Yokoyama, a member of the popular Japanese idol group Morning Musume, has publicly disclosed her battle with Ménière's disease, a condition that affects hearing and balance. Yokoyama acknowledged her situation during a live broadcast, sharing her struggles with the public in an effort to raise awareness about the condition. As she continues her medical treatment, Yokoyama has expressed gratitude for the fans' overwhelming support and understanding.

In Japan, issues regarding celebrities' health are treated very seriously. The revelation of such health concerns by famous personalities often includes assurances that the individual will continue to work as much their condition allows, with a strong emphasis on fan support. As health is a sensitive and highly personal issue, public disclosure is seen as a measure of trust and often leads to better understanding and social awareness of specific conditions like Ménière's disease.

Similar to Japan, celebrities in the US or EU would likely receive an outpouring of support from fans upon revealing serious health issues. However, because of different cultural perceptions of health and privacy, Western celebrities may be more likely to keep such issues private until necessary for public disclosure.
