We must know that Japan, being the strongest racing country in Asia, not only has manufacturer teams from car companies but also many sponsored teams with modified parts, such as Dome and Mugen.
Then there are private teams established by drivers after retirement, like Kunimitsu and Aguri.
Compared to sponsored teams and private teams, manufacturer teams naturally have more resources and talent-attracting capabilities.
However, in lower-tier formula racing, since standardized race cars are used, the advantage in technical leadership is not obvious; it is more about the driver's personal ability, and having good talent offers a chance to win the championship.
In fact, Japanese domestic car races, such as Super GT, have never been the sole domain of factory teams; instead, it's been a thrilling competition among many strong teams for decades.
