I attended an event called “Hina Doll Festival for Adults” on April 5th at the Baba Family Residence an old Japanese building in Matsumoto.
The dress code was kimono (or something pink for men), so all the women were wearing kimono.
We enjoyed tea ceremony, To-sen-kyo (a traditional Japanese game), and a concert featuring traditional music.
Kimono is now popular among foreigners and young Japanese as something that represents traditional culture.
Also, “kimono shows” are sometimes held. One show will be held at Nagano Kenmin Bunka Center (Hokuto Hall) in Nagano City by Chubu Kimono Gakuin on May 31st (from 1:00pm, entrance fee: Y1000).
