Hasegawa Ken

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. In the first tournament, he cleared the First Stage with an impressive 20 seconds left. In the Second Stage however, he struggled, but still cleared the stage with only one tenth of a second remaining. His record was tied by James Okada in SASUKE 7 but their records were crushed by Ishikawa Terukazu, when he left just six hundreths (0.06) of a second remaining in SASUKE 27. He reached the Final Stage in SASUKE 1, but failed the new Pipe Slider, which had replaced the Hariyama as the Third Stage's last obstacle, the next two times and retired from competition.

He and Yamamoto Yoshiyuki are the only two competitors to compete at least 3 times without failing either the First or Second Stage.

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.
