Hasegawa Ken (長谷川 健) entered three SASUKE tournaments. As he worked at a theme park portraying a ninja, he always competed in a ninja costume. Like Kobayashi Masaaki, he was known for his consistency in his short stint on SASUKE. He reached the Final Stage in the SASUKE 1, but failed the new Pipe Slider -- which had replaced the Hariyama as Stage Three's last obstacle -- the next two times and retired from competition.
Today, he still works at the same theme park, Edo Wonderland (日光江戸村), in Nikko, Japan; he's worked there for nearly 20 years.
