Ken Kutaragi (久夛良木 健, Kutaragi Ken^?, born August 8, 1950) is the former Chairman and chief executive officer of Sony Computer Entertainment (SCEI), the video game division of Sony Corporation. He is known as "The Father of the PlayStation", and its successors and spinoffs, including the PlayStation 2, PlayStation Portable, and the PlayStation 3.

Before this time, he had designed the sound processor for the Super Nintendo. With Sony, he designed the VLSI chip which works in conjunction with the PS1's RISC CPU to handle the 3D rendering.

Kutaragi was closely watched by financial analysts who trace profiles of the losses and profits of the Sony Corporation. This has been attributed to the PlayStation franchise's high profit returns for Sony; it has been the key source of profit for the company.

Ken Kutaragi is currently president and CEO of Cyber AI Entertainment Inc. He also serves on the boards of Kadokawa Group Holdings, Inc., Nojima Corporation, and Rakuten, Inc.

In 2009, he became a visiting professor of Ritsumeikan University.

Kazunori Yamauchi (山内 一典, Yamauchi Kazunori^?, born August 5, 1967) is a Japanese game designer, professional racing driver, and most notably, CEO of Polyphony Digital and producer of the Gran Turismo series. He became the president of Polyphony Digital after designing his first game Motor Toon Grand Prix, a cartoon-inspired racing title similar to Mario Kart. Motor Toon Grand Prix later spawned a sequel, Motor Toon Grand Prix 2, which was the only game in the franchise released outside of Japan. Since then, Yamauchi has fulfilled his dream of creating realistic driving simulators with his massively successful Gran Turismo series. He has also expressed interest in broadening out to other game genres; in 1999 Polyphony Digital released Omega Boost, a shoot 'em up title set in space, which has since proven to be Yamauchi's only foray outside of racing game development.

As a result of Gran Turismo's success, Yamauchi has become an important figure in the worldwide automotive industry. For his help with promoting Volkswagen models in the series, the company gave him a Golf R32.^{[citation needed]}. Polyphony Digital worked with Nissan to design the multifunction display (which relays various pieces of car data to the driver, including G-Force generated, torque distribution and lap times) found in the R35 GT-R. The car as well as the display itself appear in the latest game in his franchise, Gran Turismo 5.^{[citation needed]} He was given a Nissan GT-R for his contribution.^{[citation needed]}

Shigeru Miyamoto (宮本 茂, Miyamoto Shigeru^?) (born November 16, 1952) is a Japanese video game designer and producer. Miyamoto was born and raised in Kyoto Prefecture; the natural surroundings of Kyoto inspired much of Miyamoto's later work.

He is mainly known for his work at the video game production company Nintendo, where he created some of the most successful video game franchises of all time, including Mario, Donkey Kong, The Legend of Zelda, Star Fox, F-Zero, Pikmin, and the Wii series.

He currently manages the Nintendo Entertainment Analysis and Development branch, which handles many of Nintendo's top-selling titles. Miyamoto's games have been seen on every Nintendo video game console, with his earliest work appearing on arcade machines. His games have received critical praise from many reviewers, and he has been the recipient of various awards. He has a wife, Yasuko, and two children.

Miyamoto was born in the Japanese town of Sonobe, Kyoto on November 16, 1952. Miyamoto's later work was greatly influenced by his childhood experiences in the town. From an early age, he began to explore the forest around his home. On one of these expeditions, Miyamoto came upon a cave, and, after days of hesitation, went inside. Miyamoto's expeditions into the Kyoto countryside inspired his later work, particularly the Nintendo Entertainment System version of The Legend of Zelda. Miyamoto graduated from Kanazawa Municipal College of Industrial Arts with no job lined up. He also had a love for manga and initially intended to become a professional manga artist before considering a career in video games, where the manga influence in his work would later be evident. The title that inspired him to enter the video game industry was the 1978 arcade hit Space Invaders.
