No country can really said to be predominantly Taoist or Confucian in the sense that a majority of people claim one of these systems as their religion. But Taoism and Confucianism (mixed with Buddhism) are major cultural and philosophical influences in many East Asian nations. Religious Taoism in still very significant in Taiwan.
Many writers have noted that the influence of Confucianism is felt more significantly in present-day Japan than Buddhism, Shinto, or any other religion, even though no Japanese people cite it as their "religion." The majority of Chinese are influenced by combinations of Confucian and Taoist thought, and traditional religious practices and beliefs (ancestor- and nature-oriented), but most do not name themselves exclusively as adherents of these traditions. Other important influences and religions in China which are of non-Chinese origin are Buddhism, Communism, Islam, and Christianity.
Confucianism is based mainly in China, having derived its name from the teachings of Confucian, also known as Kung-FY. In the 6Th Century BC. It is not exactly a religion. It is a philosophical system who co-existed in China and Japan, along with Taoism and Buddhism. It preaches the ethics and the ritual to be observed on occasions like child-birth, death etc. It lay emphasis on the duties and discipline cast on the children towards the parents and the elders. It preaches the ethics to be followed by the rules for the protection of the subjects. It co-existed with Taoism and Buddhism in those time. In the modern day China and Japan, the influences of all these three systems on the people can still be seen.
It is emphatically not a religion, despite its being presented in that manner by Portugese missionaries during the 16Th century -- individuals who very badly wanted to believe that a "Prestor John" figure had Prue-figured Christian morals in China. Kung Tzu was a philosopher, not a prophet, and his teachings bear none of the hallmarks of a religion (e.g., belief in and submission to a divine being). Read "Inventing Confucianism" by Jensen if you would like the actual history instead of the silly fables you have apparently been given.
China. Confucianism is a Chinese ethical and philosophical system originally developed from the teachings of the early Confucius. Therefore it is not a religion...it's just a way to better life.
Of which country is Confucianism a native religion?
