Japanese research service for No.1 and first-of-kind advertising claims
TEIKOKU NUMBER ONE RESEARCH (帝国ナンバーワンリサーチ組合), operated by 帝国ナンバーワンリサーチ合同会社, is a Japan-based research service for No.1 and first-of-kind advertising claims. It combines preliminary AI screening with human-reviewed research and evidence reports. Its free Japanese-language first-check tool uses generative AI and web search to identify possible prior examples. AI screening results do not prove that no prior examples exist and cannot substantiate an advertising claim; human research services are separate.
