Toho History


Our Story

We are a family owned, global business with roots in Nagoya, Japan dating back to 1819 when the Tomita family seized an opportunity to distribute imported American dry goods in feudal Japan. With a legacy of over 200 years in business, we extend to our customers the same commitment to innovation as that of our predecessors.

The Toho Story

In 1819 in Nagoya, Japan, the Tomita family, founders of modern-day Toho Technology, saw a new business opportunity and began distribution of imported American dry goods into feudal Japan. As markets and society changed, the business operation also evolved taking advantage of economic growth in land development, raw materials, and commercial industries.

In the first 100 years of business success, the company expanded operations and continued to meet the growing need for newer products and innovative solutions. In mid-20th century Japan, Toho soon emerged as a distributor and manufacturer of industrial electronics and new technologies with a foundational relationship with Hitachi and other local electronics manufacturers.

In the latter years of the 20th century, Toho diversified operations to include manufacturing of inspection and wet process systems for growth market semiconductor, material characterization, flat panel display and dynamic glass suppliers. Operations in industrial electronics, contract manufacturing, and automation also expanded to meet market demands in microelectronics, automotive and various industrial market segments.

Toho’s Metrology and Wet Process businesses have broadened its product portfolio to include sophisticated cleaning and inspection systems. Since the late 1990’s Toho’s processing and inspection businesses have been further enhanced with consecutive acquisitions and technology transfers from leading American Fortune 500 companies like KLA-Tencor, Nanometrics, Zygo Corporation, Becton Dickinson and other global leaders in technology.

As in the past, Toho continues to dynamically grow and develop new business operations in mature and emerging markets. New businesses have been expanding in China since 1994 and in the United States since 2001 with the establishment of Toho Technology Inc. in Chicago Illinois. Recent operations have been established in Korea, Taiwan, Singapore and Indonesia as opportunities in Asia continue to expand.

Embracing the entrepreneurial spirit of its founders over 200 years ago, Toho continues to pioneer its way toward the next generation of business and technology with its recent food pathogen detection operation; CERTUS focused on revolutionizing the way food producers and laboratories protect the world’s food supply and people from foodborne illness.

Toho Technology is committed to meeting global demands for extremely sophisticated and reliable technological solutions in a wide variety of industrial markets. To fulfill this need, Toho Technology continues to aggressively invest in people, technologies, and operations that will meet the challenges of tomorrow.
