One key advantage is stability. Since the Japanese government remains the largest stakeholder, the business tends to be stable and risk-averse, which can be a plus for long-term planning and job security.
Cons
However, this stability often comes with a rigid bureaucracy. Career progression tends to be based more on seniority than on individual performance or merit, and opportunities for significant promotions or compensation increases are limited.
With its rigid organization, precedent-setting approach, and gloomy internal atmosphere, this company seems to boil down all that is wrong with Japan.
Cons
I hope that the company will break with its political affiliations, act with integrity toward consumers and employees, and restore itself to what it should be as a living infrastructure for the community.
