If you had the opportunity to meet Masumoto just once, then it would go without saying that he is the definition of someone who lives for circuit racing. The energy that he resonates around the track is that of true happiness and excitement to be doing what he does. Over the past few years he has helped the Attack series grow into something much more than just a private, invite only track event. The fact that Attack is now a recognized championship series throughout Japan is thanks in part to Masumoto-san’s hard work and dedication. His personal GTR build has paralleled his work with Attack, and provides him the outlet he needs to channel his energy.
