Tosa's Pole and Line Fishing PART 2 Junpei

Junpei Komatsu became a bonito fisherman right after junior high. He married his childhood sweetheart Yachiyo, and they had a son, Akira. With Junpei away fishing for most of the year, Akira grows up to be a stubborn and mischievous child, so much like his father that they call him "Ko-Jun."
