Gunpei Yokoi

Gunpei Yokoi (September 10, 1941 - October 4, 1997) was a Japanese engineer and toy and video game hardware designer who worked at Nintendo from 1965 to 1996. He headed the company's first research and development department and is best known for the Game & Watch handhelds and the Game Boy. He also led development of the Virtual Boy (1995), a tabletop stereoscopic game console built around a red LED display licensed from the American company Reflection Technology. Yokoi first conceived it as a pair of head-worn goggles with head tracking, in the virtual reality wave of the early 1990s, before safety and weight concerns turned it into a viewer on a bipod stand.

The Virtual Boy sold poorly and was withdrawn in Japan within six months of its launch. Yokoi left Nintendo in August 1996, founded Koto Laboratory, and was killed in a traffic accident on October 4, 1997, at the age of 56. He received the Game Developers Choice Awards' Lifetime Achievement Award posthumously in 2003.

Early life and education

Yokoi was born on September 10, 1941, and was raised in Kyoto. He earned a degree in electronics from Doshisha University.

Career

Toys and handheld games at Nintendo

Nintendo, then a Kyoto playing card maker, hired Yokoi in 1965 to maintain the assembly line machines that made its cards. As imported cards cut into the business, president Hiroshi Yamauchi diversified the company, and around 1970 he asked Yokoi to make something Nintendo could sell that Christmas. Yokoi had built a wooden extending grabber for his own amusement; as the Ultra Hand it became Nintendo's first toy and sold 1.2 million units, according to David Sheff's book Game Over. Later hits included a "love tester" and the "laser clay range", which turned disused bowling alleys into shooting galleries where players fired light-beam guns at clay pigeons.

When Nintendo moved into electronic games it was divided into three competing research and development departments. Yokoi headed department No. 1 (R&D1), which concentrated on small handheld games rather than home consoles. His first handheld was the Game & Watch, released in 1980, a calculator-sized device with a simple game on a liquid crystal screen and a clock in the corner. The line introduced the cross-shaped directional pad that became standard on Nintendo controllers. His contributions also included R.O.B., the robot accessory bundled with the Nintendo Entertainment System Deluxe Set in 1985. The Game & Watch led to the Game Boy (1989), a handheld that played games stored on cartridges; by the time of Yokoi's death about 55 million had been sold. The Game Boy used an inexpensive monochrome LCD without a backlight at a time when competitors were building handhelds with backlit color screens.

Yokoi called his approach "lateral thinking with withered technology": building products from mature, cheap and well-understood components used in new ways, with an emphasis on low cost, battery life and play rather than leading-edge specifications.

Virtual Boy

In 1991 Reflection Technology, a company formed in 1986 by engineer Allen Becker and colleagues, visited Nintendo in Kyoto to demonstrate its Private Eye display. The display swept the reflection of a single line of red LEDs across the eye with a mirror that oscillated 50 times a second, forming a sharp, bright image. Reflection had built a demonstration headset from two Private Eye units mounted on a welder's mask, with a simple head-tracking device and a tank game running on a PC; Mattel, Hasbro and Sega had already turned the technology down. Reflection's chief scientist, Benjamin Wells, later recalled that Yokoi "fell in love with the technology" and pushed for it inside Nintendo.

Where others saw a limitation in the red-on-black display, Yokoi saw a way to show complete blackness. In his 1997 book written with author Takefumi Makino, he wrote that LCDs need backlighting that lets some light seep through even in darkness, while unlit LEDs do not, and that "the idea was to have it be in total darkness, so you would not feel the frame of the screen." Questioning Nintendo's future if it kept making video games the same way, he wrote: "If the TV screen medium has reached the limits of its potential, isn't 3D the only option?" The 2024 MIT Press study Seeing Red: Nintendo's Virtual Boy by José P. Zagal and Benj Edwards likewise describes Yokoi as drawn to the display's ability to simulate absolute blackness, which he saw as a way to make the system distinct from other game platforms. According to Edwards, Yokoi had planned to retire from Nintendo at 50 and start his own company, and the project put those plans on hold.

Nintendo bought a worldwide exclusive license to the display for video games, paying US$10 million in advance royalties, and took a minority stake in Reflection Technology. Mitsumi built the display assemblies. Development, code-named VR32, began with a wearable device as the goal. Makino has said that "Yokoi's first intention was to create a game console that looked like a pair of goggles," one that players could put on and walk around in. Engineers worried about placing a chip with high radio emissions next to the user's head, and the metal shielding that the processor then needed made the goggles too heavy. A heavier version propped against the face with a shoulder stand followed, but Nintendo's legal department feared injuries such as children falling down stairs while wearing it, and the design became a tabletop viewer on a bipod. Under Yokoi's direction the engineers used a low-power 32-bit RISC processor from NEC with custom graphics chips.

At Reflection's suggestion, Nintendo commissioned Eli Peli of the Schepens Eye Research Institute in Boston to study the display's effect on vision. According to Wells, the study found it generally harmless, with one caveat about young children if the two displays were vertically misaligned, so the displays were mounted in a rigid case and steel frame. Japan's Product Liability Act, which took effect on July 1, 1995, led Nintendo to add prominent health warnings and an in-game reminder to rest every 15 minutes. Yokoi later wrote that buyers who did not know about the law "got the image that this product was bad for your health." Nintendo first showed the Virtual Boy publicly on November 15, 1994, at its Shoshinkai exhibition in Japan, and at the Winter Consumer Electronics Show (CES) in Las Vegas on January 6, 1995.

The console launched in Japan on July 21, 1995, and in North America in August 1995 at US$179.95. By December 1995 it had sold only 140,000 units in Japan, and Yamauchi ended it there on December 22, 1995. Nintendo of America cut the price to US$99 in May 1996 and dropped the system that August. Worldwide sales were reported at roughly 770,000 units. Yokoi blamed press coverage, the misunderstanding of hardcore players, the form factor and above all weak marketing in Japan; Makino said that what Yokoi most regretted was not having managed to create a new kind of video game. Howard Lincoln, chairman of Nintendo of America, told the New York Times that Yokoi "took it quite personally when it was not successful."

Departure from Nintendo and Koto Laboratory

After the Virtual Boy, Yokoi's group produced the Game Boy Pocket, a smaller, lighter version of the Game Boy released in 1996. Yokoi resigned on August 16, 1996, after nearly 31 years at the company. Because Japanese executives usually stayed with one company for life, his departure fed speculation that Nintendo was in trouble and contributed to a run on its stock, although the main cause of that day's selling was a newspaper report that profits would fall. American and Japanese press linked his exit to the Virtual Boy's failure. Makino has said Yokoi was very troubled by these reports, which he called misunderstandings, and Edwards writes that Yokoi had planned to leave Nintendo all along; according to Makino, Yokoi's plan had been for the Virtual Boy to succeed and for Nintendo's products to be organized into consoles, mobile devices and wearables before he left. The 2024 book Seeing Red also disputes the idea that the console's failure caused his exit.

About a month after leaving, Yokoi founded Koto Laboratory in Kyoto with Yoshihiro Taki, a former R&D1 colleague. The company worked on LCD keychain games and a monochrome handheld console that ran on a single AA battery, which was later sold to Bandai and released in Japan as the WonderSwan. Lincoln said Yokoi kept a close relationship with Nintendo.

Death

On October 4, 1997, Yokoi was a passenger in a car that struck a truck from behind on an expressway in Ishikawa Prefecture. When he and the driver got out to inspect the damage, another car hit them, killing Yokoi and injuring the driver. He was 56. The Escapist identifies the road as the Hokuriku Expressway.

Legacy

At the Game Developers Choice Awards, held during the Game Developers Conference on March 6, 2003, Yokoi received the Lifetime Achievement Award posthumously. Sega's Yuji Naka presented it, and members of Yokoi's family accepted it.

Benj Edwards writes that the Private Eye display, originally pitched as a hands-free head-mounted display for tasks such as surgery and aircraft maintenance, helped start the concepts of wearable computing and augmented reality, and that it reached only two consumer products, the Virtual Boy and Reflection's FaxView. He also notes that, despite its name, the Virtual Boy was not virtual reality in the immersive sense, because 1995 technology could not generate immersive worlds; he describes it as the first and only natively stereoscopic video game system. In September 2025 Nintendo announced Virtual Boy - Nintendo Classics, a collection of Virtual Boy games for Nintendo Switch Online + Expansion Pack members in the United States and Canada, played through a replica Virtual Boy accessory (US$99.99) or a cardboard model (US$24.99). The collection launched on February 17, 2026.
