As Okuyama explains, each car he designs is commissioned by a customer, and it's not a speedy process. He says the design phase takes about two years, and so he half-jokingly says that he and the customer need to get along. It's definitely a joint process with back-and-forth. Okuyama highlights the nose of the car where the owner initially wanted something more, but Okuyama pushed for the extra simple design, specifically because he felt the simple fascia was more reminiscent of the '70s and '80s supercars that inspired the car.
The episode also gives us a peek at the next project from Okuyama. He shows Leno his sketchbook as an example of the drawings he does for customers. The sketches are of a project that Okuyama says might be revealed next year. It looks like a front-engine sporty grand tourer of some sort.
