Naoto Kan Elected as Prime Minister of Japan
2010 · Tokyo, Japan
Naoto Kan was elected as the Prime Minister of Japan, succeeding Yukio Hatoyama. Kan's election came amid political turmoil and economic challenges in Japan.
I could not find any specific historical record indicating that Japanese Finance Minister Hiroshi Watanabe resigned on February 23, 2007, due to health reasons, with notable changes ensuing in the financial administration. As of my last update, Hiroshi Watanabe served as the Vice Minister of Finance for International Affairs but was not the Finance Minister.
For accurate historical details on that date or related changes within the Japanese financial administration, I suggest consulting reliable historical records or databases that specialize in political events of Japan in 2007.
