Japan Frozen-Food Producer Plans ¥2.95 Billion Tofu Factory Expansion

By AgriLinkage Food | October 18, 2026

A Japanese frozen-food producer plans to invest ¥2.953 billion in an expanded tofu-processing operation in Shimane Prefecture, directing almost three-quarters of the disclosed capital to production assets rather than the building itself.

Shimane’s government announced the plan on October 16 after Tsubuki Co. (都吹株式会社) decided to enlarge its factory at the Iwami Airport Factory Park in Masuda. The project is intended to meet rising demand for frozen silken atsuage—thick fried tofu—and a new order for frozen tofu.

The prefecture’s detailed location plan puts operations at the expanded facility in April 2027. It lists ¥2,953,328,000 in investment and 23 additional permanent jobs over three years. The filing does not disclose tonnes of new capacity, customer identities or expected sales, so none should be inferred from the capital figure alone.

What the investment buys

Plan item	Official figure	Agrilinkage calculation
Total fixed investment	¥2.953328 billion	100%
Building work	¥799 million	27.1% of total
Depreciable production assets	¥2.154328 billion	72.9% of total
Additional building area	523.58 m²	15.8% of the reported 3,312 m² building area
Permanent workforce	43 to 66	53.5% increase

The investment mix is the clearest indication that this is principally a processing-line expansion, not just additional floor space. Buildings account for ¥799 million, while machinery and other depreciable assets account for ¥2.154 billion. Agrilinkage calculates those shares at 27.1% and 72.9%, respectively.

The 523.58 m² addition equals 15.8% of the 3,312 m² building area reported in the plan. The filing describes the work as construction and modification within the existing 10,000 m² site, rather than a new greenfield factory.

Twenty jobs arrive with start-up

Employment is scheduled to rise from 43 permanent workers at application to 63 when the expanded operation starts, followed by three more employees during the first operating year. The plan shows no additional increase in years two and three, leaving the stated three-year total at 66.

That is a 53.5% workforce increase from the current prefectural employment base. Twenty of the 23 jobs—87%—are expected to be in place at start-up, making staffing and training before April 2027 a practical execution test rather than a distant employment promise.

Dividing total investment by net new jobs gives about ¥128.4 million per additional permanent position. That is a capital-intensity indicator, not a job cost or a measure of economic return: the investment also replaces or expands productive capacity used by the existing workforce.

Why frozen tofu is an industrial product

Frozen tofu is not simply chilled fresh tofu placed in a freezer. Commercial freezing, formulation and handling have to control ice-crystal formation, water loss and texture change. The attraction for food-service and prepared-food customers is a longer usable life, repeatable portioning and a product that can move through frozen distribution alongside other ingredients.

Atsuage adds another processing layer because tofu is fried to develop a browned exterior while retaining a softer interior. Scaling such products requires control over moisture, oil management, cooling and freezing, as well as hygiene and packaging. The prefectural filing identifies frozen silken atsuage and frozen tofu as the output categories, but does not specify the exact equipment being purchased.

Agrilinkage’s guide to freezer burn and frozen-food packaging explains why temperature stability and moisture-barrier performance remain important after food leaves the production line. The new filing gives no cold-store or packaging specification, so those elements should be treated as open operational questions.

A second-stage factory expansion

Tsubuki was established in 1984 and manufactures prepared frozen foods, tofu products and confectionery. It opened the Shimane factory in 2019 as a production base for frozen silken atsuage. According to the prefecture, that operation created more than 40 jobs over seven years and the company now employs 337 people overall.

Masuda city’s profile of the original factory described it as the company’s second production base after its Hiroshima headquarters operation. The new plan therefore expands an established line rather than testing an unproven site.

Shimane Prefecture and Masuda city say they will support the project with finance and workforce recruitment under the prefecture’s business-location framework. The announcement does not quantify that public support, so the ¥2.953 billion investment should not be described as wholly private or publicly subsidized without further disclosure.

What the announcement does not establish

The investment is approved as a location plan, but the prefecture has scheduled the formal certificate presentation and memorandum signing for October 23. That distinction matters: the October 16 release records the company’s decision and the government’s planned support, while construction completion and April 2027 operations remain future milestones.

The company and prefecture did not publish existing or future output in tonnes, utilization rates, energy demand, soybean sourcing, customer contracts or export allocation. Without those figures, it is impossible to calculate the percentage capacity increase, raw-soybean requirement or effect on Japan’s tofu trade.

The most useful next disclosures would be the new line’s rated throughput, commissioning progress, food-safety certification, cold-storage requirements and customer mix. Those figures would show whether the project mainly deepens domestic food-service supply, supports prepared-food exports or both.

Why processors should watch the project

For frozen-food operators, the plan is a compact example of how a regional factory can move from initial production to an asset-heavy second phase. The small addition in floor area relative to the large equipment budget suggests that the economic value is expected to come from line capability and throughput inside the existing site.

For suppliers, the relevant opportunities extend beyond tofu-making machinery to frying, rapid cooling, freezing, conveying, inspection, packaging, sanitation and cold-chain services. Yet those opportunities are not confirmed purchase orders until the company discloses its procurement package.

For local officials, the main measurable outcomes are straightforward: whether operations begin in April 2027, whether the initial 20 hires materialize, whether the remaining three positions follow, and whether the plant can meet the new frozen-tofu demand that justified the expansion.
