CHIBA — Prime Minister Naoto Kan was rumored Thursday to have two key changes in mind for his looming Cabinet reshuffle, sources said.

One will replace Chief Cabinet Secretary Yoshito Sengoku with his Democratic Party of Japan's deputy secretary general, Yukio Edano.

The other will appoint Kaoru Yosano, who left Tachiagare Nippon (Sunrise Party of Japan) earlier in the day, to a new Cabinet post in charge of social welfare or tax reform, or a post as Kan's adviser.
