IPSJ Computer Museum is a virtual museum where you can find information about historical Japanese computers and the people engaged in the development of those computers. Half a century has passed since the development of Japan’s first electronic computers, FUJIC and ETL Mark III in 1956. Explanations and photos of computers developed during this period and related many materials are displayed at this museum.
It is said, “If you want to know what's to come, look into the
past.” We are very happy if these historical materials can give
you hints for the future..
For more information regarding the founding of this museum, please refer
to the message from Takahashi Shigeru, the first chairman
of Special Committee for the History of Computing.

Special Committee of the History of Computing
set up by Information Processing Society of Japan (IPSJ) in 1981
published two books: "History of Japanese Computers" (1985,
Ohm-Sha, Tokyo) and "History of Japanese Computer Development" (1998,
Ohm -Sha, Tokyo). The former tells history before 1960 and the
latter from 1961 to 1980. Recently, we have helped IPSJ Magazine
to publish historical articles in series or in a special issue.
the other hand, the recent rapid technological progress has brought
into existence open systems,
downsizing of computer systems, and wide use of computer networks
such as Internet, all of which have caused the drastic change of
information technology and computer industry after 1990s.
as well as peripheral equipments produced before1990 are quickly
vanishing, and it is now getting more and more difficult
to see them as real objects. Input and output media such as paper
tape and card and storage media such as disk pack are also disappearing.
view of passing historical facts of Information technology to coming
generations, it is not sufficient only to write about them
in books or magazines. It would
be more desirable for some organization to collect and keep them as real objects
together with relevant materials.
In foreign countries, particularly in U.S.,
exist several museums for computers, in which historical computers
and related objects have been carefully kept and
displayed. In Japan, we have no museum dedicated for computers, though the National
Science Museum plays a part of such a role.
In 2001, the National Science Museum
held a special exhibition, "Leaders in the Information Century" and
IPSJ held an exhibition, "Epochs in Information Technology," in the
occasion of the 40th anniversary of its founding. However, these were only
temporary exhibitions. Since it is difficult for an academic society
such as IPSJ to collect and keep real objects, we decided to limit
ourselves to cooperation with the
Science Museum as for real objects. Instead, we have set up a virtual Computer
Museum in IPSJ’s web pages to collect and keep valuable historic information
in a way more appropriate to IPSJ.
Here, we show photographs of historic computers
and parts with their explanations relative to the time line of technological
We are very much indebted to those who provided
us with photographs and explanations.
