Japanese television personality Hiroyuki Ariyoshi startled fans when he announced the birth of his second child at 51. Known for his work in comedy and as a television host, Ariyoshi's private life rarely makes the headlines. The news has sparked surprise among fans and the wider public, as Ariyoshi becomes part of a growing trend of older parenthood in Japan.

In Japan, celebrity news, especially about their personal lives, is often carefully controlled, so Ariyoshi's announcement was all the more striking. There's also a growing trend of becoming parents in later lives. This awareness is seen as a reflection of the country’s broader demographics, with the national age of first-time parents gradually rising.

In the US or EU, celebrity news about relationships and children is more commonplace, and a celebrity becoming a parent at an older age would cause less of a stir. It's also more accepted and common to see celebrities having children at an older age due to professional commitments or personal choices.
