Meaning

Disparity or gap, especially the wealth gap and economic inequality between social groups.

A word that defined Japan's social debate from the mid-2000s. 格差社会 (disparity society) became a buzzword describing how Japan's formerly egalitarian middle-class society was splitting into haves and have-nots. The discussion covers income inequality, educational opportunity gaps, regional economic disparities, and generational wealth differences. It challenges Japan's self-image as a classless, homogeneous society.

Examples

1. 年収の格差がどんどん広がってるのに政治家は危機感がない。 The income gap keeps widening and politicians don't seem to feel any urgency about it.
2. 教育格差って親の経済力で子どもの将来が決まるってことでしょ。 Educational disparity basically means a child's future is determined by their parents' financial status, right?
3. 都市部と地方の格差はもう限界に来てると思う。 I think the gap between urban and rural areas has reached its breaking point.
