Prince Hisahito, the only male grandchild of Emperor Emeritus Akihito and Empress Emerita Michiko,turned 18 years old on September 6, 2024. This significant milestone marks the first time in four decades that a male member of the Japanese royal family has reached adulthood.
Prince Hisahito’s birth in 2006 was met with much anticipation as it provided a much-needed male heir to the Chrysanthemum Throne. His father, Prince Akishino, is the second son of Emperor Emeritus Akihito and Empress Emerita Michiko.
As a newly adult member of the royal family, Prince Hisahito will assume greater responsibilities and public duties. He is expected to play a crucial role in preserving the traditions and continuity of the Japanese monarchy. While his exact future roles have not been formally announced, his education and upbringing have prepared him for a life of service to his country. 
The Japanese royal family has been undergoing significant changes in recent years. The abdication of Emperor Akihito in 2019 and the ascension of his eldest son, Naruhito, to the throne have brought about a new era for the monarchy. Prince Hisahito’s coming of age further underscores this transition and offers hope for the future of the Imperial House.
