Your ignorance is showing.

Do you know that Korea faces the serious concerns of rapid aging and very low birthrate than Japan?

Why does Korea run a substantial trade deficit (25 billion-dollar) with Japan?
Because key components in Korean products is almost made in Japan.
Most manufacturing machinery is made in Japan.

They have no inventiveness and creative technique.
Korea's patent royalty is 5.8 billion-dollar in deficit.
(Japan's patent royalty is 7.9 billion-dollar in surplus)
Korea just import components from Japan and assemble them.
And they sell them cheaply without any thought of gain to increase one's market penetration.
Additionally, they commit a lot of serious patent violation.
SAMSUNG is sued by many patent infringement.(more than 3800 cases)

Incidentally, Samsung is 60% foreign-owned company.
LG is 50% foreign-owned company.
Almost Korean company and bank is taken over by foreigners.

Now, Japan have the strongest currency in the world.

Japan is the richest country in the world for the foreseeable future

The Japanese government recently signed with the International Monetary Fund on to provide $60 billion in emergency loans to the multilateral lender amid the global economic downturn following the sovereign debt crisis in Europe. Other Asian country lie China and Korea do that because they are not true rich countries. In fact, Korea's financial crises over the last decade have been saved by Japan.
