Tofu has been part of the Japanese diet for roughly a thousand years, yet the industry that makes it is changing faster than at any time in living memory. Neighbourhood tofu shops are closing, large manufacturers are consolidating, and global demand for plant protein has given producers a reason to invest abroad. The companies that succeed are redesigning tofu for people who did not grow up eating it.
A traditional food with a shrinking base
Tofu is made by coagulating soy milk with nigari (magnesium chloride) or calcium sulfate, then pressing the curds. It arrived in Japan from China and spread through Buddhist temple cooking. By 1782 it was popular enough for an Osaka publisher to release Tofu Hyakuchin, a bestselling book of one hundred tofu recipes.
For most of the twentieth century tofu was made locally and sold the same day. Japan had more than 50,000 tofu producers around 1960. Today the number is roughly 5,000. Supermarket price pressure, ageing owners without successors and rising soybean and energy costs have pushed small shops out, while automated factories have taken their place.
The main varieties
| Type | Description | Typical use |
|---|---|---|
| Momen | Firm tofu, pressed to remove water | Stir-fries, grilling, hot pots |
| Kinugoshi | Silken tofu, set without pressing | Chilled dishes, soups, desserts |
| Abura-age and atsuage | Thin and thick deep-fried tofu | Miso soup, inari sushi, simmered dishes |
| Koya-dofu | Freeze-dried tofu, shelf-stable | Simmered dishes, high-protein ingredient |
The companies driving change
Sagamiya Foods
Based in Maebashi, Gunma Prefecture, Sagamiya is Japan’s largest tofu maker. It grew by investing in highly automated production and by acquiring struggling regional producers. It is also known for marketing: a tofu shaped like a robot from the Gundam anime series became a hit in 2012, and its Beyond Tofu range offers cheese-like products made from soy.
House Foods Group
Best known in Japan for curry roux, House Foods is a major tofu producer in the United States. Its American subsidiary runs plants in California and New Jersey, and the group expanded further in 2022 by acquiring Keystone Natural Holdings, a US maker of tofu and plant-based foods.
Morinaga Milk Industry
Morinaga applied aseptic packaging technology to silken tofu, creating a product that keeps for months without refrigeration. Sold abroad under the Mori-Nu brand through a California-based subsidiary established in 1985, it made tofu practical for retailers far from any tofu factory.
Asahico
Asahico launched Tofu Bar, a firm, seasoned stick of tofu sold in convenience stores and eaten by hand. It has sold tens of millions of units and is a clear example of tofu repositioned as a protein snack.
Koya-dofu specialists
Nagano-based makers such as Asahimatsu Foods and Misuzu Corporation produce freeze-dried tofu. It is lightweight, stores at room temperature and is dense in protein, which makes it one of the easiest tofu products to export.
Why the plant-protein wave matters
Overseas consumers increasingly look for protein that does not come from meat. Tofu fits that demand well. Firm tofu provides around 7 grams of protein per 100 grams, is minimally processed and has a short ingredient list, which appeals to shoppers who have grown wary of heavily processed meat substitutes.
Japanese makers are responding with products designed for new habits:
- Extra-firm and high-protein tofu — easier to cook for people used to meat
- Ready-to-eat formats — bars, seasoned cubes and noodles made from tofu
- Dairy alternatives — soy-based products that imitate cheese and cream
- Longer shelf life — aseptic and freeze-dried products that simplify distribution
The constraints
Fresh tofu is heavy, mostly water and perishable, so exporting it from Japan is rarely economical. That is why the largest players manufacture close to their customers. Raw material is another issue. Japan grows only a small share of the soybeans it consumes, so producers depend on imports, mainly from North America, and are exposed to exchange rates and crop prices. Premium products made with Japanese-grown soybeans therefore carry a meaningful price difference.
What overseas partners should consider
- Local production partnerships — Japanese makers bring process technology and quality control, and need local distribution, sites and staff
- Shelf-stable imports — koya-dofu, aseptic silken tofu and fried tofu products can be imported without a cold chain as demanding as fresh tofu requires
- Equipment and know-how — Japan’s tofu machinery makers supply automated lines, an opportunity for food manufacturers entering the category
- Foodservice — restaurants and meal-kit companies want consistent, firm tofu that holds up in Western-style cooking
Outlook
Japan’s tofu industry is smaller in number of companies but larger in ambition than it was a generation ago. Domestic consolidation will continue, and growth will come from new formats at home and production abroad. For investors and buyers, the most attractive partners are makers that combine traditional quality with products designed for people eating tofu for the first time.
