Japanese Vegetables 1~6


Burdock root, greater burdock or edible burdock root is called “gobou/牛蒡” in Japanese.
Its Latin name is Arctium lappa.

Although it is a root vegetable with great nutritious and even medical properties, it is commonly eaten only in Japan and Taiwan.

This species is native to the temperate regions of the old world, from Scandinavia to the Mediterranean, and from the British Isles through Russia, and the Middle East to China and Japan, including India.

It is naturalized almost everywhere and is usually found in disturbed areas, especially in soil rich in nitrogen. It is commonly cultivated in Japan.

It prefers a fresh, worked soil, rich in humus, and should be positioned in full sunlight. Burdock is very reactive to nitrogen fertilizer. Propagation is achieved through sowing the seeds midsummer. The harvest occurs three to four months after the seeding until late autumn, when the roots become too fibrous.
In shizuoka it is more and more cultivated in organic fashion with natural/organic fertilizer and no pesticides.

Greater burdock was used during the Middle Ages as a vegetable, but now it is rarely used, with the exception of Japan where it is called gobō (牛蒡 or ゴボウ), Taiwan (牛蒡), Korea where it is called ueong (우엉), Italy, Brazil and Portugal, where it is known as bardana. Plants are cultivated for their slender roots, which can grow about 1 meter long and 2 cm across.

Immature flower stalks may also be harvested in late spring, before flowers appear. The taste resembles that of artichoke, to which the burdock is related.

The root is very crisp and has a sweet, mild, and pungent flavor with a little muddy harshness that can be reduced by soaking julienned/shredded roots in water for five to ten minutes. The harshness shows excellent harmonization with pork in miso soup (tonjiru) and takikomi gohan (a Japanese-style pilaf).

A popular Japanese dish is kinpira gobō, julienned or shredded burdock root and carrot, braised with soy sauce, sugar, mirin and/or sake, and sesame oil. Another is burdock makizushi (rolled sushi filled with pickled burdock root; the burdock root is often artificially colored orange to resemble a carrot). In Kyoto, gobō can also be found as a snack food similar to potato chips. The root is eaten cooked and the young sprout can be eaten just like asparagus. Gobo is also used in tempura.

Apart of its obvious culinary value, it is also valuable for its high content in dietary fibers and beneficiary nutrients.
It has been utilized as a medicinal plant with diuretic, diaphoretic, and blood purifying capabilities. The Japanese have also recognized it to prevent cancer and combat diabetes.

Lotus roots come from a plant called Nelumbo nucifera, also known by a number of names including Indian lotus, sacred lotus, bean of India, or simply lotus. This plant is an aquatic perennial. Under favorable circumstances its seeds may remain viable for many years.
A common misconception is referring to the lotus as a water-lily (Nymphaea), an entirely different plant.

Native to Greater India and commonly cultivated in water gardens, the lotus is the national flower of India and Vietnam.

The flowers, seeds, young leaves, and “roots” (rhizomes) are all edible. In Asia, the petals are used sometimes for garnish, while the large leaves are used as a wrap for food. In Korea, the leaves and petals are used as a tisane. Yeonkkotcha (연꽃차) is made with dried petals of white lotus and yeonipcha (연잎차) is made with the leaves. The rhizome (called ǒu (藕) in pinyin Chinese, ngau in Cantonese, bhe in Hindi, renkon (レンコン, 蓮根 in Japanese), yeongeun (연근) in Korean is used as a vegetable in soups, deep-fried, stir-fried and braised dishes. Petals, leaves, and rhizome can also all be eaten raw, but there is a risk of parasite transmission (e.g., Fasciolopsis buski): it is therefore recommended that they be cooked before eating.

The stamens can be dried and made into a fragrant herbal tea called liánhuā cha (蓮花茶) in Chinese, or (particularly in Vietnam) used to impart a scent to tea leaves. The lotus seeds or nuts (called liánzĭ, 蓮子; or xian liánzĭ, 鲜莲子, in Chinese) are quite versatile, and can be eaten raw or dried and popped like popcorn, phool makhana. They can also be boiled until soft and made into a paste, or boiled with dried longans and rock sugar to make a tong sui (sweet soup). Combined with sugar, lotus seed paste becomes one of the most common ingredient used in pastries such as mooncakes, daifuku, and rice flour pudding.

“Fruit Tomatoes”

This summer-maturing fruit can be bought all year round with the interesting consequence that tomatoes ripened in winter are sweeter than their summer cousins as they contain less water, earning themselves the name of “fruit tomatoes”, a great oxymoron, if there was one!

Thanks to consumers’ insatiable appetite for novelty, tomatoes are grown into all kinds of size, shape and colour.
Just to cite a few, the following are the most popular in Japan:


“Momotaro Tomatoes”

Recently a yellow version is being grown experimentally.

Ssweet potatoes should not be confused with yams or yama imo/山芋 in Japanese.

They have been recognized in this country for a long time for both their nutritional and pharmaceutical values.

Asparagus has been used from very early times as a vegetable and medicine, owing to its delicate flavour and diuretic properties. There is a recipe for cooking asparagus in the oldest surviving book of recipes, Apicius’s third century AD De re coquinaria, Book III. It is said that it was cultivated by the ancient Egyptians, Greeks and Romans, who ate it fresh when in season and dried the vegetable for use in winter. It lost its popularity in the Middle Ages but returned to favour in the seventeenth century.

It is recognized in many quarters as natural medicine:
-Asparagus rhizomes and root are used ethnomedically to treat urinary tract infections, as well as kidney and bladder stones.
-Asparagus is also believed to have aphrodisiac properties (this belief is at least partially due to the phallic shape of the shoots).


-Season (in Japan): May~June
They are at their best March~June in the Northern Hemisphere, but can be obtained all year round thanks to state-of-the-art greenhouse cultivation.

Asparaguses are abundant in the wild, but they grow very quickly and get too hard for consumption.
The wild ones picked in their natural environment are my favourite as I fondly remember picking them up as a soldier in the South of France during our drills and cooking them in simple omelettes!


Violet asparaguse are very popular in any restaurants!


Mini-asparaguses are ever so popular in Japan thanks to their practical size.


-Choose asparaguses with a clean cutting surface. No black spots should appear.

-The darker the colour, the better. As for white asparaguses, choses with a “wet cutting”

-When storing your asparaguses in the fridge, have them stand upright in a long narrow container with their foot wrapped in wet kitchen paper. Discard bent asparaguses on the supermarket stands.

-Choose green asparaguses with the smallest possible foliage along the stems and dark tips.

-When boiling them, either boil them stading upright inside a pasta mesh container, or absolutely flat in a sauce pan. Do not bend them.

-Asparaguses are best digested when lightly fried with oil.

-If Asparaguses cannot be obtained directly from the farmer, lightly peel but keep yop half as it is to preserve Vitamins.



Recipes are endless, but my favourite is the large green asparaguses and mozzarella gratin as prepared and served at Uzu/うず Izakaya in Shizuoka City!



Leeks, or “negi/葱” in Japanese, are an almost universal vegetable.
It is used in cuisine at restaurants and homes on all continents and have been recognized for ages as very beneficial plant.

Some people do not appreciate them because of their pungent smell and taste, but this can be taken care of with a couple of simple steps.

Back home in France, we boil the central part of fat leeks and eat them under the name of “poor man’s asparaguses”!

-Season: leeks can be bought all year round, but the best season is from November to February in the Northern Hemisphere.
