On a very simplified level, what could Japan do to boost its slowing economy?

Question

On a very basic macroeconomic level, I am looking for ways japan could boost its economy.

Answer 1

Allow more controled legal immigration. Japan has a very low birth rate, and a rapidly aging population. Historically they have not really ever done this, but immigration does impact the economy.
Some experts believe Japanese public policy tends to favor larger corporations rather than small and medium high growth companies.
