TOKYO – Hopes are high in Japan Inc. for the new prime minister. Stocks are recovering. The central bank is set to supercharge an already loose monetary policy. The soaring yen, a big minus for exporters, is reversing course.

The bullish mood in the air is all about “Abenomics” — a reference, as dubbed by experts and market players, to Shinzo Abe, the shoo-in comeback prime minister when Parliament votes next week.
