TOKYO—Tokyo somehow managed to squeeze in five more residents Monday, when the Takashi family moved into a converted studio apartment. "This was a one-bedroom apartment housing a family of six, but a wall was cleverly constructed to create a small studio," city planning minister Hideki Kumagai said. "This was good: We rarely can fit new citizenry into our city without drilling into the bedrock." The Takashi family, brought in from Osaka's overflow, will pay the equivalent of $12,600 monthly for 144 square feet of living space.
