The Chinmoku Clan was started by Ryuunosuke, a strong warrior from a small country (it hadn't gotten it's name yet). Ryuunosuke was in a fight to save a princess, when he meant her nurse, Asami. Asami was a very smart woman with a very soft heart. Ryuunosuke fell in love with Asami and married her. The princess was furious because she loved Ryuunosuke, so she began to plot things to wreck the marriage. Many failed and during the marriage, they had four sons and two daughters. When their fourth son began to train to become a ninja, he began to get interested in sound technique. Their son was the first carrier of the Kekkei Genkai.
The most common characteristics of a Chinmoku is dark eggplant color hair and/or grey eyes. They are most commonly quite pale. The women are noticably shorter than average, where the men are actually taller.
The unnamed Kekkei Genkai of the Chinmoku is a genjutsu having to do with munipulating the sounds of what happening around the opponent, making it seem like someone is saying something to them. It can range from what the Chinmoku will say to the opponent. They often make it battle orders from a team member with, so the opponent will come at the Chinmoku in a way that they will counterstrike in a way that can cause serious damage to the opponent.
The only sign of the Kekkei Genkai is that the iris and pupil of the Chinmoku will be the Clan symobol.
Many of the Chinmoku in the in history were loyal to to their place of origin, the Country of Rice Fields. But, ever since Orochimaru founded the Sound Village and the people of the Country of Rice Fields are expected to be evil, the last Chinmoku live in Kumogakure. The Chinmoku that live there do not wish to live in Otogakure, even though it's where their clan was loyal to for many years.
- Though there must be more Chinmoku for the clan to have been able to flourish, the only mentioned Chinmoku are the first two and their six children and the last three.
- At the Chuunin Exams, there were two kids, a boy and girl, with the Chinmoku characteristics and it's suspected that it's Kazuko and Daisuke.
- Kazuko and Daisuke have slightly tanned skin because their father was presumed to be quite tan, even though many Chinmoku are very pale.
