Built on a small budget and in a short time, the Karasu emphasized weight reduction and aerodynamics using FRP materials.

[2] In 1975 at Takaragaike, Kyoto, Hayashi formed Dome with the intention to manufacture cars with small production runs, using racing machines to develop the technology.

A 320 was also modified for the Formula Atlantic category and won the Macau Grand Prix driven by American Bob Earl.

In 1984, the follow-up Hayashi 322 was a success and helped Shuji Hyodo to win that year's Japanese F3 championship.

In 1985, the Hayashi 330 won a single Japanese F3 race, but finishes were good enough to place driver Shuji Hyodo third in season-end standing.

The Formula 3000 program continued until 1998 with Shinji Nakano, Katsumi Yamamoto and Juichi Wakisaka but without much success.

The planned 1997 World Championship effort came to nothing and the follow-up car, the Dome F106, never materialised due to lack of sponsorship and Mugen's refusal to supply engines.

It continued to build and race the Honda NSX in the recently-renamed Super GT series, with Takata as the main sponsor.

[citation needed] In 2014, Dome left Super GT as a team entrant to focus on the construction of the Mother Chassis platform for the GT300 class; the team was reported to return in 2017, but did not materialize in favor of entering a Honda Civic TCR in the Super Taikyu Series.
