Yamamoto Hiroshige is an SEGA Attendant and also a member of SASUKE All-Star Yamada Katsumi's group, the Black Tigers.
He debuted in SASUKE 29 and wore #47, failing the Jump Hang Kai.
In the next tournament SASUKE 30, he cleared the Jump Hang Kai and became the second person that day to clear the First Stage with 18.4 seconds left. In the Second Stage, Yamamoto was disqualified on the Swap Salmon Ladder when the bar landed improperly on the last set of rungs.
In SASUKE 31, he once again cleared the First Stage, but in the Second Stage he was slowed down by the Backstream. It took him three attempts to get past the rapids and he timed out just as he got out of the pool.
In SASUKE 32, he moved though the first 6 obstacles in a decent pace. He took several attempts at the Soritatsu Kabe, but still had made it up. This however slowed him down enough to time out by 0.1 second on the Lumberjack Climb.
Yamamoto next competed in SASUKE 33, but failed in the First Stage for the second time in a row, as he was eliminated at the Fish Bone.
