Another point I want to mention is that Japan was never invaded on its own territory by a foreign power and it wasn't ruled or politically influenced by outsiders for many centuries. This helps a lot to build and preserve a business.

On the contrary if you take the Balkans in Europe every few centuries the ruling power changed. First was the Roman Empire, then the Byzantine Empire, Bulgarian Empire, many other nations come to power for different periods, then the Ottomans, the Soviet Union and in the present day most of the companies and corporations in the Balkans are very proud if they have a history of 20-30 years (after the collapse of the Soviet Union)
