Japan’s Nikkei surged almost 8% on Wednesday in its biggest one-day jump since late 2008.
The benchmark index closed up 7.71% at 18,770.51 points. A day earlier, the index saw all the gains it had made this year wiped out.
Remarks by newly re-elected prime minister Abe suggesting company tax cuts were on the way helped the mood.
Also positive were Tuesday’s rebound for US shares and an improving Chinese share market.
Investor sentiment was up across the rest of Asia.
