The number of condominiums put on sale in the Tokyo metropolitan area in March rose 13.4 percent from a year earlier to 7,596 units, the first year-on-year increase in five months, the Real Estate Economic Institute said Wednesday.

The marked increase was driven by high-rise and large-scale condominium complexes, an official at the institute said, adding that they are selling well partly due to growing expectations of a pickup in the economy.

The institute said 83.6 percent of new condos in the Tokyo area found buyers. Per-unit prices averaged 42.09 million yen, up 7.6 percent from a year earlier, with the price rising 6.5 percent to 554,000 yen per square meter, the Tokyo-based institute said.
