf sushi of Wakayama and Shizuoka Prefectures, in Nara the distinctive feature is that the rice is wrapped in a wasabi leaf and then colorful ingredients are placed on top.
The toppings include salmon, eel (unagi), mackerel, shrimp, and more.

The charming bite-sized pieces, resembling temari-zushi (handball sushi), make it famous as a wasabi-leaf sushi popular among women.

The Taste of Wasabi-Leaf Sushi

From its name, wasabi-leaf sushi gives the impression that it might be very pungent.
But what does it actually taste like?

When combined with vinegared rice and fillings, the wasabi leaf has a sharp pungency, yet it lacks the impact of paste wasabi.
The wasabi's distinctive aroma provides a pleasant accent, making it very easy to eat with an elegant flavor.

The pungency of the wasabi leaf comes from a compound called allyl isothiocyanate.
This allyl isothiocyanate is known to have strong antibacterial and antifungal properties. (*1)
Because it works to prevent the growth of microorganisms, combining it with sushi also offers benefits in terms of hygiene.
