摘要：
We study the applicability of the q-exponential function for the distribution of family names. We mainly focus on the rank-size distribution of Japanese family names. The result supports the fact that the q-exponential distribution is relevant to the distribution of family names that is understood until now to obey power-law distribution (Zipf law).
