Company history

Daikin began in 1924, when Yamada Akira — a former factory manager at the Osaka Artillery Arsenal — left government service at forty and set up a small partnership, Osaka Metal Industries (Osaka Kinzoku Kogyosho), on the Namba-Shinkawa canal in Osaka with fewer than fifteen employees. It started out making radiator tubes for aircraft, but growth was slow and the early going was hard. On the recommendation of his former arsenal superior, Yamada secured the status of an army-designated factory, won mass orders for artillery shells, and rode the prewar swell of military demand into a fast-growing munitions venture — its parts good enough that the arsenal extended its dealings to the Manchurian arsenal, and the firm came to be called a pioneer of the Manchuria trade.

In 1933 the turn that would remake the company arrived from an unexpected quarter. Ota Tomio, a retired navy rear admiral serving as technical adviser, seized on a newspaper report that the U.S. Navy had adopted a new refrigerant, Freon gas, aboard its submarines, and pressed the board hard to take up fluorocarbon research. Daikin already had a foothold in refrigeration — it had put out a methyl-chloride machine, forerunner of today’s Daikin refrigeration units, under the Mifujireitor name — but for a metalworker of artillery shells to step into the wholly unknown field of chemical plants was a difficult technical leap, with only a handful of in-house chemists and limited equipment. Yamada backed Ota’s counsel all the same, and in 1935 Daikin achieved Japan’s first domestic production of fluorocarbon. From the founding years, then, two technologies of different origin — metalworking and refrigerant chemistry — grew up side by side, and the second planted the first seed of a break from dependence on military demand.

As it steadied itself, the partnership drew an offer of investment and support from Sumitomo Metal, which had watched it closely; hoping for future growth and credit, Yamada accepted, and the firm entered the Sumitomo orbit. In February 1934 it was incorporated with capital of one million yen as Osaka Metal Industries Co., Ltd., and Daikin fixes that day as its founding — a second point of departure. It absorbed the old partnership in 1938 and, after the war, in 1953 moved its head office to the present site and re-founded itself as a modern company. Drawing in zaibatsu capital without letting go of control of its own management, the firm built the capital base that would carry it from munitions toward air conditioning.

The war’s end stripped Daikin of its core products and pitched it into a grave crisis; through the reconversion to civilian demand it fell to paying no dividend at all. When the Korean War broke out in 1950, an order suddenly opened for 81-millimeter mortar shells from the U.S. military. Voices inside the company were wary of leaning on wartime windfalls again, but president Yamada gave the blunt order to “win the contract by any means,” pushed hard into the special demand, and pulled the firm out of its dividendless crisis in short order — the U.S. military ultimately taking some 1.99 million shells.

The decisive move was what Daikin did with the money. Rather than plow the Korean windfall back into shell production, it channeled the funds into the peacetime civilian fields of refrigeration, air conditioning and fluorocarbons — a choice that set the direction of the postwar company. Through the 1960s it built out a full-line air-conditioning maker handling both commercial systems and room air conditioners, developed domestic production at the Kanaoka works and, step by step, a domestic sales network, and completed the fundamental change of character from a shell maker into an air-conditioning maker. It entered the room-air-conditioner business in 1958 and, in 1963, took the name it still carries, Daikin Industries. The chain of turns — from a munitions venture through the Korean special demand to an air-conditioning specialist — laid the historical ground for its later leap into a global air-conditioning company.

The 1970s opened with a hard test. The oil shock dragged Daikin to an ordinary loss of $7.7M (¥2bn) in 1975, and it was forced through a painful retrenchment — cutting some 700 jobs in all and redeploying surplus factory workers into its air-conditioner sales companies. Rebuilding through the late 1970s, it invested in technology, opening a new electronics center inside the Kanaoka works in 1979, and recovered its footing in both commercial and household air conditioning at home. Coming through the crisis strengthened the company’s constitution and taught it, across the whole organization, the value of product differentiation and market focus — a lesson that would shape its later choices abroad.

In 1995 Daikin entered China through a joint venture with a Shanghai sewing-machine maker — a partner unrelated to air conditioning, because ventures with local air-conditioning makers had already been locked up by the American firm Carrier. The market was a battlefield of more than four hundred firms in consumer air conditioning, so Daikin avoided the war of volume and specialized in commercial systems for government offices and businesses, a differentiation that proved a strategic success. Its end-to-end service, from design and installation through maintenance, won high marks in China’s public-sector and office market, and this focus model worked through the 2000s as a stable, high-margin engine — and as an important reference when it came to build the European strategy.

Daikin had set up a subsidiary in Belgium back in 1972, but its full European push began in 1998, applying the same basic idea it had tested in China: specializing in commercial systems for the institutional market. Where China had called for building its own direct-sales dealer network, Europe’s climates and business customs differed country by country, so Daikin instead bought up existing local sales companies one after another — in Germany, France, Italy, Spain, Belgium and the Netherlands — and assembled a continent-wide network in short order. As tightening refrigerant regulation through around 2005 raised demand for high-efficiency commercial systems, the inverter and refrigerant strengths Daikin had honed at home found a favourable market, and its European success became a valued precedent for the North American M&A to come.

In 2006 Daikin made its full entry into North America by acquiring the Malaysia-based global major OYL Industries for roughly $2.1 billion, reaching the market through OYL’s McQuay unit. But its North American share stayed limited: McQuay’s strength lay in commercial systems, and management came to see that it could not build a foothold in the U.S. residential market on that alone. In November 2012 Daikin therefore acquired Goodman Global Group — holder of about a 25% top share in U.S. residential air conditioning — in the roughly $3.7 billion Goodman acquisition, spending more than it had on OYL to enter the North American consumer market in earnest.

Goodman’s value lay in handing Daikin an already-established top share in one of the world’s largest markets, U.S. residential air conditioning, and letting it cover both the commercial and residential fields in North America for the first time. Houston-based Goodman ran a strong dealer network across the American South, and Daikin set about pushing its home-grown R32 refrigerant and inverter technology through it. By the 2020s Daikin Applied Americas had become the core of the region’s applied business, acquiring firms with liquid-cooling technology that chills servers directly, lifting the data-centre share of sales toward 20% and making North America the largest growth engine in group results.

On technology, Daikin led the industry’s move away from older fluorocarbons ahead of the world: in 2012 it launched room air conditioners using the new refrigerant R32, whose global-warming potential is about a third of the earlier R410A, and it opened part of its R32 patents to rivals for free to speed the standard’s spread — pushing its own environmental technology into the industry’s default position. Under a two-man structure from 2014, with Masanori Sogo as president and chief operating officer and Noriyuki Inoue as chairman and chief executive, Daikin held its high-margin footing through global inflation with steady price rises. It grew into one of the world’s largest air-conditioning makers, marked its hundredth year in 2024, and that June handed the presidency to Naofumi Takenaka — the first change in over a decade — as Inoue moved to honorary chairman, even while North American residential demand and U.S. tariff policy loomed as the next era’s risks.
