Irem (アイレム Airemu) is a Japanese video game console developer and publisher, and formerly a developer and manufacturer of arcade games as well. The company has its headquarters in Hakusan, Ishikawa Prefecture.[1]

The company is probably best known for Moon Patrol, the famous scrolling shooter R-Type and the earliest beat 'em up, Kung-Fu Master. They have been a popular developer in Japan with games like Photoboy for the PC Engine and In the Hunt for the arcades, Sega Saturn, PlayStation, and PC. Irem is also known for making their arcade games extremely difficult, and most of them feature a dip switch that allows you to play a "no death mode" as a result, in order to allow gamers to be able to complete their tough games.

As a result of the 2011 Tōhoku earthquake and tsunami, Irem canceled the majority of its remaining video game projects, including Zettai Zetsumei Toshi 4: Summer Memories and Poncotsu Roman Daikatsugeki Bumpy Trot 2.[2] Irem re-focused to become primarily a slot-machine and pachinko developer, the industry it was in before turning to video games. Its video game division was dissolved in April 2011 and many Irem designers, including producer Kazuma Kujo, gathered to form a new company called Granzella to continue creating games.[2]

Irem was founded in 1974 under the name IPM, an abbreviation for International Playing Machine. Its purpose was to manufacture, sell, and rent arcade hardware cabinets. IPM released its first video arcade games in 1978, starting with their first arcade game, IPM Invader. In 1979, IPM changed its name to Irem Corporation. Originally an abbreviation for "International Rental Electronics Machines", the meaning of Irem's acronym was changed to "Innovations in Recreational Electronic Media" in the first half of the 1980s.

As Irem entered the 1990s, their logo included a dragonfly because in Japan, dragonflies symbolize "martial success," due to similarity in the sound of the word "dragonfly" and "victory" in Japanese. However, shortly after that, the corporation began to decline. Sales were so poor that in 1994, Irem completely ceased development of video games. The company's original wholesale division, which was in charge of manufacturing and renting/selling arcade cabinets, spun off from Irem to form its own company called Apies (アピエス Apiesu); leaving Irem with only the video game division. Then a group of employees, tired of the company's inactivity, left Irem to form their own company under the name Nazca Corporation, which became best known for developing SNK's Metal Slug franchise.

On April 15, 1997, Nanao (now Eizo Corporation) founded Irem Software Engineering Inc. Shortly after in July 1997, Irem Software Engineering took over the development department of Irem Corporation and absorbed it. The publishing department of Irem Corporation, on the other hand, became under the direct control of Nanao who then sold it to none other than Apies in 1998.

Irem now develops and publishes games in Japan exclusively for the PlayStation 2, the PlayStation 3 and the PlayStation Portable. Overall, the video game development department is the only remnant of the former Irem Corporation which is still associated with the brand.

Irem Software Engineering is headquartered in Hakusan. It is a wholly owned subsidiary of Eizo Corporation.

PlayStation Home

Irem released a promotional space in the Asian and Japanese versions of PlayStation Home, the PlayStation 3's online community-based service. The space is called the "Irem Square". This space features various "Night Stalls" with free items such as a yukata and was released on February 26, 2009 in the Japanese version. Users can also access the game space for Minna de Spelunker from this space. On April 1, 2009, Irem gave away free "Combatant of the Black Irem Brigade" suits in the space that were only available for that day.[3] There is also a store in the space that users can purchase items from Irem. This space was released in the Asian Home on July 16, 2009, but the only way users could access it, at the time, was by riding in the space ship that was accessed at the "Bus Stop" in the Home Square. The ship departed every fifteen minutes and after landing, users got a hat that is modeled after the ship. The space was added to Asia's world map on July 23, 2009. On August 13, 2009, Irem added another space called the "Seaside of Memories", which is a beach resort with three accessible huts. The first hut has a shop for swimsuit apparel and the other two are just for users to sit and chat. This is also the first Home Space to let users go in and under the water and if they stay under the water too long, they get sent back to the entrance of the space. On December 3, 2009, Irem released another space to Japan for their game R-Type Tactics II: Operation Bitter Chocolate called the Sparkling Flash Space, which is based in space and features displays of three R-Type Shooters and a mini-game.[4] During the holiday season in Home, Irem redecorated their spaces for the occasion. Irem redecorated the spaces, except the Sparkling Flash Space, for Christmas from December 17, 2009 until January 7, 2010. They were decorated for the New Year (2010) from January 7, 2010 to January 14, 2010 in Japan and from January 7, 2010 to January 21, 2010 in Asia. From January 28, 2010 to February 18, 2010, there was an event going on, in collaboration between Irem, Nippon Ichi Software, and Sony Computer Entertainment, in Asia called the "Black Irem Brigade". Irem Square is also available in the North American PlayStation Home.[5]

Virtual Console

Until November 2011, various Irem games including the R-Type series were available on the Wii's Virtual Console service. That month, Irem began its removal of all games from the service, with all of them being gone by the end of March 2012. All Irem games for the Turbografx-16 were also returned into the service on mid-September 2013.
