Mr. Katori, president and owner of Katori Motors, personally recruits Takaya Todoroki after spotting his potential beyond early setbacks in the Alpine Road Rally. He believes in Takaya's talent and innovative vehicle design approach. His own background as a competitive youth motorcycle racer informs this decision, recalling his professional track rivalry with Takaya's father, Takagi Todoroki, alongside their off-track friendship.

Leading Katori Motors, he bankrolls Takaya's racing career and the development of distinctive "Todoroki Special" prototypes. He demonstrates unwavering confidence in Takaya, supporting him through technical hurdles and competitive losses in early Formula 1 seasons. His backing facilitates Takaya's participation in major events like the Monte Carlo Rally, the 24 Hours of Le Mans, and the African Rally-Safari.

Personally, he is father to Rie Katori and accepts her relationship with team driver Masaru Oohinata, Takaya's initial rival. Following Masaru's fatal Formula 1 accident, Mr. Katori persists with team development. He later steers Katori Motors into the new Formula 0 category amid involvement from major automotive powers like the US and USSR. During Takaya's temporary withdrawal, he actively seeks a replacement, recruiting Hans Rosel while simultaneously pursuing Takaya's return.

His management trusts key individuals, granting Takaya significant autonomy in design and strategy. He navigates corporate challenges including international boycotts and technical rivalries, focusing on advancing both Takaya's career and Katori Motors' global standing.
