Japan's Prime Minister Shinzo Abe was busy selling Abenomics to world leaders in Davos on Thursday.

But Japan was also looking to find a way into leaders' hearts through their stomachs.

Cracking open a barrel of sake, Japanese representatives at the World Economic Forum in Davos treated assembled leaders to finest in Japanese cuisine.

Sushi and steak made from tender wagyu Japanese beef were among 20 different kinds of food on offer.

Visitors were also invited to write their thoughts on Abenomics and Japan on placards.

One attendee said Japan needed to stay focused.

"I think right now I feel some really good steps taking place in Japan and it's important that everybody stays focused on things that really make a difference."

Another voiced doubts on Japan's planned sales tax hike.

"Well the first word is of course inflation. The second word is consumption tax. My feeling is it was a mistake to agree to do it. But now that he*s agreed to do it, he has to do it."

People are waiting to see if Abe will be able to follow through on his strong pledges for change in Japan.
