Osaka 10th district

Ōsaka 10th district (大阪府第10区, Ōsaka-fu daijikku or 大阪10区, Ōsaka-jikku) is a single-member electoral district of the House of Representatives, the lower house of the national Diet of Japan. It is located in North-eastern Osaka and consists of Takatsuki city and Shimamoto town, the only remaining municipality of Mishima county. As of September 2012, 315,999 eligible voters were registered in the district.^[1]

The current Representative for Osaka 10th district is former Liberal Democrat Kenta Matsunami. In 2012, he ran for the Japan Restoration Party of former Osaka governor Tōru Hashimoto that won twelve district seats in the prefecture. The previous incumbent, Democrat Kiyomi Tsujimoto, had been elected for the Social Democratic Party in 2009, but left in 2010 after disagreeing with her party's departure from the Democrat-led ruling coalition.

Before the electoral reform of the 1990s, the area had been part of the five-member Osaka 3rd district.
