A well-known local figure in Japan, often spotted walking around Exit 8, has been consistently emphasizing the importance of wearing a hat while going outside. Known as the "Hat Man," he seems to have struck a chord with the Japanese public who admires his effort to promote sun safety awareness.
In Japanese society, people take their public behavior quite seriously. Modesty and politeness are highly valued. In addition, sun protection is often considered a major aspect of personal care in Japan, which could explain the popularity of the 'Hat Man's' message.
In the US or EU, sun safety is also emphasized, but the modes of advocating for it may vary. Celebrities and influencers on social media often spearhead campaigns promoting wearing hats or sunscreen, and there tends to be more use of advertising for these issues.
