It was a university-origin venture founded by Shota Hattori, who was involved in structural design research as an assistant in the laboratory of Professor Tadashi Taniguchi at the Department of Architecture, Tokyo Institute of Technology. Starting with a drawing board in his home reception room at 1-768 Kamiozaki, Shinagawa-ku, Tokyo, with Hattori himself and one other person, a total of two, the company grew to about ten in two years, then expanded by leasing a house next door to his home for an office. |

Founded the Masaru Hattori Structural Planning Institute. It is a university-originated venture company founded by Masaru Hattori, who was involved in structural design as an assistant in the laboratory of Professor Tadashi Taniguchi of the Department of Architecture, Tokyo Institute of Technology. Started with a drawing board brought into the home reception room at 1-768 Kamiosaki, Shinagawa-ku, Tokyo, with Masaru Hattori himself and one other person, totaling two. After increasing to about ten in two years, the office was expanded by renting the house next door. |

We aim to serve as a bridge to return university research results to society. Under this philosophy, we established Kozogaku Planning Research Institute Inc. Shortly after founding, Hattori noticed an article about structural calculations using computers published in an academic journal in the United States, which sparked his dream of computers, leading him to travel to the U.S. |

Established Structural Planning Institute Inc. Aiming to give back academic research results to society, the company was founded. Soon after its founding, Masaru Hattori, who read an article about structural calculations using computers published in a conference journal in the United States, recognized its great potential and traveled to the U.S. |

From the late 1950s to the early 1960s, a reconstruction boom of castle keeps swept across Japan as a symbol of postwar reconstruction. Under the guidance of Professor Michio Fujioka, a specialist in Japanese architectural history, he was involved in structural design for many castles including Wakayama Castle, Kumamoto Castle, and Odawara Castle, contributing to castle reconstruction nationwide. Castle restoration involved working amidst cultural assets like stone walls and moats that required careful preservation, demanding complex, specialized skills and high technical ability. |
| 1960 |
Supporting Kei Ando, who transferred from IBM Japan to Fujitsu, and supporting the development of Fujitsu's FACOM series, a pioneer of domestic computers, Hattori also supported the development of operating systems (OS) with Toshiro Ikeda, a university senior. In 1969, they introduced the FACOM 230/60 within the company, contributing to the development of domestic computers. |
| 1960 |
Boom in the reconstruction of castle keeps. As symbols of post-war reconstruction, a boom in rebuilding castle keeps swept across Japan. Designed structures for Wakayama Castle, Kumamoto Castle, Odawara Castle, and others, involved in castle reconstruction nationwide. |
| 1961 |
With the dream and mission to eliminate the busyness of structural design work and focus on more valuable tasks, Hattori traveled alone to the University of Illinois to Professor Newmark in 1960. Upon returning, he pioneered the industry's first digital computer, IBM 1620. The rental fee was 600,000 yen per month, at a time when the starting salary was 12,000 yen. Handling expensive computers required fire insurance, leading to the relocation of the headquarters from a wooden building to a reinforced concrete building in Taito-ku, Torigoe. |
| 1961 |
Introduction of IBM 1620. Masaru Hattori went to the U.S. in 1960 and immediately after returning, realized the introduction of the latest digital computer IBM 1620. The rental fee alone was 600,000 yen per month, and the headquarters was relocated to a reinforced concrete building for fire insurance. |
| 1964 |
With the introduction of IBM 1620-II, the company moved to the 'Japan Holstein Hall,' which was responsible for structural design, as a space suitable for installing computers. |
| 1964 |
Relocated the head office to Holstein Hall in Nakano Ward, Tokyo. Moved in conjunction with the introduction of IBM 1620-II, providing space for the computer. |
| 1967 |
We have developed a three-dimensional frame structure analysis software "STAN" used for structural design and analysis consulting work, utilizing large-scale computers introduced. We continue to improve and develop the software to match the times, which has led to the development and sale of current PC software packages. |
| 1967 |
Development of the "STAN" structural analysis software. Developed a three-dimensional frame structure analysis software "STAN" for structural design and analysis consulting work, using the introduced large-scale computer. |
| 1969 |
To expand the sales of our self-developed software "STAN" in the United States and gather the latest information, we participated financially in San Francisco's International Logic Cooperation "ILC". At the same time, we started contract software development. There are reports in newspapers at the time that it was "noted as opening the way for the export of intangible products that sell brains." It was a challenge in the United States, where the software market in Japan was not yet mature. |
| 1969 |
Established ILC in the U.S. To expand sales of our self-developed software "STAN" in the U.S. and gather information, we participated financially in San Francisco's International Logic Cooperation "ILC". At the same time, we started contract software development. |
| 1970 |
In the 1970s, small mini computers that could be handled by laboratories and small and medium-sized enterprises appeared, replacing large mainframe computers occupying floors of buildings. Recognizing the potential of this computer, Masaru Hattori, along with Morihiko Hiramatsu (later governor of Oita Prefecture), who was then the director of the Information Processing Promotion Division of the Ministry of International Trade and Industry, established Japan Mini Computer Co., Ltd., a government-affiliated company. The mission stated in the establishment document at that time was "to develop and manufacture Mini Computers as components that realize their needs as much as possible, together with like-minded people, and to contribute to each company's original work with confidence, which is the mission and aspiration of the new company." |
| 1970 |
Established Japan Mini Computer (later Japan Data General). With the advent of small mini computers, established Japan Mini Computer Co., Ltd., a government-affiliated company. |
| 1972 |
Establishment of Japan Software Industry. Aiming to establish software technology, led industry development as chairman of the Japan Software Industry Promotion Association. |
| 1974 |
In 1974, our company's Operations Research (OR) laboratory was established. Although initially engaged in structural design, Masaru Hattori always had a strong desire to "create an organization of engineers with diverse expertise capable of addressing any social problem." In 1963, he attended the International OR Society meeting held in Oslo, Norway, as Japan's representative along with Professor Takehiko Matsuda of Tokyo Institute of Technology. From early on, he was considering challenging fields beyond structural design using computers. |
| 1974 |
