Japanese government made a big mistake by injecting a little bit of money again and again in the past 20+ years, it didn't work- because Yen kept on going up!
Now, the new prime minister (Abe) realizes Japan needs to follow US and Europe by injecting unlimited amount of money (printing money) to stimulate the economy.
It will work because its currency (Yen) will devalue. Unless the problem with China gets worse, Nikkei should double and banks should triple in 1-2 years.
It is true, a 22-year downturn has accumulated a lot of upside potential. If everything goes smoothly (Yen, China relationship etc.), major Japanese banks can go up 5-10 times.
