Princess Aiko's increasing popularity is sparking discussions about changing Japan's male-only succession law. Aiko is the only child of the current emperor and cannot succeed him under the law. Experts say lifting the female ban is crucial to the monarchy's future, but conservative lawmakers oppose it. The monarchy has only one eligible heir from the younger generation. Aiko turns 24 on Monday, and many fans want her to become a future monarch. Her charm and intelligence have won admirers, and her recent solo trip to Laos further boosted support. The monarchy's future remains uncertain, with debates ongoing about gender equality and succession rules.
