Royal Hats 
I like these roundup posts. What would the Imperial Royal Family do without their Princesses! As always I love to see what Princess Hisako is wearing because she has so much variety but I really like Princess Nobuko’s navy tam.
The Imperial Household really gets their money’s worth out of Princess Hisako! She is constantly on the go and always has fun hats, even if I’m not a fan of every single one.
Overall this is quite an impressive roundup! If I counted correctly, this is 35 hats, which comes to roughly 1 hat every other day in the past 2 months. And while many of these hats aren’t necessarily exciting, they do look to be well-made and are meant to be working hats, so they can’t be too extravagant.
Thanks HatQueen for not forgetting the Japanese and giving us so many hats to admire!
I would agree with the other commenters that the Princess Takamoto (Hisako) has the most interesting hats. Lots of variety in shape, colour, trimmings, and texture. And always worn with a delightful verve.
Many of the other hats are very elegant but of a type. All appear to be beautifully made.
The current Empress and the new Queen Consort seem to be two hat wearers that find successful styles but are then hesitant to expand their repertoires. They would be smart to look to some of their more adventurous family members.
Quite a beautiful assortment of hats. The only one I don’t really care for is Princess Akiko’s ecru cloche, and it’s ok also. More vibrant, saturated colors are more to my liking on all these lovely Royals. Their clothes are magnificent – elegant and classic in detail.
I am so thankful for Hisako and Nobuko! If it wasn’t for them we wouldn’t have as much variety in this post. It seems to be the older Royal ladies that are willing to be more adventurous with their hats instead of the younger ones. I would like to see an a more detailed picture of Nobuko’s percher pillbox hat. It looked a little small on her head. I liked Hisako’s colorful hat band at the beginning of this post and her homburg with pumpkin/chocolate twisted hatband. I also adore the fuchsia hatband on Kako’s hat and her fuchsia suit! Yoko’s blue hat looked beautiful, too. Most of the hats are just a question of which neutral color it is, the color of the hatband and whether the brim is upturned or flat!
I adore Princess Takamado’s quirky sense of style – it looks like she is having great fun choosing her hats.
