Those who are interested in the East Asian region might remember the considerable controversy over a history textbook published in 2005 by the Atarashii Rekishi Kyokasho wo Tsukurukai (Japanese Society for History Textbook Reform; hereafter, the Tsukurukai). Their history textbook was strongly denounced for glorifying Japan's wartime conduct and gave shocks to inside Japan but throughout East Asia, especially the neighboring countries. In response, researches on the Tsukurukai have exploded. Previous literature focuses on how the movement driven by the Tsukurukai is reflected in nationalism in Japan and its influence on foreign policies and international relations; there are relatively few empirical studies of the Tsukurukai per se, including on the Tsukurukai's networking with politicians. Although many activists and scholars have pointed out the connection between the two, empirical researches on the relationship are understudied. This paper aims to analyze the history issue related 'conservative group,' the Tsukurukai, and its networking with politicians from the interest group politics perspective. More specifically, this paper borrows the framework of lobbying venue selection of interest groups. Social groups, in order to achieve their goals, strategically choose a lobbying venue, primarily either politicians or bureaucrats. In this process, the presence of like-minded friends, political environments, and accessibility influence on the decision of interest groups. This paper thus focuses on the Diet Members Group(DMG). Put differently, this paper argues that conservative groups tend to choose politicians as a lobbying venue because this DMG provides the high accessibility to civil groups for networking. Specifically, the study meetings (benkyokai) that DMGs hold play a substantial role; that is, it is where members of relevant groups and politicians share and formulate their preferences. To support the argument, this paper analyzes the "contents of the benkyokai" Finally, this paper intends to contribute to academic discourse on Japanese interest group politics in terms of interest groups' lobbying venue selection and its position in Japanese political process, and enhancing understanding of controversies around the Tsukurukai and their movement in the region.
