One recent innovation is "hitori yakiniku". Meaning "grilled meat", yakiniku usually involves sitting around a gridiron at a restaurant table with a group of people and communally cooking mountains of chicken, beef or pork. But with ohitorisama, the only one grilling (and eating) all that meat is you. Even karaoke is going solo – a huge change to the classic Japanese pastime. "Demand for single-person karaoke has increased to account for 30 to 40% [of all karaoke customers]," says Daiki Yamatani, a sales manager who does PR for the 1Kara solo karaoke company in Tokyo. In Japan, karaoke spots are everywhere, often big buildings with several floors of private karaoke rooms built for groups of various sizes. But demand from solitary singers has been growing, and so 1Kara swapped large group rooms for phone booth-sized personal recording studios.
