Can Kansai people in Japan understand their dialect?

There are many dialects in Japan, but Kansai is the easiest to understand. It’s very much like Beijingers listening to Northeastern dialect.

The truly difficult to understand dialects of the aboriginal people of several northeastern Japan prefectures, Hokkaido and Okinawa. These places were places of alienation in Japan in ancient times.

For example, the Iwate Prefecture dialect in the TV series "Ama". That one is so funny.
