**Minyou** traditional Japanese style singing

[AsahinaKimi]

Min'yo is a genre of traditional Japanese music. The term is a translation of the German word "Volkslied" (folk song) and has only been in use during the twentieth century. Japanese traditional designations referring to more or less the same genre include "inaka bushi" ("country song&quot "inaka buri" ("country tune&quot , "hina uta" ("rural song&quot and the like, but for most of the people who sang such songs they were simply "uta" (song). Many min'yo are connected to forms of work or to specific trades and were originally sung between work or for specific jobs. Other min'yō function simply as entertainment, as dance accompaniment, or as a components of religious rituals.

This is called Ondo
Part of the Japanese Obon celebration involves participating in the local community dance. The tradition of the Bon dance, or Bon Odori dates back a few hundred years, and it is usually accompanied by the local tune. In recent times, however, new music has been used for Bon dance accompaniment, including late enka hits, and new music written specifically for bon dancing. The "ondo" rhythm has always been common in Japanese folk music, but even the newer music written for Bon dances has been written in this style. It is so common to find names of newer music with the word "ondo" attached to it.
