Japanese Cuisine Soy-based Staple Food
Made from soy milk, tofu is a widely-consumed product in Japan. Nicknamed the "soy cheese", its taste is rather plain, with a faint smell and it often looks like a white rectangular block. It can be easily cooked with various seasonings to enhance its taste. Very affordable, it is also used as a staple in the preparation of many typical Japanese dishes.
Tofu is one of the basic foods of Japanese cuisine. Cheap and nutritious, it can be enjoyed in various forms and textures: in firm cubes, in little fried slices or as a thick cream or mixed with other ingredients such as vegetables, algae or meat.
For many travelers in Japan, natural tofu's taste and smell are thin. Actually, there is a wide range of Japanese tofu and the more you eat it, the more you get accustomed to it and can differentiate its aromas.
What is tofu?
When breaking down the Japanese words, its meaning is the following:
- 豆 (tô-) "bean";
- 腐 (-fu) "fermented".
Tofu could be described as a soy cheese, as its making process is quite similar to the cheese’s we eat in Western countries. Tofu making consists in the processing of soy milk, made from crushed soy beans. The most important step is to curdle the soy milk with a coagulating agent, called nigari in Japan, which is an extract of sea water naturally rich in magnesium chloride. Lastly, after removing the remaining liquid (similar to whey), the preparation is placed in a mold to obtain a white paste.
Tofu is therefore sold nature, in grocery shops or served at the restaurant as a rectangular or square shaped block, with various degrees of firmness.
Like the ramen 🍜 noodles, tofu was imported by Buddhist monks from China, where it was already consumed since a long time. Various hypotheses try to date its introduction in Japan:
- It was probably introduced thanks to the Buddhist monks in the 8th century;
- Some theories date the beginnings of tofu in Japan to the Heian period (794 - 1185) and more precisely at its end between 1183 and 1239;
- In 14th century’s texts, tofu is often mentioned, in a manner that proves it was already widespread at the times;
- Lastly, in the middle of the Edo period (1603 – 1868), tofu was a widespread food in the archipelago.
Buddhist temples have played an important role in the diffusion of tofu in Japan. A very nutritious food, especially rich in calcium, iron and vegetal proteins, it is a convenient substitute for meat and is therefore a perfect aliment for the monks’ traditional vegetarian cuisine called shôjin ryôri.
Industrial and artisanal making
Nowadays, tofu is produced in Japan by large factories making cheap industrial tofu, as well as by small and medium companies, and even artisans in a more traditional and quality-oriented range. However, the tofu-ya specialized shops have been declining over the last years and their number decreases due to the strong concurrence of supermarkets and their low prices.
On average, a 350g portion of tofu costs less than ¥100 (~US$0.76) in Japan. In 2004, the average yearly consumption by household amounted to ¥6,719 (~US$50.97), according to the Japan Tofu Association that represents the Japanese producers.
It is therefore easy to find tofu in supermarkets in Japan. The aisles are usually well-stocked, with prices on average from ¥36 (~US$0.27) to ¥175 (~US$1.33) the portion. You can choose based on the price, and for the best tofu do not hesitate to chose the most expensive, to get a tofu with a more pleasant texture and a more intense flavor. The date of consumption usually ranges from 2 to 12 days after purchase.
Otherwise, we recommend trying the small tofu artisanal shops that you can find in residential neighborhoods’ shopping streets in the cities. They are often managed by only one rather old shop owner, and sell their production in direct; it is a way of supporting local businesses. It also gives better chances to know where the soybeans come from and how they were produced (organic, sustainable, etc.)
How is tofu used in Japanese cuisine?
There are 2 main fresh tofu varieties:
- 絹豆腐 kinu tofu: a soft tofu with a creamy texture, almost like a pudding and often eaten cold.
- 木綿豆腐 momen tofu: a firm tofu with a denser consistence, easy to cook and used as an ingredient in various Japanese dishes.
Fried tofu, the favorite food of Inari shrines’ legendary kitsune fox, is also a staple, cooked as:
- 油揚げ aburaage, fine slices of fried tofu, dehydrated and ready to use, as a topping for a soup for example, and,
- 厚揚げ atsuage, a freshly fried tofu, sliced in large chunks or cubes.
Another way of eating tofu is to extract its skin, called ゆば yuba that forms at the surface of soy milk when it is boiled. It is also called tofu sheet and can be eaten fresh or tied in little knots for drying and to re-hydrate for consuming later.
In summer, an original specialty, the tofu ice cream, is offered by some artisanal ice cream makers or specialized shops in Japan.
Main tofu dishes
Tofu can be eaten nature, but to add it some flavor, it is at least seasoned with shoyu soy sauce. Then it is also the main aliment, source of proteins instead of / or in complement with meat, in many varied Japanese dishes, such as:
