Hakosuke (Japanese: はこすけ Hakosuke) is a recruitable Toyota bB found in Fuji City. Hakosuke wants you to hear his trumpet. You can refuse to hear it, however if you choose to listen to it, he'll give you a Trumpet Horn and you will receive Stamp 19. To get to his house, you must drive on the side of a cliff because there is a gate in the main Fuji City town blocking his house. When doing this you must be careful so that you don't fall into the Grand Ocean. Hakosuke says he has to live far away because he plays the trumpet.
- "I'm Hakosuke! I live away from the city because I play the trumpet! Will you listen?"
- (Plays the trumpet) "Pa pa pa... pa pa pah. I'm saying this because you have the potential. How is it? Sounds good, huh? Take this! See you! Well, come and listen to me if you're in the mood!"
- "Hey! You should practise racing. I'm saying this because you have the potential."
- (Before recruiting him) "Actually, I'm good at racing. Are you satisfied with your teammates? Don't you want me on your team?"
- (Declining his request) "Oh, too bad. Well, come see me if you change your mind!"
- (Accepting his request) "Yes! I'm excited! You won't regret this!"
- (Whilst on the team) "Hey! Doing well? You make me feel excited about the next race!"
- "Well, I'll practise racing. Keep up the good work."
