Inside decades-old school buildings in Shinjuku Ward, Tokyo, that had been used by Waseda Jitsugyo High School until a year ago, university students and entrepreneurs work around the clock to realize their dream of launching successful startup businesses.

Some people bring their own computers and other high-tech equipment into the former classrooms, now equipped with air conditioning, a local area network and cable television lines.

Some have brought their own bedding to sleep in the "offices," while others installed a refrigerator and a blender to develop fresh health drinks as potential products.
