Crown Princess Masako celebrated her 51st birthday Tuesday and released a statement through the Imperial Household Agency expressing her gratitude for an opportunity to meet the king and queen of the Netherlands last month.
"I'm happy and grateful for having had the opportunity to greet [the royal couple]," she said in the statement in reference to a banquet that she attended at the Imperial Palace.
It was the first time in 11 years for Crown Princess Masako, who is receiving treatment for an adjustment disorder, to attend such a banquet.
In the statement, the crown princess also looked back at a visit to Ise Grand Shrines in Mie Prefecture in July and observing the National High School Games with her 13-year-old daughter, Princess Aiko, who entered Gakushuin Girls' Junior High School this spring. "I hope my daughter will experience various things in and outside of school life," she said.
Regarding her health condition, the crown princess said: "I have been making the greatest possible efforts both in official and personal lives. I want to keep working toward my recovery."
A team of doctors for the crown princess explained, "Although her condition is steadily improving, she is still in the process of recovery and has good and bad days."
The official duties conducted by the crown princess for the year decreased to 30 from 33 the previous year, according to the Imperial Household Agency.
