Company history

Mechanized milling arrived in Japan as a government project — a state mill opened at Kuramae in Tokyo in 1879 with two steam-driven stone mills bought in France. It failed. The machines were sold to a company of former samurai around 1884, moved in 1888 into a building at Fukagawa Ogibashi owned by Amemiya Keijiro, who had seen American milling and built a mill there around 1880 and already shut it. Machine-ground flour was purer than watermill flour but dearer, and the traditional udon market would not pay for it; the only buyers were the army and navy, and the new uses, bread and biscuits. That company dissolved in 1891 and the plant passed to a merchant who also failed.

In 1893 Nanjo Shinrokuro, a bank president and former retainer of the Tatebayashi domain, took it over with others as Tokyo Seifun, opened civilian channels alongside military orders, and used the demand for army rations in the Sino-Japanese War to steady the business. In December 1896 its assets were transferred into Nippon Flour Mills, capitalized at ¥300,000, with 200 barrels of capacity at Fukagawa. That year 89% of Japan’s flour still came from watermills. Japan’s oldest mechanized miller stands not on a run of successes but on three previous failures.

From there it grew by buying mills — Meiji Seifun in 1907, Teikoku Seifun in 1909, and after the First World War a cluster of acquisitions that brought Kobe, Takasaki, Oyama, Moji, Sapporo and Sendai. The Yokohama waterfront mill, the first large coastal plant in Japan, opened in 1924, and by the end of 1926 the company had eleven mills, 16,100 barrels and ¥12.3m of capital. But industry capacity had tripled from pre-war levels, and Nisshin and Nippon between them held more than 80% of it. Overcapacity in a product that cannot be differentiated has only one answer: agree not to produce, and agree the price.

Seven millers signed a production-restraint agreement in 1926, cutting 40–60% of output. Nippon handed sole selling rights to Mitsui & Co. in May 1927, agreed selling prices with Nisshin in October 1928, and in April 1930 the two firms and Mitsui funded a joint sales association. The price of flour was set by agreement, not by market, from then on — until the state took the decision entirely, with a maximum price by ministry notice in 1940 and the Food Control Act of 1942. Overseas expansion into Korea, Manchuria and China through the 1930s ended with the war; the company lost every mill outside Japan, and what remained was five plants at 34% of pre-war capacity.

Nippon Flour Mills listed in Tokyo and Osaka in May 1949. Wheat controls were lifted in 1952, restoring free selling for the first time in twelve years, and by March 1955 the company had ten mills and 22,600 barrels — larger than before the war. But only the selling was free. Wheat was still bought from the government at an official price, and each mill’s allocation was fixed by formula, with the national total set monthly by the ministry. In an industry where neither the input nor its price distinguishes anyone, the only competition left is over what you make from the same wheat, and how cheaply you move it.

The Yokohama mill shows what that meant in practice. By 1966, four production lines ran around the clock at 1,211 tonnes a day, 23% of the company’s capacity and 3.9% of Japan’s. Its silos held 33,000 tonnes, 10,000-tonne ships berthed at its quay, and the 230,000 tonnes of wheat landed there each year were about a tenth of national imports — wheat that belonged to the government the moment it was stored, so the mill was paid to warehouse it, and paid again to ship it inland. Where prices are administered, advantage lives in berths, silos and shifts.

The other answer was to leave flour behind. Nippun Shokuryo was founded in 1955 with the household brand Ohmy; tempura flour followed in 1963 and premixes from 1964 — selling flour with the cooking partly done. Premixes for Mister Donut began in 1971, and frozen food with cream croquettes in 1973. Around these ran a widening group of subsidiaries in trading, machinery and processing, and new mills through the 1970s and 1980s. In 1968 the company was described as splitting the industry with Nisshin at about 25% share and paying a stable 13% dividend under government supervision of both its input and output prices. Stability of that kind has a ceiling; Ohmy and the premixes existed to lift it.

The pattern of these decades was to try a business in a separate company and fold it back in when it grew — or to split it out again when it needed its own accounts. Ohmy was absorbed in 1990, thirty-five years after it was created; a new Ohmy was established in 1998 to take over pasta manufacturing. Company-wide restructuring began in 1993, and in 1996, the centenary, NIPPN was adopted as a communication name — the corporate name itself would not follow for another twenty-five years.

Two routes opened in 1996, the year domestic wheat demand stopped growing. Nippun Reishoku was set up to manufacture frozen food as a standalone business, and the first overseas subsidiary was established in Thailand. In 2000 the company bought Pasta Montana in the United States — a plant in wheat country making pasta to bring home, with a cost structure nothing like the allocated domestic business. In 2013 it acquired Nagano Tomato, a raw material entirely unlike wheat, combinable with its own noodles through pasta sauce.

The financial result was undramatic and cumulative: consolidated revenue from ¥207.9bn in FY2002 to ¥287.1bn in FY2014, up 38%, with recurring profit rising 3.2 times from ¥3.8bn to ¥12.2bn — under 3% annual revenue growth. With input and price fixed at home, all of the growth had to come from frozen food, from overseas and from acquisitions, and all four of those moves were made in this period, one at a time.

On 1 January 2021, at 125 years, the company became NIPPN CORPORATION — dropping the two characters meaning "flour milling" that it had carried since 1896. President Maezuru Toshiya and Chairman Sawada Hiroshi called it a "second founding." By revenue the claim held: milling was ¥101.7bn against ¥166.6bn of food in FY2015, and ¥120.0bn against ¥243.7bn by FY2026, a third against two thirds. By profit it did not. Segment profit in FY2021–23 ran ¥5.1bn, ¥6.2bn and ¥7.5bn in milling against ¥4.3bn, ¥4.1bn and ¥3.4bn in food — milling’s share rising from 55% to 69% in the three years right after the name changed.

The reason is the wheat system. About 90% of wheat consumed in Japan is imported by the state and sold on to millers, at a price revised twice a year from a moving average of government purchases plus port costs and a markup. That price went from ¥51,930 in April 2021 to ¥72,530 a year later — up about 40% — and back to ¥62,520 by April 2026. Milling passes the change into flour prices on the same schedule; frozen and prepared foods must negotiate with retailers, so they absorb it for longer. The imbalance has since evened out — ¥9.2bn versus ¥9.3bn in FY2025, ¥9.5bn versus ¥9.1bn in FY2026 — and the FY2026 plan puts food ahead at ¥11.4bn against ¥6.8bn. Whether the conversion is complete can only be judged after a full wheat cycle leaves that balance standing.

Alongside this, the balance sheet is being rebuilt. Cross-shareholdings fell from 119 issues in FY2021 to 78 in FY2024 and from 30.7% of consolidated net assets to 24.2%, with a target below 20% by the end of FY2026. Gains on securities sales of ¥13.5bn in FY2024, and ¥4.7bn plus ¥8.7bn of fixed-asset gains in FY2025, lifted net profit to ¥26.4bn and ¥24.8bn — special gains exceeding 60% of operating profit two years running — and the proceeds are going into plants: the Chita mill, built for large grain ships, started up in February 2026, a new Utah mill in February 2025, and the group’s largest frozen food plant is due at the end of FY2026. Underneath, revenue rose to ¥400.5bn, ¥410.9bn and ¥418.4bn across FY2024–26 with operating profit of ¥20.3bn, ¥21.5bn and ¥22.1bn.

The 1968 record put the company’s share at about 25%. In FY2024 its share of domestic flour sales was 25.0%, still second. In between, the number of mills in Japan fell from around 3,100 in 1951 to under ninety, and companies from 129 to 60 — yet the top four still hold 81.8% between them. That durability rests entirely on a system in which the state buys and sells the wheat. If the system changes, 130 years of stability converts directly into constraint, and the long-term goal of ¥500bn of revenue by FY2030, like the name change itself, is a preparation for that day.
