Company history

In December 1906 Yamaguchi Takehiko opened Yamatake Shokai in Kyobashi-ku, Tokyo — today’s Yaesu, Chuo-ku — as a direct importer of European and American machine tools and cutting tools, agent for firms such as Germany’s Schuchardt & Schütte. It was a trading house, not a manufacturer. When the yen slid and imported machinery turned expensive, the margin in simply buying abroad and reselling at home thinned, and Yamatake went looking for the answer in localisation: it brought in instruments from the Brown Instrument Company of the United States as unfinished goods and assembled them in Japan.

The switch happened almost at the moment the firm incorporated, in July 1932; the first assembly floor was an office room in the Yaesu Building. In 1933 it absorbed the Omori machine works and opened an instrument works at Omori, and a trading company became an instrument maker by converting what it had learned as an importer into manufacturing of its own. Control valves for Nippon Oil were localised in 1936; in April 1939 a dedicated instrument plant went up in Nishi-Rokugo, Ota-ku — the present Kamata works — for full-scale domestic production of Brown instruments.

In April 1942 the company was renamed Yamatake Kogyo and its trading arm was split off, separating manufacture from commerce. War narrowed it further: the Omori plant, its mainstay, was designated for reparations removal as a machine-tool factory, so machine tools were abandoned and instruments became the whole business. In August 1949, under the Enterprise Reconstruction and Reorganization Act, Yamatake Kogyo was liquidated and a second company, Yamatake Keiki, was created to restart the manufacture and sale of instruments. Four decades of importing the West’s newest technology, plus a wartime-won ability to build, were what the postwar instrument maker had to work with.

In January 1953 Yamatake Keiki signed a technical and capital agreement with Honeywell Inc. and entered a joint venture on a 50% shareholding. Honeywell had absorbed Brown during the war, so the alliance was a continuation of the prewar Brown localisation by other means. Postwar Japanese industry had no instrumentation and control technology of its own, and Yamatake wanted the transfer at company level — process and building automation as a body of practice — rather than product by product. Honeywell had asked for 51%; Yamaguchi refused, on the ground that a partnership settled by cumulative voting would never be a good partnership.

The alliance was written into the name itself in July 1956, when the company became Yamatake-Honeywell. Capital markets followed: over-the-counter trading in August 1958, the Tokyo Stock Exchange second section in October 1961, and the first section in February 1969. Having moved earlier than its rivals to bring in a foreign partner, Yamatake set out as a broad automation maker rather than a maker of gauges.

Then came the plants that defined the shape of the business. Fujisawa (April 1961) made microswitches and HVAC controls — the seed of the later building automation business. Yamatake Keiso, founded in October 1963 and later Yamatake Building Systems, added the engineering and installation of HVAC control, joining hardware sales to on-site service. Samukawa (November 1972, now the Shonan works) built control valves for process automation; Isehara (August 1973) built central supervisory systems and control panels for buildings. Across the 1960s and 1970s the source of revenue was replaced: from selling instruments to automating whole buildings and plants under contract.

The separation took twelve years and moved in steps. In March 1990 Honeywell’s stake fell from 50% to 24.15%. That November the technical agreement was replaced by a broader framework agreement, and in October 1997 the framework was broken up again into separate contracts business by business. In July 1998 Yamatake-Honeywell became simply Yamatake, dropping the partner’s name from its own; that October part of the domestic sales organisation was handed to Yamatake Building Systems and Yamatake Industrial Systems. Each step was possible because Yamatake’s own accumulated technology had reached a level where the alliance was no longer load-bearing — and because Honeywell, restructuring its own portfolio through the 1990s, had less and less reason to keep a fifty-fifty venture in Japan.

In July 2002 the capital relationship was dissolved, ending forty-nine years. Honeywell had been the one to propose the sale, and Yamatake bought back its 10.99 million shares in two tranches, in December 2000 and July 2002 — the gap owing less to strategy than to Japan’s rules on treasury stock and to the market. In April 2003 the company reabsorbed Yamatake Building Systems and Yamatake Industrial Systems, swinging back from an operating-subsidiary structure to a single body running three automation businesses as internal companies.

The third of those businesses was bought. Between December 2005 and April 2008 Yamatake took Kinmon Manufacturing — now Azbil Kinmon — through preferred shares, conversion to common stock and finally a share exchange into full ownership. Gas and water meters gave the group a life automation business alongside building automation and advanced automation, extending its reach from industrial customers to household infrastructure. The three-business frame set here has been the skeleton of the group ever since.

In April 2012, more than a century after Yamaguchi opened his import shop, Yamatake renamed itself Azbil Corporation. The coined name compresses automation, zone, builder; alongside it the group adopted “human-centered automation” as its philosophy, a deliberate turn from describing product specifications to describing what automation is for. Three-year mid-term plans followed in 2014–2017 and 2018–2020, and in 2019 a new production building at the Shonan works absorbed the group’s metropolitan-area manufacturing.

In April 2020 Yamamoto Kiyohiro became president, with Sone Hirozumi moving to chairman and chair of the board — execution and oversight pulled apart. The 2021–2024 mid-term plan, run under the banner of “advanced automation,” delivered four consecutive years of higher sales and profits: revenue grew about 31% over the plan to reach $2.1B (¥323bn) in fiscal 2024, and operating profit about 70%, to $289.1M (¥44bn). Governance moved with it — a shift to a company with a nominating committee in June 2022, following the move to the TSE Prime market that April, aligning the board with the expectations of the global investors implied by a target of more than half of sales from overseas.

Concentration came next. In October 2024 Azbil sold its entire stake in Azbil Telstar, the pharmaceutical-equipment business, to Falcon Acquisition under Germany’s Syntegon Technology — accepting a smaller top line in fiscal 2025 in exchange for putting resources behind building and advanced automation. Capital policy was rebuilt in parallel: an eleventh straight year of dividend increases, a payout planned to lift the dividend-on-equity ratio to 5.6%, continued buybacks and cancellations, and treasury shares turned toward employee shareholding. Azbil Vietnam Production was set up in March 2025, and that April a new mid-term plan for 2025–2027, “Evolution and Co-creation,” carried the earnings programme forward into a longer view fixed on 2030.
