By the late 1990s, Japan had already transformed the world of video games. Nintendo, Sega, Sony, Namco, Capcom, Square, Konami, and other Japanese companies had produced machines and games that were played across the world, while characters such as Mario had become international cultural icons. Yet inside universities, video games still occupied an uncertain position. They were commercially important and enormously popular, but they were not always treated as historical objects worthy of the same preservation and study given to books, films, paintings, or traditional art.
At Ritsumeikan University in Kyoto, Koichi Hosoi began confronting that problem directly.
Hosoi had joined Ritsumeikan in 1994 as a scholar of business administration. It was an unusually appropriate moment to begin thinking about games as an industry. Sega released the Saturn in Japan that year, Sony entered the console market with the PlayStation, and Nintendo’s dominance of the Japanese home console business faced a new kind of competition. Hosoi became interested in the industry’s economic and cultural importance, but turning that interest into serious academic research immediately exposed a problem.
There was little research material available.
Hosoi later recalled that he owned some games himself, but not enough to create a meaningful research collection. Attempts to purchase additional games with university research funds could be met with the objection that he was effectively asking the university to pay for toys. The situation captured one of the central problems facing early game scholars. Games were already a major cultural and commercial force, but the institutional structures needed to study them had barely begun to develop.
From that problem grew an archival project that would eventually become one of the most important institutional efforts to preserve the history of Japanese video games.
The Birth of the Game Archive Project
The institutional history of what became the Ritsumeikan Center for Game Studies does not begin with the center itself. RCGS was established in 2011, but its archival roots extend back to the Game Archive Project, generally known as GAP, which formally began in 1998. Contemporary and retrospective Ritsumeikan materials consistently identify 1998 as the beginning of the organized preservation effort.
Hosoi’s search for a way to conduct game research brought him into contact with Akimasa Yamashita of Kyoto Prefecture. Yamashita recognized something important about the geography of the Japanese video game industry. Kyoto was not simply an ancient capital known for temples, traditional arts, and cultural heritage. It was also the home of Nintendo and had become one of the centers from which modern Japanese game culture spread throughout the world.
Yamashita believed games could become another cultural bridge between Kyoto and an international audience. He suggested that Kyoto Prefecture could help establish cooperation between Ritsumeikan and Nintendo if the university became involved in game-related education and the development of people who might later work in the industry.
Hosoi and Yamashita began visiting Nintendo. Their discussions eventually reached Masayuki Uemura, then the head of Nintendo Research and Development 2 and one of the most important engineers in the history of home video games. Uemura had led the development of Nintendo’s Family Computer, better known outside Japan through its international counterpart, the Nintendo Entertainment System, and had also played a major role in the Super Famicom.
The proposal offered something useful to both sides. Ritsumeikan needed actual games and historical materials to create a serious field of study. Nintendo possessed years of material from its enormously successful console business that had not necessarily been organized as an academic archive. Uemura helped persuade Nintendo to cooperate.
Out of those discussions came the Game Archive Project, developed through cooperation among Ritsumeikan University, Kyoto Prefecture, Nintendo, and other partners. Hosoi was already describing himself as director of GAP in a December 1999 presentation on digital archives, only a short time after the project began.
Games were beginning to move from the living room shelf into the archive.
Nintendo’s 1,800 Famicom Games
Nintendo’s contribution gave the project something early game historians rarely possessed: a substantial body of original material.
With Uemura’s assistance, Nintendo allowed the Ritsumeikan team to work with approximately 1,800 pieces of Famicom software that had been stored by the company. Students and researchers began examining, identifying, organizing, and classifying the games.
That work was more complicated than simply placing cartridges on shelves.
Researchers examined packages, title screens, release information, manufacturers, copyright notices, and, when necessary, the ending credits of games themselves. The resulting information could then become part of a searchable body of metadata. A game was being treated not simply as something to play, but as an artifact that could be identified, cataloged, compared, and used as evidence.
Ritsumeikan eventually expanded beyond Nintendo. Hosoi later recalled organizing material associated with Sega and Sony as well, while archival research from the project records that Sega donated products over several years following the establishment of GAP.
The importance of this approach is easier to see in hindsight. The commercial life of a video game can be extremely short. A console disappears from stores, replacement hardware becomes difficult to find, packaging gets thrown away, magazines close, companies merge, websites vanish, and the people who created the games grow older. A title that seems ordinary while millions of copies are circulating can become surprisingly difficult to document decades later.
GAP was attempting to create historical infrastructure before much of that material disappeared.
Preserving More Than a Cartridge
From the beginning, the project faced a problem that separates video game preservation from many traditional archives. Owning the physical object does not necessarily preserve the experience.
A book can usually be opened and read centuries after it was printed if the paper survives. A cartridge cannot function independently. It depends on compatible hardware, controllers, displays, electrical standards, software environments, and sometimes networks or external services. Even perfectly preserved software can become inaccessible when the machine required to run it disappears.
Ritsumeikan researchers gradually developed a preservation philosophy built around multiple approaches rather than a single solution.
Physical preservation remained fundamental. Original consoles, software, accessories, printed materials, packaging, and related objects provided evidence that could not necessarily be recreated digitally. At the same time, researchers explored emulation as a way of preserving software after original hardware became obsolete.
By the early 2000s, GAP researchers were developing an authorized Famicom preservation emulator known as FDL. Research describing the project explained that emulator development began after researchers recognized that original physical equipment would eventually deteriorate. The goal was not simply to imitate how a Famicom game looked on a screen, but to develop a preservation system capable of reproducing the behavior of the original software across the wide variety of memory configurations used by Famicom games.
There was also a third problem. Even if the object survived and the program remained executable, would future historians know how people actually played it?
That question led researchers toward video documentation of gameplay. A video game is interactive. Its historical meaning exists partly in the relationship among the machine, the software, and the person holding the controller. Strategies, gestures, habits, mistakes, competition, and shared knowledge can all disappear even when the program itself survives.
Ritsumeikan’s preservation work increasingly reflected this broader idea. Preserving game history meant saving the software, the machinery, information surrounding the object, and evidence of play itself.
Games Enter the Museum
The Game Archive Project also helped bring video games into public historical exhibitions.
One important example was the Tokyo Metropolitan Museum of Photography’s exhibition “Level X,” organized to commemorate the twentieth anniversary of the Famicom. The exhibition was supported by a broad group of institutions and companies, with the Game Archive Project appearing among its supporting organizations and Nintendo participating as a special collaborator.
Ritsumeikan later described Level X as Japan’s first full-scale video game exhibition.
That mattered because an exhibition changes the context in which an object is encountered. The Famicom had originally been sold as consumer electronics and entertainment. Two decades later, it could appear inside a museum as an artifact through which visitors examined technology, design, industry, and popular culture.
The shift reflected the larger argument behind GAP. Games did not cease being entertainment when they entered an archive. Rather, their entertainment value was part of what made them historically important.
Masayuki Uemura Comes to Ritsumeikan
The relationship between Ritsumeikan and Masayuki Uemura eventually became much deeper than the original archival partnership.
After retiring from Nintendo, Uemura joined Ritsumeikan University in 2004. His arrival brought something especially valuable to an emerging academic field. Researchers like Hosoi could examine the video game industry from the perspective of economics, policy, culture, archives, and scholarship. Uemura could contribute the internal perspective of someone who had actually designed the technology that helped create the modern Japanese console industry.
Ritsumeikan later described the combination as bringing an “internal point of view” into a field that had largely approached the industry from outside.
Uemura participated in research on game preservation and the documentation of play while also teaching younger generations about games as designed experiences. By 2009, he was leading a seminar focused on the visualization of playing, extending the discussion beyond hardware engineering toward the difficult question of what happens between a game and its player.
His presence also connected an increasingly important part of Nintendo history directly with the development of Japanese game studies.
The Ritsumeikan Center for Game Studies
By the end of the 2000s, the work at Ritsumeikan had grown far beyond the original problem of organizing a collection of old games.
Researchers were studying preservation, industry history, game design, culture, technology, intellectual property, artificial intelligence, cognition, education, and the meaning of play itself. What began as a relatively unusual archival project was developing into a multidisciplinary field.
In April 2011, Ritsumeikan University established the Ritsumeikan Center for Game Studies within the Kinugasa Research Organization.
Masayuki Uemura became its first director.
RCGS was conceived as a cross-disciplinary institution rather than a center devoted only to electronic entertainment. Its stated research scope extended from traditional toys and forms of play to games using the newest technologies. Ritsumeikan also emphasized Kyoto’s special place within Japanese game history and positioned the center as a bridge connecting academic researchers, government institutions, public organizations, and the game industry.
The Game Archive Project did not disappear. Instead, its preservation activities became part of the archival research conducted through the new center.
The establishment of RCGS therefore represented less a beginning than an institutional recognition of work that had already been developing for more than a decade.
A Preservation Problem Bigger Than Ritsumeikan
Just before RCGS was established, Hosoi placed Ritsumeikan’s work within an increasingly urgent international discussion.
Writing in 2010 for the National Diet Library’s Current Awareness, he examined the problems confronting digital game archives around the world. Game preservation was becoming urgent because physical media deteriorated, hardware became obsolete, information disappeared, and software depended upon technologies that could quickly vanish.
These were no longer theoretical problems.
A functioning Famicom could fail. Magnetic and optical media could deteriorate. A game might depend upon a service that a company shut down. A digital storefront could disappear. An online game could effectively cease to exist when its servers were turned off.
Preservation therefore required cooperation among collectors, universities, museums, libraries, governments, developers, publishers, and researchers.
RCGS increasingly became part of that larger network.
Bringing the Preservation World to Kyoto
One of the clearest signs of Ritsumeikan’s growing international role came shortly after the center opened.
In January 2013, RCGS held an International Video Game Preservation Conference in Kyoto. Among the invited speakers were Henry Lowood of Stanford University, one of the leading figures in game and software preservation, and James Newman of Britain, who had been closely involved with the National Videogame Archive.
Hosoi and Uemura represented the Japanese preservation effort.
The event was deliberately international. RCGS framed video game preservation as a cultural problem shared across national boundaries and discussed the work being carried out through Japan’s Agency for Cultural Affairs. The center was increasingly connected not only to Japanese companies and government programs but to scholars and archival institutions attempting to answer similar preservation questions elsewhere in the world.
The archive that began with shelves of Japanese console software was becoming part of an international conversation about what should survive from the first generations of digital culture.
Replaying Japan Goes International
RCGS also became an important meeting point for scholars studying Japanese games.
During a visit to Ritsumeikan in 2011, University of Alberta professor Geoffrey Rockwell discussed with RCGS researchers a problem that had emerged within game studies. Scholars around the world were increasingly interested in Japanese video games, but much of the research produced in Japan remained separated from international scholarship by language and geography.
Those conversations led to a symposium at the University of Alberta in Edmonton in 2012 called Replaying Japan.
The response encouraged the organizers to expand the idea. In 2013, Ritsumeikan University hosted a full international conference devoted to Japanese game studies. The meeting became the foundation of an ongoing conference series.
Replaying Japan moved between institutions and countries. Later meetings were held at the University of Alberta, Ritsumeikan, Leipzig University in Germany, The Strong National Museum of Play in Rochester, New York, and the National Videogame Arcade in Nottingham, among other locations.
By the time the conference reached The Strong and Rochester Institute of Technology in 2017, nearly one hundred scholars were expected to participate, discussing Japanese video game culture, industry, education, history, and storytelling.
RCGS had helped create an international network around the study of the culture its archive had originally been built to preserve.
That international project eventually expanded into the journal Replaying Japan. The publication continues through RCGS, with Volume 8 issued in March 2026, demonstrating how an experimental collaboration that began with a symposium in Edmonton developed into a continuing academic institution.
Building the RCGS Collection
As the physical archive grew, another question became increasingly important. A collection is of limited scholarly value if researchers cannot determine what it contains.
The answer was cataloging.
Ritsumeikan began making bibliographic data available through RCGS-OPAC in 2017. In April 2019 the institution launched what became known as the RCGS Collection, an online catalog designed to allow researchers to search the center’s holdings.
This was more complicated than creating a list of game titles.
Video games present difficult cataloging problems because a single game may exist in multiple regional editions, platforms, packages, revisions, and formats. Researchers developed metadata structures informed by international cataloging approaches including Resource Description and Access and BIBFRAME, while also exploring Linked Open Data and connections with broader cultural databases.
The RCGS Collection was substantially updated again in September 2025, improving search functions while continuing to catalog physical game packages, related printed materials, consoles, and other devices. Its data also contributes to the Media Arts Database operated through Japan’s Agency for Cultural Affairs.
The archive had evolved from a collection into research infrastructure.
Thousands of Games and the Problem of Space
The scale of the collection illustrates how far the original project traveled.
Ritsumeikan reported that by February 2022 its archive had registered 11,283 software titles, 115 types of hardware, 200 types of peripherals, and approximately 8,000 types of related materials, excluding duplicates. Those related materials included objects such as magazines, advertisements, flyers, and soundtracks.
The physical objects were stored under carefully controlled environmental conditions intended to slow deterioration.
The success created another archival problem: space.
RCGS has acknowledged that storage limitations can restrict its ability to accept additional donations. That is a mundane problem compared with the theoretical questions surrounding emulation or metadata, but it reveals one of the unavoidable realities of preservation. Saving digital culture often requires preserving a surprising amount of physical material.
A complete history of gaming cannot be stored only on a hard drive.
Saving the Culture Around the Game
Perhaps the most important development in Ritsumeikan’s preservation philosophy has been the recognition that the software itself is only part of video game history.
Hosoi has compared the problem to preserving traditional performing arts. Historians attempting to understand an old performance may rely upon scripts, images, guidebooks, reviews, songs, and other records surrounding an event that can never be perfectly recreated.
Games present a similar challenge.
Future researchers trying to understand a major game may need the cartridge, console, manual, strategy guide, advertising, magazine coverage, developer testimony, fan publications, recorded gameplay, and memories of the people who created and played it.
RCGS has therefore extended its work into areas such as exhibitions and oral history. The center participates in a collaborative oral history project with researchers connected to Hitotsubashi University, the University of Tsukuba, and Waseda University, preserving testimony from people involved in Japan’s game industry.
This is especially important because games are still young enough that many of the people who created their formative periods can be interviewed directly.
That opportunity will not last forever.
From Toys to Historical Evidence
The history of the Ritsumeikan Center for Game Studies can be understood through a striking change in perspective.
When Koichi Hosoi first tried to build a research collection, video games could still be dismissed within an academic environment as toys that did not belong in a university research budget.
A generation later, Ritsumeikan maintains thousands of pieces of game software and related materials, develops sophisticated cataloging systems, conducts archival research, records oral histories, organizes international conferences, publishes scholarship, works with government preservation programs, and collaborates with institutions around the world.
The objects did not change.
The historical questions surrounding them did.
A Famicom cartridge once purchased by a child in the 1980s can now provide evidence about industrial design, software development, advertising, copyright, popular art, Japanese business, technological change, international trade, childhood, music, storytelling, and the everyday culture of an entire generation.
The same transformation is occurring with newer games. Today’s ordinary entertainment becomes tomorrow’s primary source.
Why Ritsumeikan Matters to Video Game History
The importance of Ritsumeikan’s work lies partly in timing.
The Game Archive Project began in 1998, when the commercial video game industry was already several decades old but institutional preservation remained comparatively undeveloped. Ritsumeikan entered the field early enough to work directly with Nintendo and other companies while material from important periods of Japanese game history still survived in corporate collections and while many of the people responsible for creating those games were still available to explain them.
Masayuki Uemura provided a direct bridge between the engineering history of Nintendo and the academic study of games. Koichi Hosoi pushed for games to be treated as cultural and historical resources. Students and researchers performed the less glamorous but essential work of identifying, cataloging, testing, documenting, and preserving thousands of objects.
RCGS then expanded those efforts into government projects, international conferences, scholarly publications, metadata research, online catalogs, exhibitions, and oral histories.
What began with the problem of how a professor could obtain enough games to study became something much larger.
It became an attempt to answer one of the central questions facing video game historians: what must be saved so that people fifty or one hundred years from now can understand what playing a video game meant?
Ritsumeikan’s answer has steadily become broader. Save the cartridge. Save the machine. Preserve the software. Record the gameplay. Catalog the package. Keep the advertisement and magazine. Interview the developer. Document the player. Connect the archive to other archives.
Then make it possible for future researchers to find all of it.
That philosophy has made the Game Archive Project and the Ritsumeikan Center for Game Studies an important part of video game history themselves.
