Kansakar, known as Kasaa among the Udaaya, are ancient inhabitants of Kathmandu.
According to the caste system introduced by Jayasthiti Malla, these people were called Kansakars for their profession with Kayan (bronze). However, they are now known as Kansakar. Kasah Tadhan Guthi is the main Guthi of Kasaa. This Guthi has three Agams (family shrines) namely Thachhen, Kwachhen, Nhunchhen, and six kawals. According to some people, the main guthi has been in operation for hundreds of year and was reformed in 1048 Nepal Sambat under the leadership of Poet Yog Bir Singh. But according to some other people, this guthi was founded in 1048 Nepal Sambat under the sponsorship of Yog Bir Singh Kansakar. Yog Bir Singh is one of the four pillars of Nepal Bhasa literature.
The main role of the Kansakar is to play Payantah (kind of long trumpet) in religious processions and functions.
There are altogether 122 Kansakar households and almost all of them have their Digu Khyo in Lumadhi.
