The results of coming local elections in Osaka and Aichi prefectures could have a great impact on the shape of Japan's local government. The people concerned need to carefully watch and consider the moves of two men — Osaka Gov. Toru Hashimoto and Nagoya Mayor Takashi Kawamura.

Mr. Hashimoto has the idea of dissolving the Osaka city and integrating the Osaka city and prefectural governments into a metropolitan government similar to Tokyo's. He hopes to create a top-down system with power concentrated on the head of such a metropolitan government in order to eradicate overlapping administrative actions between the Osaka city and prefectural governments and to buoy the local economy. Osaka Mayor Kunio Hiramatsu vehemently opposes his idea.

In April 2010, Mr. Hashimoto launched a local party called Osaka Ishin-no Kai (Osaka Restoration Association), which will concentrate on local politics within Osaka Prefecture and will refrain from seeking seats in the Diet. As a first step to establish a political foundation to follow through with his idea, he plans to control both the Osaka city and prefectural assemblies. His party will run more than 100 candidates in local elections in April to elect members of the Osaka city and prefectural assemblies and the city assembly of Sakai in Osaka Prefecture.
