Japan's Prince Hisahito turned 20 on September 6, 2026. This was reported by Qazaqyia.kz citing Associated Press.

Prince Hisahito is the eldest son of Prince Akishino, the younger brother of Emperor Naruhito. He is second in line to the throne. His coming of age is an official recognition of adulthood in Japan. This event has reignited debates about imperial succession in the country.

The Japanese government, ahead of the prince's birthday, reaffirmed the rules that allow only male heirs to ascend the throne. According to these rules, only male heirs of the emperor can become emperor. Prince Hisahito is the only male in the current imperial family who is in the line of succession. His father, Prince Akishino, is first in line, and Hisahito is second.

On August 13, 2026, Hisahito visited the Science Museum of Map and Survey in Tsukuba, Ibaraki Prefecture. This visit was part of events organized for his birthday. The Imperial Household Agency released photos from this visit.

Prince Hisahito's 20th birthday is a significant event for the future of Japan's imperial family. In recent years, there have been debates about changing the succession rules. Some experts and politicians argue that women should also be allowed to inherit the throne. However, the government maintains a conservative stance and prefers to keep traditional rules.

Hisahito is the first boy born into Japan's imperial family in 40 years. Before his birth, only girls were born. This caused disputes over succession. Hisahito's birth temporarily resolved the issue.

To mark the prince's 20th birthday, various ceremonial events are held in Japan, including official receptions and traditional rituals at the palace. Hisahito can now fully participate in official events as an adult member of the imperial family.

As reported by Associated Press, Hisahito's birthday is a crucial moment for the future of the monarchy in Japan. Experts view this event as the beginning of new discussions on imperial succession.
