About

Hitmaker Co., Ltd. was a semi-independent Sega development studio, formerly known as Sega AM3, that operated from 2000 to 2004. The studio is best known for Crazy Taxi (1999/2000), an arcade and Dreamcast game directed by Kenji Kanno, and Virtua Tennis (1999/2000), produced by Mie Kumagai — who in 2003 became the world's first female head of a video game studio (Guinness World Records certified). The studio was dissolved back into Sega on July 1, 2004, ahead of the Sega Sammy merger.

History

In April 1993, Sega opened its AM3 studio under the leadership of Hisao Oguchi as part of the company's internal Amusement Machine development organization. Where AM2, led by Yu Suzuki, pursued technical perfection in polygon-based combat simulation — Virtua Fighter, Daytona USA — AM3 took a different angle: racing, sports, simulators, and titles that placed the player inside a specific role or vehicle. The studio's wider remit gave it room to experiment in ways AM2's signature precision did not, and over the following years it would develop into one of Sega's most creatively diverse development groups.

AM3's early years produced a varied range of arcade titles. Star Wars Arcade (1993) and Jurassic Park (1994) adapted major licensed properties to Sega's powerful Model 1 and System 32 hardware. Sega Rally Championship (1995) — produced by Tetsuya Mizuguchi before he departed to form AM Annex — became a breakout Japanese arcade hit. Virtual On: Cyber Troopers (1996), designed by Juro Watari with an unprecedented twin-stick controller, found a dedicated competitive community. Top Skater (1997), directed by Kenji Kanno, hinted at the aesthetic that would fully emerge in Crazy Taxi: fast, sensory, prioritizing the feel of motion over the simulation of sport.

Juro Watari's Virtual On: Cyber Troopers, released in 1996, was a mecha combat game built on hardware that did not yet exist when development began. Watari had to argue internally at Sega for the twin-stick cabinet to be manufactured at all — the controller had no precedent in arcades. The game created its own community: a small but devoted competitive scene that felt like the discovery of a genre rather than the release of a product. Virtual On: Oratorio Tangram followed in 1998, adding depth and new units. The series survived AM3's corporate transformations and eventually reached home consoles across multiple generations.

Kenji Kanno had joined Sega in 1993 and spent his first years in relative obscurity. Jurassic Park (1994, assistant director) and Funky Head Boxers (1995, director) both performed below expectations. Top Skater (1997) was his first success. By the time Kanno began developing what would become Crazy Taxi, he had a central thesis: the dominant driving games of the era required players to stay on the road. What if the road was optional? The idea arrived — as Kanno has described — from the fantasy of cutting across a traffic jam rather than sitting in one. When a colleague suggested the driver could be a taxi driver, the concept snapped into place: a fare to collect, a passenger to deliver, time running down, and every shortcut available.

Crazy Taxi launched in Japanese arcades in February 1999 on Sega's NAOMI hardware. Its design broke conventions deliberately: time extended through successful fares rather than depleting uniformly; the city was open rather than channeled; the soundtrack — provided by punk bands Bad Religion and The Offspring — treated the game as a concert rather than a simulation. The Dreamcast port arrived in 2000 and sold approximately 1.1 million copies in North America, ranking among the platform's top-selling games lifetime. Electronic Gaming Monthly named it Game of the Month; it received the Interactive Achievement Award for Console Action Game of the Year. The game's cultural reach extended beyond sales: Crazy Taxi's aesthetic represented a philosophy that a game did not need to simulate competence to generate joy.

Mie Kumagai joined AM3 as a producer and developed Virtua Tennis — released in Japanese arcades in 1999, on Dreamcast in North America in July 2000 — as a game built around accessibility rather than simulation precision. Earlier proposals for the project had included basketball; tennis won out for the universality of its premise and the visual clarity of its court. The Dreamcast version earned a Metacritic score of 92, with reviewers citing it as the best sports game and one of the best multiplayer experiences of the year. It generated a franchise of annual releases spanning over a decade. In 2003, when Hisao Oguchi was elevated to Sega's corporate presidency, Kumagai succeeded him as studio head — becoming, at thirty-five, the world's first female head of a video game studio, a distinction officially certified by Guinness World Records in July 2003.

On April 21, 2000, Sega reorganized its R&D operations into ten semi-independent subsidiaries, each with its own president, financial responsibility, and identity. Oguchi named his company Hitmaker Co., Ltd. The name was a declaration of intent. Peer companies formed simultaneously included Sonic Team, WOW Entertainment, Overworks, Amusement Vision, and United Game Artists — collectively the most concentrated assembly of arcade and console development talent in Japan at the time. Hitmaker began its independent life with approximately 128 employees and a portfolio including the Virtual On series, the Crazy Taxi franchise, and the growing Virtua Tennis property. The subsidiary model was designed to sharpen creative identity. For four years, it worked.

On July 1, 2004, Sega recalled its scattered subsidiaries — Hitmaker, WOW Entertainment, Smilebit, Amusement Vision, Sonic Team, and others — back into the parent company's corporate structure. The decision preceded by three months the October 2004 formation of Sega Sammy Holdings, the conglomerate created through Sega's merger with pachinko manufacturer Sammy. The subsidiary model had produced remarkable games but fragmented corporate strategy; Sega's persistent losses through the early 2000s, compounded by the Dreamcast's market exit, left the company without the stability to sustain the experiment. Hitmaker closed its website on July 1, 2004. Kenji Kanno eventually returned to the Crazy Taxi franchise decades later as director of a new instalment. The studio's name had been a declaration. The declaration turned out to be enough.
