Japanese: ‘long rice paddy’; from a common place name. The majority of bearers today are descended from the Sasaki branch of the Minamoto clan, and took the name from a village in Ōmi (now Shiga prefecture). Listed in the Shinsen shōjiroku, the characters are pronounced Osada or Chōda by some families. All three versions are found in eastern Japan. The name is also found in the Ryūkyū Islands.
