Japanese Vegetables

Cabbage is an inexpensive, versatile vegetable used to add nutrition and flavor to a broad range of meals. Cabbage is often sliced into thin strips to be served with korokke, tonkatsu (deep fried pork cutlet) or other fried dishes. It is also an important ingredient for okonomiyaki. Cabbage can be added to just about any dish, from soups and stews to pan-fried meals and salads. Japan is one of the world's top cabbage producers, and the vegetable itself is among the most popular at supermarkets.

Hakusai is popular in many parts of Asia, where it is often pickled. In Korea, hakusai is the cabbage variety usually used to make kimchi, the nation's most famous dish. In Japan, hakusai is also pickled in a dish known as hakusai no sokusekizuke, which, however, is much milder than kimchi. Furthermore, fresh hakusai is a very popular ingredient in hot pot dishes.

Horenso enjoys popularity thanks to its health benefits and variety of vitamins, being particularly rich in calcium and iron. A well known horenso dish is horenso no goma-ae (spinach with sesame dressing), which involves blanching the horenso and then mixing it with a sweet, soya sauce and sesame flavored dressing. Horenso is also used as a topping in soups.

Komatsuna is grown and consumed mostly in Japan, China, Taiwan and Korea. It is similar to spinach, in that it contains many important nutrients and vitamins, but it does not have the same bitterness as spinach. Komatsuna is commonly eaten raw in salads or boiled and served in soups and stews. It can also be pickled.

Mizuna has recently become very popular as a salad leaf. It is frequently paired with julienned daikon (giant white radish) in a fresh tasting salad. Otherwise, mizuna may appear in soups or Japanese hot pot (nabe), or as a garnish on various dishes.

Shiso is a mint-like herb whose distinctive flavor is a staple in Japanese cooking. It comes in two varieties. Aojiso (green shiso) is often served with sashimi, in salads or to flavor soups and stews. Akajiso (red shiso) is used to pickle Japanese plums and add color to dishes.

Daikon is a very popular and versatile vegetable. It can be eaten raw or cooked or grated into daikon-oroshi, a refreshing topping used to counteract the oiliness of dishes like grilled fish and tempura. Especially the bottom half is often quite spicy like other radishes. However, when cooked, this spiciness disappears and the vegetable becomes slightly sweet.

When used raw, daikon is usually cut into julienne strips and paired with mizuna leaves in a salad. When cooked, daikon is usually boiled in soups, stews or hot pot dishes. It is the most popular ingredient in the oden hot pot. Daikon also makes Japan's most popular pickle. Known as takuan, pickled daikon is included in virtually every dish of Japanese pickles. During the harvesting season, daikon hanging from farm houses in preparation for pickling is a common countryside sight.

Kabu is almost always boiled and served in soups or Japanese hot pot. It is a common miso soup ingredient and is often used to make pickles. Kabu usually have a spicier taste than Western varieties.

Jagaimo were not part of traditional Japanese cuisine until relatively recently. They are believed to have been brought by Dutch traders from Indonesia to Kyushu in the 17th century. However, potato cultivation in Japan did not begin until the end of the 19th century. Today, jagaimo are closely associated with Hokkaido where they are a regional specialty and common crop.

Jagaimo are popular in several Japanese dishes and adapted Western dishes. Nikujaga (meat and potato stew) combines beef, vegetables and potatoes in a sweet, soya sauce flavored stew. Jaga batta is a popular festival food in which a grilled potato is seasoned with butter and soya sauce. Jagaimo are also common in Japanese curry and korokke.

Satsumaimo were originally grown in Kagoshima, formerly called Satsuma. They are a popular winter vegetable used in both sweet and savory dishes. Satsumaimo are often simply grilled, peeled and eaten plain in a snack called yaki-imo. Satsumaimo may also be battered and deep fried in tempura or boiled in soups, stews or Japanese curry.

Daigakuimo is a dish composed of candied satsumaimo. Its name comes from the word for "university" because the snack was invented for university students looking for cheap, tasty food. Because of their natural sweetness, satsumaimo are also used to create sweets and snacks.

Satoimo are eaten throughout Asia, especially in India, China, Korea and Japan. They are a starchy root vegetable known for their somewhat sticky, slimy texture. Satoimo are always cooked before eaten, and typically appear in boiled or stewed dishes. Satoimo can be added to miso soup, Japanese hot pot, Japanese curry or appear battered and deep fried.

Nagaimo and its wild mountain variety yamaimo are slightly different in taste, texture and shape, but are prepared and consumed in the same way: sliced and grilled, or eaten raw. Raw nagaimo is grated to form a sticky, paste-like cream known as tororo. Tororo is used as a topping for rice, soba or udon noodles, or mixed with dashi (fish stock) for flavor. Some people experience a slight reaction when raw nagaimo comes in contact with their skin. This can result in a tingling sensation around the lips.

Common in Japan and greater Asia, renkon's attractive pattern makes it a useful vegetable for creating visually appealing dishes. It is not usually eaten raw, but peeled and boiled in water. Depending on how long it is cooked, lotus root may be crunchy like a fresh carrot, or starchy and soft, like a cooked potato. Renkon is often used in tempura, boiled in soups or stewed dishes like chikuzenni, fried in pan-cooked dishes or dressed with vinegar in a salad. It is almost always sliced to show off its attractive pattern.

Burdock plants exist all over the world, however, the vegetable is mostly consumed in Asia and especially in Japan. Gobo grow to 1-2 meters in length and are cut before sold to make them more manageable. Gobo are always cooked before eaten and are commonly added to soups as a topping. The most popular gobo dish is kinpira gobo, in which gobo and carrots are shred into thin strips, stir fried and glazed with soya sauce, sugar and sake.

Ninjin are a widely available and popular vegetable in Japan. They are often thicker than carrots seen in North American and European markets although the taste is the same. Like carrots in other parts of the world, ninjin are often enjoyed raw in salads, or cooked into various dishes such as Japanese curry and Japanese hot pot. Because of their bright color and sturdy consistency, ninjin are often cut into decorative shapes or simply used to add color and visual appeal to a dish.

Japan is one of the world's top onion producing countries, and onions are widely used in many Japanese dishes. As in most other cuisines, onions are usually cooked before eaten, and are a typical ingredient of many fried and stewed dishes such as Japanese curry, various domburi (a bowl of rice with some toppings) and hot pot. Onions may also be an ingredient in miso soup or grilled alongside meat in teppanyaki.

Ginger, originally imported from China, is commonly used in Japanese cuisine. It is a winter flavor, used to add heat to winter meals or served with fish to counter the "fishy" smell.

Grated ginger is sometimes served besides wasabi as a spice for certain types of sushi and sashimi and to add flavor or counter fishy aromas. Ground shoga is also often served on top of tofu for flavor. Thinly sliced, pickled ginger, called gari, is served with sushi and eaten in between pieces of sushi to clear the palate. Another kind of pickled ginger, beni shoga, is commonly served with heavy meats or fried foods such as yakisoba and tonkatsu. Beni shoga is a dark red pickle with a stronger taste than gari.

Takenoko symbolizes spring more than any other vegetable. As its name (lit. "child of bamboo") suggests, takenoko is the soft top of a young bamboo plant. Takenoko must be harvested just before the plant peaks out of the soil, otherwise it become hard and green. Takenoko is consumed grilled, steamed with rice, deep fried in tempura, or boiled in soups and stews.

Negi are included in many fried and boiled dishes, or used as a topping for domburi (rice bowl) dishes such as gyudon (marinated beef over rice). Negi are usually described as having a taste similar to the green onion, though sweeter. There are as many different varieties of negi as there are regions of Japan; however, the two most common are the Kanto variety with a long, white stem (see picture to the left) and the Kansai variety, whose stem is almost entirely green.

In Japan, tomatoes are mostly eaten in Western style cooking, eaten raw in salads or used as a garnish. While it is one of the most popular vegetables in Japan, it is rarely cooked in Japanese dishes. For their size and color, cherry tomatoes are especially popular in bento boxes.

Kyuri are usually thinner than Western cucumbers and are always eaten unpeeled. They are commonly found raw in salads or as a garnish, or pickled in an iced brine. Kyuri are a popular summer time vegetable.

Nasu are smaller and less bitter than their North American and European counterparts. They are an important vegetable in the Japanese cuisine and used in a wide variety of dishes.

"Nasu dengaku" is a dish in which the vegetable is cut in half and baked under a layer of miso paste. Another common nasu dish is "nasu miso itame" in which the vegetable is fried with onions, miso and sugar.

Nasu has also a place in cultural folklore: Dreaming about Mount Fuji, a hawk or nasu on New Year is considered good luck. And in a Japanese proverb, parents are warned against giving nasu to their daughters-in-law in the fall. This warning comes from the fact that fall nasu are particularly delicious and are better kept to oneself. However, it also refers to the fact that nasu are a "cooling" vegetable best eaten in the hot summer months. Consequently, it is thought to deter pregnancy, thus being a poor gift for a daughter-in-law.

Piman comes from the French word for pepper. Japanese piman are usually smaller than bell peppers. They have a thin skin and sweet taste, and are often served battered and deep fried as tempura, or stir fried in Chinese style dishes. They are also eaten raw in salads.

Shishito are a smaller variety of piman, Japanese green peppers. They are generally a sweet and mild pepper, although some varieties can be quite spicy. Shishito are most commonly served as tempura or roasted and topped with soya sauce and bonito flakes.

Kabocha make their appearance in fall and winter. Kabocha's high vitamin A content made it an important vegetable for northern Japan's long winters.

Kabocha is traditionally eaten in celebration of the winter solstice, the shortest day of the year, when people lack the nutrients found more commonly in summer vegetables. Kabocha is often enjoyed as tempura or boiled in sugar and soya sauce resulting in a soft, sweet dish. Recently, with the import of Halloween from North America, kabocha has become a popular ingredient around the October 31 holiday, for example in kabocha purin, sweet pumpkin pudding.

Foreign visitors to Japan may notice the frequent addition of corn to Japanese breads, pizzas, pasta, salads and more. Tomorokoshi is a popular vegetable in Japan, closely associated with Hokkaido. However, the vegetable is so popular that local growers cannot meet demand. Most tomorokoshi is now imported from the United States. Both fresh and canned corn is popular.

When tomorokoshi is in season, it is often grilled, buttered and seasoned with soya sauce. Tomorokoshi is also included in many Hokkaido specialty foods such as Hokkaido-style ramen (noodle soup) and miso soup.

Okura has a sticky layer surrounding the seeds of its fruit, producing a consistency similar to nagaimo (yam). When okura is consumed raw, the sticky texture is present, however, it is cooked off when boiled or fried. Okura is a summer vegetable that is often eaten raw in salads, deep fried in tempura, or served with soya sauce and katsuobushi (smoked bonito flakes). Okura leaves are not commonly consumed in Japan.

Goya is the most famous vegetables in Okinawan cuisine and the key ingredient in goya champuru, Okinawa's signature dish composed of stir fried goya, tofu and eggs. Goya is well known for its bitter taste.
