A Stanford University professor has criticized Prime Minister Shinzo Abe's economic strategy, saying it will be impossible to speedily execute all of the items in his "Abenomics" policy package.

"I counted and there are at least 170 items which Japan wants to reform. Considering (there are) a lot of barriers to reforms, such as resistance from those benefiting from the current system, it's better to narrow them to a few focus areas," finance professor Takeo Hoshi on Friday told the KKE Vision 2013 symposium in Tokyo.
