Following Princess Kako of Japan, also known as Kako-sama, appearing in public with a certain pair of earrings, a surge in orders for the same piece is being reported by Japanese retailers. The royal influence in sparking fashion trends is undeniable as the Japanese public shows immense interest in the princess's sartorial choices. Exact details about the jewelry or the event that prompted this surge are not elaborated in the headline.

In Japan, the Imperial family holds a significant influence over culture despite having no political power. Members of the royal family are often seen as trendsetters. With this event, the public demonstrates their respect and fascination for the royal family, ultimately shaping fashion trends. The issue also highlights the influence of pop culture in Japan, and the strong emotion of respect towards the royal family.

This incident is indicative of a global phenomenon where public figures including royalty impact fashion trends, much like in the UK where anything worn by the Duchess of Cambridge or Sussex often leads to the 'Kate or Meghan effect'. In the US too, fashion choices of celebrities or notable figures often create buzz and influence consumer behavior.
