What is Japanese Tofu: In-Depth Guide to a Culinary Staple

What is Japanese Tofu

Japanese tofu, an essential ingredient in Japanese cuisine, is made from coagulated soy milk, resulting in a soft, custard-like texture. Often referred to as silken tofu, this tofu variety differs from others as it is not pressed to extract the whey. Instead, the soy milk solidifies into a smooth and soft block that is delicate and versatile in multiple dishes¹.

Tofu is considered a “superfood” in Japan because it contains a high amount of nutrients in a compact package. One of its distinctive features is that it’s a complete protein, providing all nine essential amino acids the body needs². Furthermore, a 3-ounce serving of tofu can offer a sufficient portion of lean protein, ensuring long-lasting satiety.

There are several types of Japanese tofu available, each with its unique texture and use. Some of the most common varieties are:

• Silken Tofu (Kinugoshi-dofu): Soft, smooth, and custard-like, often used in soups, smoothies, desserts, and savory dishes¹.
• Regular Tofu (Momen-dofu): Pressed and spongy, it comes in various densities from medium to extra firm, suitable for a wide range of recipes, including miso soup, cold tofu, and mapo tofu³.

Besides these common types, Japan also features regional tofu varieties, such as fermented tofu (tofuyo), an Okinawan dish. Tofuyo is made from fermented tofu soaked in malted rice and awamori liquor, resulting in a powerful and pungent flavor often compared to strong cheese⁴. This tofu is typically served in small portions with alcoholic beverages at Okinawan restaurants.

Japanese tofu is ideal for incorporating into a diverse array of dishes. It’s commonly used in traditional Japanese recipes like miso soup, cold tofu, and mapo tofu, but it can also be incorporated into smoothies, desserts, puddings, salad dressings, sauces, and dips³.

In comparison, Chinese tofu is more firm and dryer, making it better suited for meaty vegetarian dishes. While Chinese tofu is less moisture-concentrated and easier to cook with, Japanese tofu often requires special care and attention during the cooking process, given its softer and more delicate nature⁵.

Japanese tofu showcases the unique characteristics and versatility that make it a must-try element in Japanese cuisine, offering plenty of health benefits and a wide range of culinary applications.

Types of Japanese Tofu

Soft Tofu

Soft tofu, also known as kinugoshi-dōfu in Japanese, is a type of tofu with a silky smooth texture. It is made by coagulating soy milk and retaining most of its water content, which gives it a delicate and fragile consistency. This tofu is not pressed and typically comes in block forms. It is often used in dishes like miso soup, cold hiya-yakko, and warm dishes where its texture can be appreciated without losing its form [1].

Silken Tofu

Silken tofu, or kinu, is a Japanese tofu variant with an even smoother and silkier consistency than soft tofu. Its name originates from the form “kinu”, which means “silk” in English. Like soft tofu, silken tofu is not pressed and has high water content [2]. It is versatile and can come in a range of textures from soft to firm, often used in dishes like hiya-yakko or in soups, sauces, and desserts that incorporate its creamy and silky texture.

Firm Tofu

Firm tofu, or momen-dofu, is made by pressing more water out of the tofu curds than soft or silken varieties. This results in a denser texture that holds its shape better when cooked. Momen-dofu is ideal for use in stir-fries, baked dishes, and other cooking techniques where maintaining its form is crucial. It has a firm, springy texture and absorbs flavors well, making it a popular choice in many Japanese recipes [3].

Cotton Tofu

Cotton tofu refers to the firm, less-silky alternative to the silken tofu found in Japanese cuisine. This type of tofu is characterized by a spongier texture and is often used interchangeably with firm tofu due to their shared qualities. It can be found in a variety of dishes, including hot pots, skewers, and stews, where it maintains its consistency and absorbs more flavor from the surrounding ingredients.

Frozen Tofu

Koyadofu, or frozen tofu, is made by freezing tofu and then thawing and pressing it to remove excess water. This process alters the tofu’s texture to be more porous, spongy, and able to absorb flavors more effectively than non-frozen varieties. In Japanese cuisine, koyadofu is often used in dishes like nimono (simmered dishes) and miso soup, where it soaks up the flavors of the broth [4].

Fermented Tofu

Tofuyo is a type of fermented tofu originating from Okinawan cuisine. It is made by fermenting tofu, sometimes with added ingredients such as koji mold or red yeast, creating a strong, distinctive flavor and pungent odor. Fermented tofu is eaten in small quantities as a condiment or appetizer due to its intense taste [5].

Production Process

Soy Milk

The production process of Japanese tofu begins with soy milk, which is created by soaking dried soybeans in water and then crushing and boiling them. This process helps to extract the soluble proteins and oils, while leaving the insoluble fibrous materials behind. Soy milk is a key component in tofu production, as it serves as the foundation for creating the soft, delicate blocks of bean curd that we know as tofu¹.

Coagulation

Coagulation is the next critical step in tofu production. During this phase, a coagulant is added to the soy milk, causing the proteins and oils to coagulate into curds. Various coagulants can be used to produce different types of tofu, though the most common are salts, acids, and enzymes².

In the case of Japanese tofu, the most widely used coagulant is nigari, or magnesium chloride³. Nigari has a unique ability to create a smooth, silky texture in tofu that is particularly prized in Japanese cuisine. Another popular coagulant is gypsum, or calcium sulfate⁴. This mineral helps to produce a firmer and more substantial block of tofu, suitable for dishes that require a more robust texture.

Pressing

After the coagulation step, the resulting curds and whey must now be separated. The mixture is typically poured over a cheesecloth-lined mold and the cloth is folded over the curds to secure them inside. The mold allows the whey to drain away, leaving behind only the solid curds⁵.

The curds are then pressed to form tofu. The amount of pressure applied during this step determines the final texture of the tofu, with more pressure resulting in firmer blocks. In Japanese cuisine, various types of tofu are used, ranging from the soft, custard-like silken tofu to the dense, hearty blocks of firm tofu⁶. To make these different textures possible, the tofu maker must carefully control the pressing process by adjusting the weight and time used for this step.

Nutritional Value and Health Benefits

Japanese tofu, also known as bean curd, is made from soybean curds which originate from Japan. This plant-based food offers a myriad of health benefits thanks to its impressive nutritional profile.

One of the key attributes of Japanese tofu is its high protein content. In fact, a half-cup serving (126g) provides approximately 21.8 grams of protein¹. This makes it a fantastic option for individuals seeking plant-based protein sources in their diet.

Moreover, Japanese tofu is a good source of various essential nutrients. Here are the key nutrients found in tofu:
