Nintendo Co., Ltd. (任天堂株式会社, Nintendō Kabushiki Gaisha) is a Japanese multinational video game company headquartered in Kyoto, Japan. It develops, publishes and releases both video games and video game consoles.

Nintendo was founded as Nintendo Koppai on 23 September 1889 by craftsman Fusajiro Yamauchi in Shimogyō-ku, Kyoto, Japan, as an unincorporated establishment, to produce and distribute Japanese playing cards, or karuta (かるた, from Portuguese carta, 'card'), most notably hanafuda (花札, 'flower cards'). The name "Nintendo" is commonly assumed to mean "leave luck to heaven", but the assumption lacks historical validation; it can alternatively be translated as "the temple of free hanafuda". Hanafuda cards had become popular after Japan banned most forms of gambling in 1882, though tolerated hanafuda. Sales of hanafuda cards were popular with the yakuza-ran gaming parlors in Kyoto. Other card manufacturers had opted to leave the market not wanting to be associated with criminal ties, but Yamauchi persisted without such fears to become the primary producer of hanafuda within a few years.

Japanese culture stipulated that for Nintendo to continue as a family business after Yamauchi's retirement, Yamauchi had to adopt his son-in-law so that he could take over the business. As a result, Sekiryo Kaneda adopted the Yamauchi surname in 1907 and headed the business in 1929. By that time, Nintendo was the largest playing card business in Japan.

In 1933, Sekiryo Kaneda established the company as a general partnership named Yamauchi Nintendo & Co., Ltd. investing in the construction of a new corporate headquarters located next to the original building, near the Toba-kaidō train station. Because Sekiryo's marriage to Yamauchi's daughter produced no male heirs, he planned to adopt his son-in-law Shikanojo Inaba, an artist in the company's employ and the father of his grandson Hiroshi, born in 1927. However, Inaba abandoned his family and the company, so Hiroshi was made Sekiryo's eventual successor.

In 1947, Sekiryo founded the distribution company Marufuku Co., Ltd. responsible for Nintendo's sales and marketing operations, which would eventually go on to become the present-day Nintendo Co., Ltd., in Higashikawara-cho, Imagumano, Higashiyama-ku, Kyoto.

In 1950, due to Sekiryo's deteriorating health, Hiroshi Yamauchi assumed the presidency and headed manufacturing operations. His first actions involved several important changes in the operation of the company: in 1951, he changed the company name to Nintendo Playing Card Co., Ltd. and in the following year, he centralized the manufacturing facilities dispersed in Kyoto, which led to the expansion of the offices in Kamitakamatsu-cho, Fukuine, Higashiyama-ku, Kyoto. In 1953, Nintendo became the first company to succeed in mass-producing plastic playing cards in Japan.

In 1959, Nintendo moved its headquarters to Kamitakamatsu-cho, Fukuine, Higashiyama-ku, Kyoto. The company entered into a partnership with The Walt Disney Company to incorporate its characters into playing cards, which opened it up to the children's market and resulted in a boost to Nintendo's playing card business. Nintendo automated the production of Japanese playing cards using backing paper, and also developed distribution system that allowed it to offer its products in toy stores. By 1961, the company had established a Tokyo branch in Chiyoda, Tokyo, and sold more than 1.5 million card packs, holding a high market share, for which it relied on televised advertising campaigns. In 1962, Nintendo became a public company by listing stock on the second section of the Osaka Securities Exchange and on the Kyoto Stock Exchange. In the following year, the company adopted its current name, Nintendo & Co., Ltd. and started manufacturing games in addition to playing cards.

In 1964, Nintendo earned ¥150 million. Although the company was experiencing a period of economic prosperity, the Disney cards and derived products made it dependent on the children's market. The situation was exacerbated by the falling sales of its adult-oriented playing cards caused by Japanese society gravitating toward other hobbies such as pachinko, bowling, and nightly outings. When Disney card sales began to decline, Nintendo realized that it had no real alternative to alleviate the situation.

In 1965, Nintendo hired Gunpei Yokoi to maintain the assembly-line machines used to manufacture its playing cards. Yamauchi's experience with the previous initiatives led him to increase Nintendo's investment in a research and development department in 1969, directed by Hiroshi Imanishi, a long-time employee of the company. Yokoi was moved to the newly created department and was responsible for coordinating various projects. Yokoi's experience in manufacturing electronic devices led Yamauchi to put him in charge of the company's games department, and his products would be mass-produced. During this period, Nintendo built a new production plant in Uji, just outside of Kyoto, and distributed classic tabletop games such as chess, shogi, go, and mahjong, and other foreign games under the Nippon Game brand. The company's restructuring preserved a couple of areas dedicated to playing card manufacturing.

The year 1970 represented a watershed moment in Nintendo's history as it released Japan's first electronic toy—the Beam Gun, an optoelectronic pistol designed by Masayuki Uemura. In total, more than a million units were sold. Nintendo partnered with Magnavox to provide a light gun controller based on the Beam Gun design for the company's new home video game console, the Magnavox Odyssey, in 1971. Other popular toys released at the time include the Ultra Hand, the Ultra Machine, the Ultra Scope, and the Love Tester, all designed by Yokoi. More than 1.2 million units of Ultra Hand were sold in Japan.

Yokoi, Uemura, and new employees such as Genyo Takeda, continued to develop innovative products for the company. The Laser Clay Shooting System was released in 1973 and managed to surpass bowling in popularity.

In 1974, Nintendo released Wild Gunman, a skeet shooting arcade simulation consisting of a 16 mm image projector with a sensor that detects a beam from the player's light gun. Both the Laser Clay Shooting System and Wild Gunman were successfully exported to Europe and North America. However, Nintendo's production speeds were still slow compared to rival companies such as Bandai and Tomy, and their prices were high, which led to the discontinuation of some of their light gun products. The subsidiary Nintendo Leisure System Co., Ltd., which developed these products, was closed as a result of the economic impact dealt by the 1973 oil crisis.

Yamauchi, motivated by the successes of Atari and Magnavox with their video game consoles, acquired the Japanese distribution rights for the Magnavox Odyssey in 1974, and reached an agreement with Mitsubishi Electric to develop similar products between 1975 and 1978, including the first microprocessor for video games systems, the Color TV-Game series, and an arcade game inspired by Othello. During this period, Takeda developed the video game EVR Race, and Shigeru Miyamoto joined Yokoi's team with the responsibility of designing the casing for the Color TV-Game consoles. In 1978, Nintendo's research and development department was split into two facilities, Nintendo Research & Development 1 and Nintendo Research & Development 2, respectively managed by Yokoi and Uemura.

Two key events in Nintendo's history occurred in 1979: its American subsidiary was opened in New York City, and a new department focused on arcade game development was created.

Nintendo entered the arcade video game market with Sheriff and Radar Scope, released in Japan in 1979 and 1980 respectively. Sheriff, also known as Bandido in some regions, marked the first original video game made by Nintendo, was published by Sega and developed by Genyo Takeda and Shigeru Miyamoto.

While Radar Scope, rivaled Galaxian in Japanese arcades but failed to find an audience overseas and created a financial crisis for the company. To try to find a more successful game, they put Miyamoto in charge of their next arcade game design, leading to the release of Donkey Kong in 1981, one of the first platform video games that allowed the player character to jump. The character, Jumpman, would later become Mario and Nintendo's official mascot. Mario was named after Mario Segale, the landlord of Nintendo's offices in Tukwila, Washington. Donkey Kong was a financial success for Nintendo both in Japan and overseas.

The first issue of Nintendo Power magazine, which had an annual circulation of 1.5 million copies in the United States, was published in 1988.

In July 1989, Nintendo held the first Nintendo Space World trade show with the name Shoshinkai for the purpose of announcing and demonstrating upcoming Nintendo products. That year, the first World of Nintendo stores-within-a-store, which carried official Nintendo merchandise, were opened in the United States.

In March 1990, the first Nintendo World Championship was held, with participants from 29 American cities competing for the title of "best Nintendo player in the world".

In June 1990, the subsidiary Nintendo of Europe was opened in Großostheim, Germany; in 1993, subsequent subsidiaries were established in the Netherlands (where Bandai had previously distributed Nintendo's products), France, the United Kingdom, Spain, Belgium, and Australia.

Nintendo ceased manufacturing arcade games and systems in September 1992.

The proliferation of graphically violent video games, such as Mortal Kombat, caused controversy and led to the creation of the Interactive Digital Software Association and the Entertainment Software Rating Board, in whose development Nintendo collaborated during 1994.

In 2014, a new product line was released consisting of figures of Nintendo characters called amiibos.

On 25 September 2013, Nintendo announced its acquisition of a 28% stake in PUX Corporation, a subsidiary of Panasonic, for the purpose of developing facial, voice, and text recognition for its video games.

On 11 July 2015, Iwata died of bile duct cancer, and after a couple of months in which Miyamoto and Takeda jointly operated the company, Tatsumi Kimishima was named as Iwata's successor on 16 September 2015. As part of the management's restructuring, Miyamoto and Takeda were respectively named creative and technological advisors.

In March 2016, Nintendo's first mobile app for the iOS and Android systems, Miitomo, was released. Since then, Nintendo has produced other similar apps, such as Super Mario Run, Fire Emblem Heroes, Animal Crossing: Pocket Camp, Mario Kart Tour, and Pokémon Go, the last being developed by Niantic and having generated $115 million in revenue for Nintendo. In March 2016, the loyalty program My Nintendo replaced Club Nintendo.

In 2018, Shuntaro Furukawa replaced Kimishima as company president, and in 2019, Doug Bowser succeeded Nintendo of America president Reggie Fils-Aimé. In April 2019, Nintendo formed an alliance with Tencent to distribute the Nintendo Switch in China starting in December.

The year 2020 saw some changes to the company's management: outside director Naoki Mizutani retired from the board, and was replaced by Asa Shinkawa; and Yoshiaki Koizumi was promoted to senior executive officer, maintaining its role as deputy general manager of Nintendo EPD. By August, Nintendo was named the richest company in Japan.

In June 2021, the company announced plans to convert its former Uji Ogura plant, where it had manufactured playing and hanafuda cards, into a museum tentatively named "Nintendo Gallery", targeted to open by March 2024. In the following year, historic remains of a Yayoi period village were discovered in the construction site.

The theme park area Super Nintendo World opened at Universal Studios Japan in 2021.

In 2021, Furukawa indicated Nintendo's plan to create more animated projects based on their work, and by 29 June, Meledandri joined the board of directors as a non-executive outside director.

In February 2022, Nintendo announced the acquisition of SRD Co., Ltd. (Systems Research and Development) after 40 years, a major contributor of Nintendo's first-party games such as Donkey Kong and The Legend of Zelda until the 1990s, and then support studio since.

In early 2023, the Super Nintendo World theme park area in Universal Studios Hollywood opened.

Nintendo co-produced an animated film The Super Mario Bros. Movie alongside Universal Pictures and Illumination, with Miyamoto and Illumination CEO Chris Meledandri acting as producers. The Super Mario Bros. Movie was released on 5 April 2023, and has grossed over $1.3 billion worldwide, setting box-office records for the biggest worldwide opening weekend for an animated film, the highest-grossing film based on a video game and the 15th-highest-grossing film of all-time.
