Japan is interesting because it has the highest debt-to-GDP ratio of any developed country and most other countries in the world are increasing their debt-to-GDP ratio; in effect, they're all moving towards a Japanese reality due to the fiat system's lack of hard monetary constraints.
If you look at Japan, the aspects of its economy and society which stand out the most are:
- Rigid economic structure and processes.
- Economy dominated by huge corporations, without much room for startups.
- Highly concentrated urban population.
- Population decline. Many young people are not dating and not getting married, can't afford much on their salaries working in the city.
