A total of 2,473 new condominiums were listed in the reporting month, down from 4,093 units a year before, the Real Estate Economic Institute said. Of the new condos listed in Tokyo, Chiba, Kanagawa and Saitama, almost 75 percent found buyers, down 3.5 percent from a year earlier, it said.

The average unit price rose 2.5 percent to ¥48.46 million.

In Osaka and five nearby prefectures in western Japan, new condo supply fell almost 10 percent to 1,222 units, with more than 74 percent finding buyers.
