yes and no. youre right that japan is overpopulated by ethnic japanese. but comparing it to african countries, the difference is their age gap. there are more young people in africa than japan and japan has more old people than their young people. you may think that when the japanese boomer dies, they return to their golden age of repopulation but no. the young ones in japanese will become the new boomers that will ruin the country over and over again. its the nation has this mental illness that is like hereditary. i dont know if its their school or their work or their society.
