Japanese shares inched higher on Monday as investors awaited election results for the country's ruling party to choose a successor to Prime Minister Shinzo Abe.

Japanese Chief Cabinet Secretary Yoshihide Suga is poised to become head of Japan's ruling party on Monday and prime minister on Wednesday, succeeding Abe, the nation's longest-serving leader.
