Naoki Hattori is a Japanese former racing driver who participated in different racing disciplines, including an attempt in Formula One. He entered two F1 Grand Prix events with Coloni in 1991, failing to qualify for both races. In 1997, he was a test driver for Dome F1 team which never entered an F1 Championship.
In other open-wheel competitions, Hattori was Japanese F3 champion in 1990 and spent thirteen seasons in the Japanese Formula 3000/Formula Nippon, finishing best as a vice-champion in 1996 and 2001. He also spent two seasons in the Indy Lights Series and raced on a part-time schedule with Walker Racing in the 1999 CART Championship.
Outside open-wheel racing, Hattori gained some success in touring car and sports car racing. In 1991, he won 24 Hours of Spa in a Nissan Skyline R32 GT-R, together with David Brabham and Anders Olofsson. Five years later, in 1996, he was Japanese touring car champion with Honda Accord. In the Japanese GT Championship, Hattori's best result was the second place in 1996 with McLaren F1 GTR.

In October, Hattori made an F1 debut in the Japanese Grand Prix at Suzuka Circuit, failing to qualify for the race. He was the slowest in pre-qualifying. Two weeks later, Hattori had one more unsuccessful F1 attempt in the Australian Grand Prix at Adelaide Street Circuit. He was again the slowest driver in the pre-qualifying.
Collecting victories in Japanese championships

He scored one victory in each championship, finishing fifth in F3000 and third in JTCC. In 1993, he was without wins in Formula 3000 and Class 3 champion in the JTCC with four wins.
In 1994, Hattori expanded his programme to Japanese GT Championship, driving a Nissan Silvia for Mooncraft. In the JTCC, he continued to drive Honda Civic for Mooncraft while in Formula 3000, he joined Team LeMans.
Le Mans 24h debut in 1995 with Honda NSX GT1
In 1995, Hattori was active again in the JTCC and F3000 but also recorded two starts in the International Formula 3000. The highlight of the season was his debut in world's greatest race - the 24 Hours of Le Mans.
Japanese touring car champion in 1996
In 1996, Hattori added one more championship title to his account, winning the Japanese Touring Car Championship with Mooncraft's Honda Accord. He was a race winner five times in twelve races.

Hattori also won two races in the Formula Nippon, what was a new name for Formula 3000, finishing second in the championship behind his Team LeMans colleague Ralf Schumacher.
Test driver for Dome F1 team
