Mancai (Japanese: Mancai/まんざぃぃぃぃ/Manzai) is a Japanese form of platform comedy, similar to China's cross talk. It originated from the ancient Japanese traditional performance form "Long Live" and gradually developed in Kansai. Mancai is usually performed by two people. One person is responsible for the more serious role of finding fault (ツッコミ), and the other person is responsible for the more funny role of playing the fool (ボケ). They tell jokes to each other at a very fast speed. Most jokes revolve around misunderstandings, puns and homophones between two people.

Full color originated from the long live performance of the ancient Japanese National People's Congress on New Year's Day. That is, to celebrate the New Year as a ceremony, with leaders and supporting roles as a group, wearing black veil dresses, congratulating each family in funny and auspicious language, and then beating gongs and drums to perform songs and dances. It is said that this kind of song and dance is an imitation of tap dance in the Tang Dynasty. This kind of performance was called "Long live the Millennium" in Kamakura and Muromachi era, and many folk artists appeared.
