Popular Japanese actor Hiroto Kiriyama has been diagnosed with both prostate and colorectal cancer. The news has been released to the public, while the actor reassures fans that the cancers were caught early and are being treated. The age and details about the treatment process have not been shared, maintaining respect for Kiriyama’s personal privacy.

In Japan, health issues of celebrities are usually treated with a high level of respect for privacy. However, the news is shared when relevant to raise awareness about certain health issues and encourage regular health checks. The social value here revolves around the support received from fans and the opportunity to promote public health awareness.

Much like in Japan, the USA and EU also respect the privacy of their celebrities' health issues. However, when made public, there is a similar showing of fans' support, and often celebrities choose to use their platform to raise awareness and funds for research and treatment of their specific health issues.
