Onagadori

by T. Tsujizono

Onagadori is one of the Natural monument in Japan. It is same kind of cocks, and the place of origin is Kochi. Onagadori is known as a “Yokohama” all over the world because Onagadori was exported from Yokohama. It is called other Tyobikei and Nagaodori.

Description
Onagadori was discovered in Edo period in Shikoku. It was one of the kind of cocks farmed by Riuemon Takechi who lived in Ohashimura in Tosa. One day, Riuemon found that one of the cocks had very long tail. That is a mutation where the feather doesn’t come off. Regular cock’s feather comes off once a year. That is very conspicuous, so Onagadori was sent to Edo government about that time. It is said that the Tosa clan concealed the Onagadori at first because the Onagadori had a very valuable, long tail.

Culture
Onagadori’s tail grows about 1 meter every year but it comes to grow slowly whenever aging. Onagadori’s tail length is about 7 meters. In Meji period, that length was about 3 meters but Tomebako was developed in Taisho period to let the tail grow longer. Tomebako is a device to control movement and stop tail damage. Today, the Guinness book of Records says longest tail is 10.6 meters.

Conservation
The natural monument was specified on March 7, 1923, and Onagadori was specified by the special natural treasure on March 29, 1952. This is because of being specially recognized in worldwide or the nation assuming that value is especially high.

Viewing
When coming to Kochi Prefecture, please see Onagadori by all means. A white, long tail has a beautiful, strong sense of existence. We should protect Onagadori.

  1. I understood the special means that Onagadori comes to Kochi .
    I was impressive that Onagadori’s white and long about 7 meters tail has a strong sence of existence.

  2. I know Onagadori. I had seen only on the TV. It is like cock, but it has very long train. According to this article, Onagadori’s train length is about 7 meters. I wonder if the Onagadori thinks it to be obstructive. I was surprised at “Onagadori’s train grow about 1 meter every year but it comes to grow slowly whenever aging.” And “Today, the Guinness book of Records says longest train is 10.6 meters.” I want my hair to grows fast similarly. I came to like Onagadori reading this article. I want to see the real Onagadori once.

  3. I would like to know that the tail can grow indefinitely. I knew that onagadori is same kind of cooks for the first time.

  5. I have seen Onagadori on TV.
    I have known it since I was a junior high school student, but I didn’t know that

    In the past it was a farm animal,but it isn’t a simple farm animal.
    I think its train is useless,but I think its train is beautiful.
    Is its train need?
    I think its train is used courtship behavior and its females like male’s long train.
    The other my opinion is its train is become long by human.
