Maki Takashima comments

The trend of outflow from Tokyo will increase remarkably in the near future, but it's not now. I think it is a temporary reaction to people protecting themselves from the life-threatening pandemic. A heightenedawareness of danger in people's minds always causes a situation to become very fluid.

While, an awareness of working style has apparently changed from before Covid-19, some employers have a poor understanding of remote work and few leaders can easily get accustomed to it. Having said that, I believe that the necessity to stay in Tokyo will decrease gradually. After most current leaders have resigned or retired,  the people who are "Generation Y" become leaders and Tokyo will be completely changed.
