In this article, we examine the long-term employment in the recent Japanese labor markets, by using the microdata from several governmental statistics since the 1980s. Main findings are as follows: (i) the decline in average tenure is found only in short-tenured workers, and the average tenure for long-tenured workers, e.g. over 5 years, did not decline. (ii) Ten-year-retention rates also keeps almost constant for long-tenured university graduates. (iii) Neither one-year-separation rates nor dismissal-rates have not been changed for long-tenured university graduates. (iv) A decline in the share of long-tenured university graduates within age cohort is not found. Therefore, the long-term employment is still respected as for the employees who have continued working for a long-term, e.g. over 5 years. One characteristic of recent Japanese labor markets, the increase in short-tenured workers, is explained by the expansion of labor market itself. The magnitude of long-term employment has not been declined.
