Household asset/saving surveys in Japan are crucial in the study of such topics as the inequality of the wealth and income distributions, the contribution of inheritances to wealth accumulation, and household saving behavior. In this paper we assess whether the samples of these surveys are unbiased representations of the population of Japanese households. We do this by systematically comparing the distribution of each variable of interest across the surveys. In general, we were able to confirm the high degree of representativeness of the surveys including the Financial Asset Choice Survey, a new national wealth and income household survey conducted by the Ministry of Posts and Telecommunications.
