Koji wasn’t on the forums much, he was mostly a lurker. He was also friends with Naoki. But Koji had a profound impact on f31club. His M30 coverage helped elevate F31club to new heights.
Koji’s M30 was the project car M30.
I believe he was going to do more with the M30, but found out he was having twins… and so family priorities come first!
