Mitsui Fudosan Co., Japan's biggest developer, is considering rebuilding an apartment complex in Yokohama after one of the four buildings started to tilt, according to a person familiar with the situation.

Kiyotaka Fujibayashi, president and chief executive officer of Mitsui Fudosan Residential Co., on Thursday explained the plans to residents, according to the person, who asked not to be named because the information is private.

Another option the company is studying is buying back the apartments from the residents at a price higher than what they had paid, the person said.
