Neutral keywords, such as ``vaccine'' and ``prevention,'' appeared more frequently in newspaper articles, whereas negative keywords, such as ``infertility'' and ``side effect,'' appeared more frequently in Web pages. The extraction of the positive keyword ``signature campaign'' suggests that vaccine beneficiaries cooperated with providers in promoting HPV vaccination. Conclusions: The rapid development of a national agreement regarding HPV vaccination in Japan may be primarily attributed to the advocacy of vaccine beneficiaries, supported by advocacy by celebrities and positive reporting by print and online media.
