The very idea of big-spender Shinzo Abe's reappointment as prime minister was enough to send the yen falling against the dollar and spurred the Nikkei above the 10,000 mark for the first time in months.
Now that Abe's reascension is official, market players are eager to see if his actions will live up to his words.
"Abe's moves have stimulated the market, especially the strategies he has put forward that signal more economic growth," Takuya Takahashi, a senior strategist at Daiwa Securities, said in a lecture delivered earlier this month. "Overseas investors have high hopes for Abe as well," he added.
