As an owner, Hattori owns Hattori Racing Enterprises, which currently competes full-time in the NASCAR Gander RV & Outdoors Truck Series and the ARCA Menards Series East. HRE also has competed part-time in the Xfinity Series and the ARCA Menards Series in the past. The team has fielded cars for Johnny Sauter, Alex Bowman, Austin Hill, Max McLaughlin, David Garbo Jr., Lee Pulliam, Brett Moffitt, Sergio Pena, Ross Kenseth, Jesse Little, and Ryan Truex. His race team won the 2018 NASCAR Camping World Truck Series championship with Brett Moffitt.

In 2016, Kenseth was replaced by Ryan Truex in Hattori’s truck ride (renumbered from the No. 18 to the No. 81 due to Kyle Busch Motorsports re-taking that number). After the team gave Truex that chance, he nearly won the season-opening race at Daytona, where he finished second. After that strong run, the team and Truex said they would try to run the full season, which ended up not happening due to sponsorship issues. However, Truex drove part-time for the team in select races for the remainder of the season.

Beginning in 2008, Hattori has fielded entries in NASCAR and ARCA competition under the Hattori Racing Enterprises banner. On August 18, 2013, he made his debut as a NASCAR Camping World Truck Series team owner, fielding the No. 16 Goodyear of Japan Toyota at Michigan International Speedway in the National Guard 200. The team finished 17th. Hattori’s team returned in 2014, fielding the 80 in several Nationwide series events. In 2015, the team fielded the No. 18 for Ross Chastain at Michigan, but he failed to qualify after the rain interrupted. Later on, the team will host Ross Kenseth’s first Truck start in the No. 18 at the Fall Martinsville event.

Hattori moved to the United States in 1995, and began competing in the Indy Lights series in 1996 at the age of 32. After finishing 13th and 25th in points in his first two seasons, he scored his first career win in the series in 1996 at the season-opener at Homestead Miami Speedway. He would win two races that season and finish 14th in points.
