What makes Japan's synchronized dance culture so astonishing?

In summary, Japan is known for its synchronized movement, even among young children. The country's dedication and hard work can be seen in their performances, such as the Butoh dancing which is unique to Japan. In addition, the Japanese culture promotes a fluid interaction between genders from a young age, unlike the more segregated approach in the US.
