My study investigates whether there has been a relative decline in the position of the Japanese bureaucracy in their relationship with politicians in recent decades. My hypothesis is that the loss of bureaucratic influence has been a function of the declining position of former bureaucrats within the ruling Liberal Democrat Party (LDP), and that politicians who were able to enter the Diet at a young age (due to hereditary recruitment) have gained influence. Their seniority has placed them at an advantage in promotion to key party and government posts. I use probit and logit analysis of LDP cabinet and Diet members (1955–2003) to demonstrate the decline of former bureaucrats within the LDP in terms of their overall numbers and their occupancy of key posts.
