Description: Why did Takashi Okamura chase Hiroyuki Yabe into a booth and cover him in black powder at the October 24, 2026, All Night Nippon festival? The radio joke, drama-set origin and punchline explained.
Short answer: “Kona Ningen,” literally “Powder Human,” was a nickname listeners gave Japanese comedian Takashi Okamura after he discussed having dark cosmetic powder applied to his hair during a drama shoot. At the October 24, 2026, Ninety-Nine All Night Nippon music festival, he turned that throwaway radio joke into a mock horror villain and dumped black powder over his comedy partner Hiroyuki Yabe.
From a love song to a horror entrance
The event took place at Yokohama Arena, with a scheduled 4:30 p.m. start and a reported audience of 12,000. It was a concert-style event attached to a long-running Japanese late-night radio show, with a paid stream—not a regular television episode.
Yabe appeared in a white tuxedo and began singing Southern All Stars’ ballad “Itoshi no Ellie.” The music cut out. A video of Okamura appeared, accusing people of mocking him and announcing his revenge. He then pursued Yabe onstage as the ominous “Kona Ningen.” Yabe hid in a phone booth; black powder poured down on him. When Yabe insisted he had never made fun of Okamura, the supposedly terrifying monster quickly apologized. One on-site account adds that the powder kept falling because the character did not know how to stop the mechanism. Yabe resumed the song while still covered.
Where did the name come from?
Both members of the comedy duo Ninety-Nine appeared in the 2026 TV Asahi drama Meitantei no Mama de Ite. Reports connect the nickname to Okamura recounting the dark hair powder applied during that production. Listeners started calling him “Kona Ningen,” and the phrase became a recurring radio bit.
A separate eyewitness report also mentions the radio show's conversation about Netflix's Gas Ningen (“Gas Human”) as part of the wordplay surrounding the name. That is context for the joke, not evidence of an official crossover or a fictional franchise character.
Why was it funny?
Japanese variety comedy often builds a sketch by treating a tiny embarrassment as if it were a world-ending crisis. Here, a routine makeup detail became the origin story of a monster. A romantic ballad became a chase sequence. And the threatening creature turned out to be surprisingly polite once Yabe explained himself—while the physical gag carried on regardless.
Longtime listeners had another surprise: previous festivals had opened with Takashi Sorimachi’s “POISON,” making the altered musical entrance part of the setup. Newcomers only need two translations: kona means powder, and tsukkomi is the partner who calls out the absurdity. Yabe supplied that grounded reaction.
Date, replay and conclusion
The organizer confirms Saturday, October 24, at Yokohama Arena; some October 25 articles mistakenly describe the event as taking place that day. The official replay window runs through November 1 at 11:59 p.m. Japan time. This account is based on the organizer and on-site reporting, not a claimed viewing of the entire paid stream.
Yabe was also due to leave the duo’s shared radio show on October 29, giving the concert an emotional undertone. Yet its opening image was pure absurdity: a decades-old comedy partnership, one phone booth, and a radio nickname upgraded into an arena-sized powder storm.
