This article examines the feasibility of using role identity as an independent variable to explain the direction of a state’s national security policy. Focusing on the response of the Japanese government to the Gulf War (January‐March 1991) and the U.S. War in Iraq (March‐May 2003), the article correlates articulations of their preferred role made in the Japanese Diet, with these policy outcomes. It finds that the different balance of role conceptions held by Japanese politicians in the two periods under study can explain the difference in policy outcomes. The study also finds, however, that the salience of these role identities is directly affected by contextual factors. Under circumstances of heightened threat perception, Japanese policy makers were less inclined to articulate any sort of value‐based role identity for Japan in favor of role statements that were characterized by pragmatism.
How do politicians motivate voters to turn out and support them? We posit that incumbents construct tournaments between groups and distribute rewards to groups based on the levels of electoral support provided. We test our propositions in Japan, where incumbents can discern relative levels of support provided by municipalities in their districts and influence spending in ways that reward certain municipalities over others. Using new data on approximately 3,300+ Japanese municipalities in 1980 to 2000, we show that when municipalities are ranked according to their levels of support for Liberal Democratic Party winners in their district, those at higher ranks get larger rewards, the difference in size of the reward increases at higher ranks, and those in districts where municipalities vary more in size also receive larger rewards. Our findings support the theory and help explain other features of Japanese politics, including why pork tends to flow to relatively unsupportive districts.
