What are the reasons for the economic crisis in Japan and South Korea?

Causes of the crisis in the Japanese economy;
1) The global economic and energy crisis (Japan did not have its own energy reserves).
2) Corruption of LDP officials
3) Lack of attention of the state and corporations to the issues of human health protection.
4) The 1992 crisis:
-the fall in the share price of many Japanese companies;
-the ruin of some banks;
-increasing political instability.
5) Difficulties in the transition to new post-industrial relations.
6) Lack of creativity in production. South Korean industry is very closely related to Japanese industry. The crisis in Japan has had a huge impact on the industry in South Korea. But, despite all this, both countries today remain among the developed countries of the world.
