RE Amemiya

RE Amemiya is a Japanese automotive tuning company founded in 1974 by Isami Amemiya and based in Tomisato, Chiba Prefecture. The company is particularly associated with Mazda vehicles powered by rotary engines, and the “RE” in its name refers to the rotary engine. Its activities span engine development, performance tuning, chassis and suspension work, aerodynamic body components, complete vehicle builds, and participation in motorsport and tuner competitions. The company’s reputation has been built around the Mazda RX-7 and other rotary-powered Mazdas. Rather than operating primarily as a mass-market parts brand, RE Amemiya is known for specialist engineering and highly visible demonstration cars. Its work commonly combines powertrain modifications with cooling, braking, suspension, drivetrain, exterior, and interior changes. The resulting vehicles are often designed both as road-going performance cars and as showcases for the company’s tuning philosophy. This approach has made RE Amemiya recognizable among Japanese sports-car enthusiasts, especially those interested in the RX-7’s technical and competitive potential. RE Amemiya has also used competition to develop and publicize its expertise. It entered Japan’s top-level GT racing environment in 1995 as a rotary-powered participant in the GT300 class, using a three-rotor 20B-powered RX-7. The team recorded a GT300 race victory in 2006, followed by additional wins and podium finishes. Its strongest championship result came in 2009, when it finished second in the GT300 standings. The team ended its Super GT participation after the 2010 season, finishing third in the GT300 championship that year. RE Amemiya also competed in the D1 Grand Prix drifting series from 2004, with driver Masao Suenaga winning at Fuji Speedway in 2005 and finishing second overall in that season’s championship. The brand’s public profile extends beyond formal racing. Its Mazda RX-7 builds appeared repeatedly in the Japanese automotive program Hot Version, where they took part in touge-style comparison battles against cars prepared by other specialist tuning companies. A blue FD3S RX-7 associated with RE Amemiya held the Hot Version “Maou,” or “Demon King,” title from 2004 through 2006. After losing the title in a rain-affected 2007 contest, the company reclaimed it in 2009 with a green FD3S. Across the documented contests, RE Amemiya won the title four times with three different cars. RE Amemiya-tuned RX-7s have also appeared in popular media and games. Body kits associated with the company were used on the FD3S and FC3S RX-7s of Keisuke and Ryosuke Takahashi in the Project D portion of Initial D. The company’s blue FD3S and its GT300 racing car have also been represented in the Gran Turismo racing-game series. These appearances reinforced RE Amemiya’s association with Japanese rotary performance, drifting, touge competition, and the broader tuning culture. The available reference material emphasizes the company’s historical achievements, competition vehicles, and cultural visibility rather than its current corporate structure, retail network, or financial performance. No reliable public information in the supplied sources establishes a current parent company, stock listing, revenue figure, or official website URL. RE Amemiya is therefore best characterized as an independent Japanese specialist tuning and motorsport brand centered on rotary-powered Mazda performance.

RE Amemiya was established in 1974 by Isami Amemiya in Tomisato, Chiba Prefecture. From its beginning, the company developed a specialization in rotary-engine vehicles, with the “RE” designation referring to the rotary engine. Its identity became closely linked to Mazda, whose rotary-powered sports cars—especially the RX-7—provided the principal platform for the company’s tuning work. The company’s activities developed beyond ordinary repair or aftermarket parts supply. RE Amemiya became known for integrated performance builds that could include rotary-engine tuning, turbocharging and exhaust work, cooling improvements, suspension and brake upgrades, drivetrain preparation, chassis refinement, and aerodynamic bodywork. Its complete cars served as both customer-oriented performance products and highly visible demonstrations of the company’s engineering approach. The FD3S and FC3S generations of the RX-7 became particularly important to the brand’s identity. RE Amemiya entered the GT300 class in 1995 with a three-rotor 20B-powered RX-7. As a specialist rotary entrant, it occupied a distinctive position in a field that also included other Japanese performance manufacturers and tuners. The program achieved a GT300 victory in 2006 and subsequently added three more race wins and eleven podium finishes according to the documented record. In 2009, RE Amemiya finished second in the GT300 championship, narrowly behind Racing Project Bandoh’s Lexus IS350. In 2010, its final recorded Super GT season, the team finished third in the GT300 championship behind Hasemi Motorsport and Autobacs Racing Team Aguri. The company entered the D1 Grand Prix drifting series in 2004. During the 2005 season, RE Amemiya driver Masao Suenaga won at Fuji Speedway and finished second in the overall championship, losing the title by a single point to Yasuyuki Kazama. This program further connected the company with Japan’s performance-driving and tuning communities. A major part of RE Amemiya’s cultural visibility came from the television program Hot Version. Its cars participated in touge-style, head-to-head battles against vehicles prepared by rival tuning specialists. The company’s blue FD3S RX-7 held the program’s “Maou,” or “Demon King,” title from 2004 through 2006. It lost the title to a J’s Racing Honda S2000 in a rain-affected 2007 contest, then regained it in 2009 with a green FD3S. The documented record credits RE Amemiya with four Maou victories using three different cars. RE Amemiya’s vehicles also circulated through anime, manga, and video games. In Initial D, body kits associated with the company were fitted to the FD3S and FC3S RX-7s used by Keisuke and Ryosuke Takahashi during the Project D storyline. The company’s blue FD3S and GT300 race car were also included in the Gran Turismo series. These appearances helped make RE Amemiya recognizable outside Japan and strengthened its association with rotary tuning, touge racing, and Japanese car culture. The supplied references do not document a later ownership change, corporate restructuring, financial results, or a confirmed official website address. The available history therefore supports describing RE Amemiya primarily through its founding, rotary-engine specialization, competition programs, tuner-event record, and popular-culture presence.
