Company history

On 10 May 1933, Tateishi Kazuma, then thirty-three, opened Tateishi Electric Manufacturing in the Higashinoda district of Osaka. The staff was two — one workman, one apprentice — and the plant was the earth-floored ground level of a row house whose upper storey the family lived in, with a vise bolted to a workbench. The first product was a timer for X-ray photography, of Tateishi’s own design. The market for it proved far too small, and he switched quickly to protective relays for the electric-power industry, billing the firm as Japan’s first and only dedicated relay works. The pivot took: a new plant followed in Nishiyodogawa in 1936, and by 1945 the company employed 250.

In May 1945 the Osaka plant burned down in an air raid before the war ended. Tateishi had already taken over a film studio at Omuro in Kyoto and was converting it as a dispersal plant, so the company moved its base there — the direct reason OMRON is headquartered in Kyoto today, and the origin of the brand name itself, coined from the place name Omuro. With the surrender, demand for relays vanished. The firm reincorporated in May 1948 as Tateishi Electric Co., Ltd. with capital of ¥2 million, but the rebuild stalled, and by 1950 the payroll had fallen to thirty-three people. Recovery came only as orders for power equipment returned.

In 1952, with the rebuild still unfinished, Tateishi heard from the efficiency scholar Uno Yoichi about American factories running without workers on the floor. Japan did not yet have the word automation. He decided it was the promising market of the future, and in 1955 — aged fifty-five, running a company of 110 people and ¥240 million in annual sales — set out to open a market that did not yet exist, developing in-house the functional components that control systems are built from: microswitches, relays, sensors. The accompanying rule that research on new products came before everything else is the origin of the R&D-first posture OMRON has run on since.

To carry the expansion, Tateishi devised in January 1955 his own organizational theory, the producer system. Sales and research were split off as separate companies and production was devolved to independent, single-line plants — eventually nine manufacturing subsidiaries. He framed this not as mere spin-off but as a management philosophy for giving individuals a place to show what they could do. Sales rose roughly tenfold over the five years the system took hold. The trademark OMRON was adopted in 1959, and in April 1962 the company listed on the Kyoto and Osaka exchanges, pairing development spending with access to capital.

The control technology built for automation components then produced a run of world firsts in applied products: the first contactless proximity switch in 1960, the first electronically actuated traffic signal in 1964, and in March 1967 the world’s first unmanned railway station at Hankyu’s Kitasenri — automatic ticket gates and vending machines together, the template for railway automation in Japan. A credit-card vending system followed in 1965, its technology exported to Canteen of the United States. Factory automation and social systems, two of the pillars OMRON still stands on, took shape here. The third began in 1963, when the company brought Hans Selye, the world authority on stress, to Japan as a private firm and signed a joint-research contract with the University of Montreal’s Institute of Experimental Medicine; work on measuring meridians and the pulse electronically led to a simple blood-pressure meter, the first OMRON unit in 1973, and later the electronic thermometer line. Tateishi read all of it as the corporate motto — “let us make a better society” — put into commercial form, as he did the disabled-employment subsidiary OMRON Taiyo (1972) and the powered prosthetic arm developed with Tokushima University for thalidomide-affected children. In 1988–89 the company added a second head office in Tokyo and set up regional holding companies in the Netherlands, Singapore and the United States.

In January 1990 the corporate name was changed to OMRON Corporation. The brand adopted in 1959 had long since outrun the founding family’s name on the door, and the change also served the push toward a single global identity. The head office moved within Kyoto in 1991 and consolidated into the OMRON Kyoto Center Building in 2000. Manufacturing moved too: the first wholly owned Chinese plant, at Dalian, started up in 1993, a China regional holding company followed in 1994 and was upgraded to a China head office in 2002, and the Shanghai plant became the global core site for control-system products in 2006. Through the 2000s, assembly and board mounting for the control business concentrated in China.

In April 1999 OMRON scrapped its divisional structure for a company system — the first fundamental redefinition of its organization since the producer system of 1955 — giving each internal company its own profit responsibility. Healthcare was carved out as OMRON Healthcare in 2003, putting the blood-pressure business on its own footing. In October 2004 the company both bought and sold in the same month: it acquired Italy’s BITRON INDUSTRIE to expand automotive electronics, and transferred its ATM and information-equipment business into a joint venture with Hitachi, Hitachi-Omron Terminal Solutions. Further acquisitions in 2005–08 added medical measurement, LCD backlights and semiconductors.

Revenue reached a record ¥763.0 billion in the year to March 2008, and then the Lehman shock reversed everything. Sales fell 17.8% to ¥627.2 billion in the year to March 2009 and OMRON booked a net loss of ¥29.1 billion, among the largest in its history — the direct result of a collapse in factory-automation demand hitting a company whose earnings leaned on control equipment. In the recovery the group split itself further into separate legal entities — switches, automotive electronics and social systems each becoming its own subsidiary in 2010 — a structure that would later make divestment straightforward. Yamada Yoshihito became president in 2011.

Under Yamada, OMRON bought its way up the factory floor. Delta Tau Data Systems, a US motion-control maker, was acquired in September 2015, and Adept Technology — with its autonomous mobile robot technology — a month later, taking the company into industrial robotics proper. Sentech (industrial cameras) and Microscan Systems (industrial code readers) followed in 2017. The logic was to add robots, machine vision and code reading to the existing controller-sensor-servo line and supply the upper layers of factory automation whole. OMRON SINIC X was set up in 2018 to run advanced research in AI and robotics.

The divestments ran in parallel. The laser-processing subsidiary went to TOWA in 2018 and 80% of the contract-electronics unit to Advantech in early 2019. In October 2019 OMRON sold the whole of OMRON Automotive Electronics to Nidec — a complete exit from the automotive business it had spent fifteen years building since the BITRON purchase. In March 2021 it sold its entire stake in Hitachi-Omron Terminal Solutions to Hitachi, leaving ATMs as well, and transferred the MEMS business to Mitsumi that October.

Yamada framed this not as simple disposal but as selection and dispersion: choose fewer businesses, then deliberately spread supply chains and risk within the ones you keep. The preference was for clarity of portfolio over scale of revenue. Tsujinaga Junta became president and CEO in 2022; that year OMRON took a capital and business stake in the medical-statistics firm JMDC, moving into data health, and moved to the TSE Prime market. Revenue in the year to March 2022, the last of Yamada’s tenure, was ¥762.9 billion with net profit of ¥61.4 billion.

The year to March 2023 was the best OMRON had ever had: revenue of ¥876.0 billion and net profit of ¥73.8 billion. JMDC was consolidated as a subsidiary in October 2023, bringing a data-health platform in-house. The reversal came immediately after. Control-equipment demand turned down, and OMRON fell further than its peers — Keyence and SMC also saw profits drop, but nothing like this. Net profit fell to ¥8.1 billion in the year to March 2024 on revenue of ¥818.7 billion.

The cause was the shape of the good years. Selling complex solutions to the largest, most advanced customers, and going deep into China, delivers high growth while those customers are growing and leaves the seller fully exposed when the cycle turns. In 2024 OMRON announced the structural reform NEXT 2025: roughly 2,000 job cuts, including the first voluntary-retirement programme since 2002, taken while the company was still profitable, and about ¥30 billion of fixed costs removed. Cutting fixed costs does not by itself restore competitiveness, and the gap to Keyence remains wide; whether the reset works depends on how far the reduction of the China concentration and the push into Western markets and non-manufacturing customers actually carries.
