Yuutaro Oono was born  in Tokyo in 1935. He is currently the CEO of Ohno Seimitsu Kogyo Co. Ltd.
     After graduating from Hokunoujima Technology High School, Mr. Oono was employed by an 8mm film company. In 1978, he started Ohno Seimitsu Kogyo Co. Ltd which specializes in making gears. He also dedicated himself to bringing back Karakuri dolls , which were popular in the Edo period, to modern times, using the advanced techniques of  modern  gear making.
     Mr. Oono first learned about Karakuri in an engineering book and he became passionately interested in them.  He had acquired a copy of “Karakuri-zui”, an illustrated compendium of mechanical devices written by Hanzou Hosokawa, a legendary karakuri artisan of the Edo period. Mr. Oono began studying the book intensely and, for the last 20 years, he has been reproducing the Karakuri dolls most loved by people in the Edo period such as “tea serving doll”, “shinan guruma” and the “Karakuri clock”.
     Each doll is made using about 80 different parts, not counting its face and clothing.  The dolls are created in such a way as to preserve traditional methods as much as possible. The fusion of the Edo period and modern times shows both beauty and functionality.
     Mr. Oono’s next project is to bring back “Yumihari Warawa, or “ Boy Archer”, which shows  a boy shooting an arrow at a target. His tremendous respect for  the Karakuri artists of the Edo period motivates him to try to recreate the Karakuri Dolls most beloved in that period, so that people can remember and appreciate their heritage.

The word Karakuri was used to describe traditional Japanese mechanical devices. In the Edo period especially, gears from clocks were first used to make moving dolls and the elaborate Karakuri doll tradition began.
  It was Hanzou Hosokawa from the Tosa region who first revealed to the general public the way the Karakuri work, using easily understood illustrations. His book, Kkarakuri-zui, had a tremendous impact on many artisans who later developed their own techniques in the field.  This book is considered to be the foundation of Japanese robotic technology.
In the 20th century, acrylic resin was invented and the Karakuri techniques were handed down to Yuutarou Oono.  Mr. Oono not only successfully revived Hosokawa`s Karakuri but,  in a similar spirit of openness, he made them out of transparent acrylic.  It is exciting to see a doll in a beautiful kimono bringing and serving tea but people were doubly delighted to to see the dolls’ inner workings as well. The transparent gears developed by modern technology allowed this to be possible.
It is the spirit of true Karakuri artists to honor the people’s desire to know and also create such beautiful dolls that are totally in keeping with the Japanese people’s sense of esthetics.

Karakuri Ningyo or Karakuri Dolls are traditional mechanical dolls of Japan.
“Karakuri” means a mechanical device to amuse people and they were originally found in China around 10th century. Karakuri Dolls are said to have been introduced to Japan in the Muromachi period.
In the Edo period, the gear mechanisms used for clocks began to be used to make moving dolls and the production of Karakuri Dolls began.
At first, they were made as toys mostly for the upper class. They gradually became a popular attraction at amusement parks and widely seen in all over Japan.
In 1662, Oue Takeda began a touring  Karakuri-Doll-theater, something unique at the time and during the Kyoho period (1716~1735), Karakuri Monya, using the best Karakuri techniques then available, made a four-wheeled vehicle that was propelled by pedaling.
At the end of the Edo period, Hisashige Tanaka, known as Karakuri Giemon, created “Yumihiki Douji” (the Boy Archer), which is regarded the highest standard of  Karakuri dolls made in Edo period.
Karakuri dolls are traditional Japanese precision machines considered to be the foundation for today’s industrial robots.

Obake no Kinta or Kinta the Ghost is a folk toy that originated in Kumamoto City, Kumamoto Prefecture.
The toy consists of a head with a string in the back of it.  When the string is pulled, Kinta rolls his big round eyeballs and sticks out his tongue.  A bamboo spring is concealed in his head which, when pulled, triggers the eyes and the tongue to move at the same time. Kinta with his red face and a black conical hat makes a striking impression on small children and he often scares them a little.  He is a popular toy among adults, however.  The most important process in making this toy is the making of the bamboo spring.  The quality of this spring determines the quality of the toy.      
When Kato Kiyomasa built the Kumamoto Castle, there was a popular foot soldier named Kinta who had a funny face and who was good at making people laugh. He was affectionately called “Clown Kinta”. The Kinta the Ghost toy was said to have been created during the Kanei era (1848 ~ 1853) by a doll maker, Hikoshichi Nishijinya, who started making mechanical toys based on stories about Kinta.  Because of his unique action, Kinta the Ghost was also known as the Goggle-eyed Doll.

Hishio Festival held in early May at Kamizaki Shrine in the Kamezaki district of Handa City, Aichi Prefecture, has a long history. One theory states that it dates back to the late 15th century, but its origin is unknown. It is a nationally designated Important Intangible Folk Cultural Property.

Five festival floats, all of which were constructed in the late Edo period (the 19th century), are pulled down to the beach in front of the shrine when the tide ebbs, which originates in the legend that the enshrined deity landed on this village from the sea; hereby it was named “Hishio,” meaning “low tide.”

The floats are then pulled up to the bank of the beach and stand closely side by side. The line of gorgeously decorated floats looks very impressive. After the Karakuri doll performance, which is solely seen in the areas around Chita Peninsula, is done on the upper story of the floats, they are pulled around the town.

As the wheels of the floats are removed and buried in the sand of the beach after the festival to prevent corrosion, the preparation of the festival starts with digging them out, which is followed by assembling of the floats, Ohayashi music practice, and so on. It takes more than one month to prepare for the festival.

Iris Festival is held from May 25 to June 20 every year in Chiryu Park, the outer garden of Chiryu Shrine. The Japanese irises in this park were donated by the imperial Meiji Jingu Shrine in 1955, 1957 and 1960. Sixty different species of irises that were loved by Emperor and Empress Meiji come into flowers during the festival. The best time is around June 10, when visitors can enjoy viewing gorgeous and colorful flowers of about 30,000 stocks of iris.

During the festival period, various enjoyable events are held in the park, such as the children’s sketch contest, the photo contest of the iris flowers, the demonstration of Karakuri dolls, tea ceremonies, the tanka poem contest and the exhibition of the shrine treasures.

The city of Chiryu in Aichi Prefecture was the 39th of 53 post stations on the Old Tokaido Road in the Edo period (1603-1868). Chiryu Festival is held at Chiryu Shrine from May 2 to 3; Hon-matsuri (the main festival) and Ai-matsuri (the interval festival) are held alternately once every two years.

The main festival is famous for Bunraku and Karakuri performance and the parade of the gorgeous five festival floats, each of which is about 7 meter tall and 5 tons in weight and owned by the town within the city. The techniques of operating Karakuri dolls have been handed down since the Edo Period (1603-1868). Bunraku and Karakuri art is nationally designated as an Important Intangible Folk Cultural Property.

In the interval festival, the pretty floats decorated with colorful flowers and the children in Yakko (men servants of daimyo) costume parade through the city.

Chiryu Float Karakuri is performed at Chiryu Festival of Chiryu Shrine in Chiryu City, Aichi Prefecture, from May 2 to 3 once every two years. It is designated as a National Important Intangible Folk Cultural Property.

Chiryu Shrine is a historic shrine founded in 112 and was ranked the second largest shrine in Mikawa province in the Heian period (794-1192). The enshrined deities are Ugaya Fukiaezu no Mikoto and other three deities. The shrine is worshipped by local people as the god to prevent attacks by Mamushi pit-vipers as well as to bring rain and safe delivery.

Karakuri dolls have been made by the local people in Chiryu with creative ingenuity, and the techniques have been handed down since the Edo Period (1603-1868). They are made by the hands of the town people. The mechanism of the dolls is not sophisticated, and scrub bushes and scrap fabric are used for the material. It is unique and almost unprecedented in the way that dolls alone perform a whole play of Bunraku in response to Jorui chanting. It is said that Chiryu Karakuri is the most elaborate style of the float Karakuri in the country. It is a traditional culture that represents the pride of the people in Chiryu.
