Tsuyoshi Kusanagi, popular member of SMAP, a renowned Japanese boy band, was reportedly spotted on location with a serving of Miso soup, leading to speculations about his unique health regimen. It is suggested that Kusanagi's daily consumption of this traditional Japanese dish has a significant contribution to his enduring fitness and youthful appearance. Further details about the artist's approach towards healthy living are yet to be revealed.

In Japan, celebrities' health and diets often attract public interest, as people look up to them for lifestyle inspiration. This particular news is likely to spur a renewed interest in traditional Japanese cuisine, Misoshiru in particular, given its health benefits.

In the US or EU, celebrity dietary habits also gather considerable attention. Companies frequently tie up with such public figures to market their health and fitness products. However, traditional or local cuisine isn't usually highlighted in such reports, unlike in Japan.
