It was revealed on the 6th that Koji Yamamoto (45), a member of the comedy duo Time Machine No. 3, broke a rib during the filming of the Fuji TV variety show "Celebrities Honestly Thought About It! Surprise GP" (Saturday, 7:00 p.m.). This was reported on the show's official website.

Fuji TV apologized on its website, saying, "During the filming of this program, Time Machine No. 3's Koji Yamamoto broke a rib. We would like to offer our sincere apologies to Yamamoto and all those involved. We pray for Yamamoto's speedy recovery, and will respond sincerely to any medical treatment for his injuries. We will be even more thorough in our safety measures for future program productions."

The injury occurred during the filming of the segment "Gerok Kuma-kun in a Second" on November 5th. This segment has aired before, and involves a prank where a teddy bear suddenly sprays liquid on the target. Yamamoto fell to avoid the liquid, damaging his rib. A doctor diagnosed him with a "fracture of the seventh left rib."
