A total of 28 prefectures saw affordability of brand-new apartments worsen in 2017, up from 22 prefectures in 2016.

Tokyo’s 23 wards were the most expensive across all regions in Japan with 70 sqm brand-new apartments costing 13.26 times the average annual income and 10-yr old second-hand apartments costing an average of 10.46 times the annual income. The multiple for brand-new apartments increased by 0.19 points from 2016, while the multiple for second-hand apartments increased by only 0.05 points. The widening gap between brand-new and existing apartments is causing consumers to switch their attention to the more affordable existing home market.
