Remodeled children's floors in major department stores are seen as a growth pillar that could help revive sales, attracting working parents who are willing to spend more on their kids.

Customer traffic has increased following changes in the way baby items are displayed, grouping them by category or children's age, rather than categorizing them by brand. New services, including Lego block courses, have also yielded positive results amid the trend of fathers becoming more involved in child-rearing.

The Takashimaya department store chain has renovated its baby item sections in six outlets since September last year. Sales at five of the six stores in the year through August have soared roughly 24 percent from a year earlier.
