Monte Carlo, Monaco – March 22, 2026 – Princess Akiko of Mikasa made a notable appearance at the 70th annual Rose Ball in Monaco on March 21st, at the personal request of Princess Charlène. The event, a highlight of the Monegasque social calendar, celebrated its anniversary under the theme “Galaxy Rose Ball” and benefited the Princess Grace Foundation.

A Royal Visit Rooted in Diplomacy and Sport

Princess Akiko’s visit to Monaco is part of a broader European trip from March 16th to 24th, 2026. Her presence at the Rose Ball coincides with the 20th anniversary of diplomatic relations between Japan and Monaco, elevating the event’s significance beyond its traditional glamour. The visit was facilitated by Cédric Biscay, an entrepreneur and manga author who served as a special advisor for Expo Osaka, bridging connections between the two nations.

From Rugby Tournament to Royal Gala

Prior to the Rose Ball, Princess Akiko attended the Sainte Dévote U12 Rugby Tournament, where a Japanese team participated for the first time. Princess Charlène specifically invited the Japanese team to Monaco, and Princess Akiko, a patron of the Japan Rugby Football Union, was present as Honorary Patron. The royal couple extended an invitation to Princess Akiko to attend the Rose Ball, capitalizing on the timing of the rugby tournament.

A Historic Evening for the Mikasa Family

Princess Akiko’s attendance at the Rose Ball is particularly noteworthy as she recently became head of the Mikasa family in September 2025, following the passing of her grandmother, Princess Yuriko, in November 2024. This marked the first time since the Meiji era (1868-1912) that a princess who is a great-granddaughter of an emperor has led a branch of the imperial family.

The Rose Ball: A Legacy of Glamour and Philanthropy

Established in 1954 by Princess Grace of Monaco, the Rose Ball has become synonymous with elegance and charitable giving. This year’s event, designed in collaboration with Christian Louboutin, raised funds for the Princess Grace Foundation, continuing its tradition of supporting artistic endeavors. The ball was attended by a host of dignitaries, including Prince Albert II, Princess Charlene, Princess Caroline of Hanover, Pierre Casiraghi, Beatrice Borromeo, and Princess Alexandra of Hanover.
