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)
The Second World War is certainly the most tumultuous time in Japanese history but it was still an era of relative stability when compared to civil wars, revolutions, and invasions in most parts of the world E.g. the monarchy prevails
2) He's right. Japan post-WW2 endured foreign occupation yes, but without significant internal turmoil. Other states that underwent massive change (e.g. Russia: WW1->Civil War->2 Revolutions) had significant internal turmoil. This helps explain why so many "old" businesses survived in Japan.
