The official TEAMZ speaker pages, '堀江 貴文 | TEAMZ SUMMIT 2026スピーカー' and '國光宏尚 | TEAMZ SUMMIT 2026スピーカー', support the narrower proposition that Takafumi Horie (Horiemon) and Hironao Kunimitsu were featured by TEAMZ as speakers. However, the stronger parts of the claim — that they discussed Bitcoin and Web3 together at a Tokyo event and that the post highlights efforts to revitalize Japan’s Web3 sector — were not directly confirmed by a validated agenda page, session description, transcript, or successfully fetched primary post. Because the two cited X URLs could not be fetched and search corroboration was sparse, the available evidence is suggestive but not sufficient to fully verify the full statement.
