Around this season in Japan, Hinaningyo dolls can be seen here and there. They are special dolls for Hinamatsuri, also called as "Girls day". They are originally and still now displayed at many family houses that have a girl in their member. Since there are antique dolls preserved at old families or museums, in recent years there held Hinamatsuri events as a special exhibitions of many museums or as town festivals.
Detail description of Hinamaturi should be referred to Wikipedia.
A few days ago, my wife and I drove around several exhibitions near our home.
First place we went was Miyoshi City Museum of History & Folklore.
Typical Ohinasama display. The standing dolls are called Ichimatsu-ningyou.
Peach flower is another symbol of Hinamatsuri.
Some Ohinasama has a palace and the emperor and the empress are sitting in the palace.
This one has a doll about to walk down steps of the palace.
Varieties of Ohinasama made in various eras were exhibited.
The next place was The formar Iwasaki Residence. The house was a residence of Ichikawa family who was a squire at the area in 18th century.
Interior is decorated with various Ohinasama for the event. Kimonos were exhibited, too. Also, many "Tsurushibina" small dolls made of cloths are hung at strings.
Some antique stuffs were displayed to show the living atmosphere of the old days.
Inside of the roof is made of woods and bamboos.
The third place was Iwasaki Castle.
