A man who owns a repairing shop (a reference to Ruf Automobile). He is also tuning people's cars (including his Skyline). His C10 Skyline (known as Hakosuka, or Boxy Skyline) has a tuned L28 engine and some useful performance enhancements such as an intercooler. However, during a battle with Mayumi the 7th, his Skyline quickly got wiped out, and crashed into barriers, but he managed to repair it. He had dreamt of driving his Skyline in Fuji Speedway, and was interested in cars and women. He also owns a dog.

Junichi Nomura is incidentally named after Ken Nomura, a D1 Grand Prix driver and former baseball player who currently uses Nissan Skylines.
