The company profile above reflects OKI’s current corporate information; some figures use different reporting dates, so employee numbers can vary between official publications.

OKI is fundamentally a Japanese technology company rather than simply a printer manufacturer.

The company’s roots are in the development of telecommunications equipment in Japan during the late 19th century. Over more than 140 years, OKI moved through several technological eras: telephones and exchanges, radio and telecommunications equipment, computers, electronic components, semiconductors, ATMs, network systems, printers and, more recently, infrastructure-oriented digital and electronics solutions.

Today, the OKI brand represents the broader corporate group, while printers and printing solutions remain an important commercial product area.

OKI’s current business organization includes Public Solutions, Enterprise Solutions, Component Products and Electronics Manufacturing Services (EMS).

Kibataro Oki

OKI traces its history to Kibataro Oki, an engineer and entrepreneur who recognized the importance of telecommunications during Japan’s rapid modernization in the Meiji era.

In January 1881, he established Meikosha, Ltd. in Tokyo. This company is regarded by OKI as the predecessor of today’s Oki Electric Industry.

At the time, Japan was still developing its domestic telecommunications industry. Oki and his engineers worked on telephone-related technologies and equipment, helping establish domestic manufacturing capabilities.

In 1889, Meikosha changed its name to Oki Electric Works. The company subsequently expanded into telephone equipment, wires, switching systems and other electrical technologies.

One particularly important milestone came in 1896, when OKI delivered Japan’s first in-line multiple switchboard to the Tokyo Naniwa-cho telephone substation.

This telecommunications heritage is important for understanding OKI: its original identity was not printing, but connecting people and systems through technology.

During the early 1900s, OKI expanded its telecommunications manufacturing activities. Important developments included:

• Telephone equipment
• Electric wires
• Telephone exchanges
• Automatic switching systems
• Radio-related equipment
• Telegraph equipment
• Telecommunications infrastructure

In 1912, Oki Electric Co., Ltd. was established, and in 1917, Oki & Co. and Oki Electric were merged.

The company continued developing automatic telephone exchanges and other telecommunications technologies during the 1920s and 1930s. This period established OKI’s reputation as an engineering-oriented Japanese electronics manufacturer.

Like many Japanese industrial companies of the period, OKI’s manufacturing activities were affected substantially by World War II. Some of its factories were designated as munitions facilities, while parts of its manufacturing infrastructure were damaged during air raids. After the war, the company underwent restructuring.

A major corporate milestone occurred in 1949, when Oki Electric Industry Co., Ltd. was established in its modern corporate form.

OKI subsequently returned to civilian telecommunications and electronics production and expanded its technological capabilities during Japan’s postwar economic growth.

During the 1950s and 1960s, OKI increasingly moved beyond conventional telecommunications. The company worked on:

• Transistor technology
• Electronic exchanges
• Computers
• Electronic components
• Data communications
• Teletypewriters
• Banking terminals
• Semiconductor technology

In 1961, OKI completed development of the OKITAC-5090 general-purpose computer and marketed the OKITYPER 2000 electric teletypewriter.

This was an important transition: OKI was becoming a broader electronics and information-technology company, rather than remaining solely a telecommunications-equipment manufacturer.

Printing became one of OKI’s most recognizable businesses during the latter half of the 20th century. OKI developed various printing technologies, including:

• Dot-matrix printers
• Thermal printers
• Fax machines
• Monochrome printers
• Color printers
• LED-based printing systems

A particularly important technology was LED printing. OKI states that it developed the world’s first LED head as a light source for printing in 1981.

This technology became one of the defining characteristics of OKI printers.

Traditional laser printers use a laser beam and optical scanning system to write an image onto a photoconductor. OKI’s LED printing technology uses an array of LEDs to expose the image.

In simplified form:

Digital document → LED array → photoconductor → toner → paper

The technology can provide a relatively compact printing mechanism because the optical system does not need a mechanically scanned laser beam. This became an important part of OKI’s printer engineering philosophy, particularly for compact, durable business printers.

OKI has continued to emphasize the advantages of LED technology, including compact design, durability and energy efficiency.

Today, when consumers hear the name OKI, printers are often the first product category that comes to mind. The company’s printer business has historically focused more heavily on business and professional printing than on mass-market consumer inkjet products.

Its products have included:

Office Printers

Designed for normal business document printing.

Multifunction Printers

Combining printing, scanning, copying and sometimes fax functionality.

Color Printers

Designed for professional documents, marketing materials, labels and other color applications.

Monochrome Printers

Focused on high-volume black-and-white business printing.

Industrial/Specialty Printing

Used for applications such as labels, signage, graphics and other specialized printing requirements.

Dot-Matrix Printers

OKI has also maintained a long history in impact printing, particularly for specialized business environments.

The company describes its printer business as being particularly focused on professional, in-house printing solutions. 1

A major characteristic of OKI’s printer strategy is durability and practical business use. Rather than competing primarily on inexpensive consumer printers, OKI has historically emphasized characteristics such as:

• Reliability
• Long operating life
• Relatively simple mechanical design
• Compact LED printing systems
• Professional color printing
• High-volume printing
• Specialized media handling
• Low maintenance
• Business-oriented workflows

OKI’s own strategic documents identify durability, space-saving design and simple structures that facilitate maintenance as important strengths of its printer business.

Printing is only one part of OKI. The modern OKI Group operates across several technology areas.

Public Solutions

OKI develops systems for public infrastructure and organizations. These can involve transportation, communications, disaster-management systems, public-sector infrastructure, monitoring and operational systems. The broader objective is to use technology to improve the safety, reliability and efficiency of infrastructure.

Enterprise Solutions

This area focuses on business and organizational customers. It includes technologies associated with communications, network systems, business communications, financial institutions, contact centers, operational systems and enterprise IT. OKI has a particularly long history in telecommunications and financial systems.

Component Products

OKI manufactures and develops electronic components and related technologies. Its historical technological expertise has included semiconductor devices, LEDs, sensors, telecommunications components, electronic components and edge devices. The company’s current strategy places considerable emphasis on edge devices and infrastructure-related sensing technologies.

Electronics Manufacturing Services (EMS)

OKI also provides electronics manufacturing services, producing electronic assemblies and systems for other companies. This involves manufacturing technologies such as printed circuit boards, electronic assemblies, cables, production engineering and specialized electronics manufacturing. This part of the business allows OKI to operate not only as a product brand but also as a technology and manufacturing partner.

OKI’s current corporate profile also identifies Defense Systems and Social Infrastructure among its major operations. This reflects the company’s historical relationship with telecommunications, electronics and highly reliable infrastructure systems.

Its technology can therefore be found in areas that ordinary consumers may never associate with the OKI name. In other words, the OKI printer on an office desk is only one visible part of a much larger Japanese technology company.

Financial institutions have also been an important part of OKI’s history. The company developed technologies for banking terminals, automated teller machines, financial communication systems, branch systems and payment-related infrastructure.

OKI’s historical timeline records the development of banking terminals during the 1960s and later the introduction of ATM systems. This is one reason OKI is better understood as an infrastructure and electronics company rather than simply a printer manufacturer.

OKI began expanding outside Japan relatively early. Its international activities have included telecommunications projects, overseas technology partnerships, printer sales, manufacturing, regional subsidiaries and electronics businesses.

The company established overseas operations in markets including the United States and Europe during the 20th century. For example, OKI established Oki Electric Overseas in the United States in 1972 and Oki Electric Europe GmbH in Germany in 1973.

Today, OKI operates internationally through a network of subsidiaries, offices and business operations.

OKI’s current brand statement is “Open up your dreams”.

According to the company, the statement represents OKI’s commitment to creating an information society in which people can achieve their hopes and ambitions while enjoying greater safety and peace of mind.

The brand is therefore intended to communicate more than technological capability. It emphasizes trust, social contribution, safety, reliability, innovation and customer partnership.

In 2026, OKI announced a redefinition of its corporate philosophy as part of its new management plan. The new framework consists of four elements:

The new philosophy builds upon the entrepreneurial spirit of founder Kibataro Oki and emphasizes anticipating societal change and creating new value through people and technology.

The corporate name derives from Oki, the surname of founder Kibataro Oki. The company is formally known in English as Oki Electric Industry Co., Ltd. The short form OKI has become the international corporate and product brand.

So, despite the familiar appearance of the four-letter name, OKI is not originally an acronym in the usual sense. It is derived from the founder’s name.

Historically, the printing business was strongly associated with Oki Data Corporation / OKI Data, particularly in international markets. The printer business has used names such as OKIDATA and later increasingly consolidated around the OKI brand.

OKI’s historical record notes that the OKI Data Group transitioned back to the OKI brand in 2011. 2 This explains why older printers and documents may carry names such as OKI Data, OKIDATA or Microline, while newer products generally use the unified OKI branding.

Some of the technologies associated with OKI include:

LED Printing

Probably the most distinctive OKI printing technology. It uses a fixed LED array rather than a conventional laser-scanning optical mechanism.

Toner-Based Color Printing

OKI has developed color toner printers aimed at professional and business users.

High-Durability Printing

The company has emphasized long-life components and robust printer designs.

Specialty Media

Some OKI printers are designed to work with media beyond ordinary office paper, including labels and other specialized materials.

Impact Printing

OKI has a long history in dot-matrix/impact printing, especially for specialized business applications.

A simplified timeline looks like this:

• 1881 — Kibataro Oki establishes Meikosha, the predecessor of OKI.
• 1889 — Meikosha becomes Oki Electric Works.
• 1896 — OKI supplies an important multiple switchboard installation in Tokyo.
• 1912 — Oki Electric Co., Ltd. is established.
• 1917 — Oki & Co. and Oki Electric merge.
• 1949 — Oki Electric Industry Co., Ltd. is established in its present corporate form.
• 1961 — OKI develops the OKITAC-5090 computer and OKITYPER 2000.
• 1970s — OKI expands its fax, computer, telecommunications and printing technologies.
• 1981 — OKI develops its first LED print head, a landmark in LED printing.
• 1980s–1990s — Expansion into PCs, ATMs, digital switching, semiconductors and networking.
• 2000s — Further globalization and development of printers, telecommunications and semiconductor businesses.
• 2011 — OKI Data transitions back to the OKI brand.
• 2020s — Greater emphasis on infrastructure, edge devices, EMS and specialized business solutions alongside printers.
• 2026 — OKI introduces a new management plan and redefines its corporate philosophy around “Shaping Next for Society.”

As of 2026, OKI is a large Japanese technology group rather than a pure-play printer company. Its current corporate profile lists activities spanning social infrastructure, network infrastructure, defense systems, financial and payment solutions, component products and electronics manufacturing services.

For FY2025, OKI reported consolidated net sales of approximately ¥452.5 billion, with the Tokyo Stock Exchange listing the company under securities code 6703.

At the same time, OKI continues to develop and sell printers. For example, in January 2026, OKI Southeast Asia announced the B433 and B513 monochrome A4 printers, targeting workplaces and sectors such as retail, healthcare, logistics, professional services and the public sector.

OKI occupies a somewhat distinctive position. It is not primarily a consumer electronics brand in the way that companies such as HP, Canon or Epson are commonly perceived. Instead, OKI has historically concentrated on business printing and specialized professional applications.

Its differentiation has often been based on LED technology + durability + business-oriented design + specialized printing + relatively straightforward maintenance. This strategy is especially relevant in environments where printers are treated as production equipment rather than occasional household devices.

Engineering Heritage

OKI has more than 140 years of technological history, beginning with telecommunications.

LED Printing Expertise

Its early development of LED print heads is one of its most distinctive technological achievements. 3

Business Focus

OKI has considerable experience designing equipment for professional and industrial environments.

Durability

The company emphasizes long-life designs and durable components.

Infrastructure Expertise

Unlike companies focused mainly on printing, OKI has extensive experience with telecommunications and infrastructure systems.

Japanese Manufacturing Heritage

The brand’s identity is strongly connected to Japanese engineering and electronics manufacturing.

The easiest way to understand OKI is to look at its history as a continuous technological progression:

Telecommunications → Electronics → Computing → Networking → Printing → Infrastructure → Edge/IoT → Integrated technology solutions

The underlying theme has remained relatively consistent: using electronics and communications technology to connect, monitor and support society. That explains why the same company can make a business printer, develop telecommunications infrastructure, manufacture electronic components, provide ATM technology and participate in advanced infrastructure projects.

OKI (Oki Electric Industry Co., Ltd.) is a Japanese technology company founded in 1881 by Kibataro Oki. Originally established as a telecommunications-equipment manufacturer, it became one of Japan’s long-standing electronics and information-technology companies, expanding into telephone systems, switching equipment, computers, semiconductors, ATMs, networking, printers, electronic components and manufacturing services. OKI became particularly well known internationally for its LED-based business printers and professional printing solutions, but its modern operations extend considerably beyond printing into social and network infrastructure, enterprise systems, defense, financial/payment solutions, components and EMS. Headquartered in Tokyo and listed on the Tokyo Stock Exchange, the company continues to operate globally under the OKI brand, whose current statement is “Open up your dreams.” 5
