The community redevelopment group purchased the Doll House in 2014 and the former bank in 2015 with plans to revitalize Hamilton Avenue. Walsh said the group approached Harada last winter about opening a restaurant in College Hill.
"We were originally trying to convince Kaze to move up here," Walsh said. "We showed Harada around. He fell in love with the National City Bank building."
Harada, who opened Kaze at 1400 Vine St. with business partners in 2012, left the Over-the-Rhine eatery in March. The new Japanese restaurant is not affiliated with Kaze, Walsh said.
The group also approached College Hill resident Omar Garcia last winter about opening Tortilleria Garcia into the Doll House space. Garcia and a business partner opened their fast-casual Mexican restaurant at 11774 Springfield Pike in Springdale in 2014.
"We realized College Hill residents wanted a neighborhood Mexican restaurant, and the owners fell in love with that location," Walsh said.
Interior rehabilitation of both buildings is set to begin in December, he said.
The restaurants will join Brink Brewing Co. in the growing Hamilton Avenue business district. The craft brewery opened at 5905 Hamilton Ave. in February.
