While we have been enjoying the frilly and fun hats of Ascot, the Japanese royal family have quietly gone through the rituals of saying goodbye to a family member. On June 8, 2014, Emperor Akihito’s first cousin, Prince Yoshihito of Katsura passed away at the age of 66 years old. In the following days, members of the Imperial family called to pay condolence visits. Some of these family members wore hats.

On June 15, the Imperial couple paid another condolence visit to the Akasaka Estate Residence. Again, Empress Michiko wore a small, elegant black hat.
That same day, other members of the Imperial Royal Family attended a wake for Prince Katsura. As is expected, many wore small black hats.

Royal Hats 
They show exquisite dignity while mourning. The small hats are quite appropriate.
