Comparative advertising

Japan / MHLW

Product-to-product comparative advertising is limited to the advertiser's own products with the comparator product named, and comparative advertising against other companies' products is prohibited whether explicit or implicit.

製品同士の比較広告は自社製品の範囲内で対照製品の名称を明示する場合に限られ、他社製品との比較広告は明示的か暗示的かを問わず行ってはならない。

Note
解説の第4の9(2)。基準本文(薬生発0929第4号)第4の9は「他社の製品の誹謗広告の制限」を定めるのみで、比較広告の可否は本解説通知に置かれている点に注意。解説は同(2)①で、漠然と比較する場合も第4の3(5)(保証表現の禁止)に抵触するおそれがあるとする。
Every cell carries a summary, a source and a date checked. Topics whose source has not been verified are left marked “not researched” rather than filled with plausible text. Directives and statutes bind as to the result; what applies in practice is national implementing law. This is a research aid, not legal advice.
