In 21 years, vacationers will sip mojitos while watching the sun set over the far side of the planet from the comfort of an orbital hotel—that, at least, is according to a panel of 40 Japanese scientists. In June, the Japanese government released its Foresight Survey, which since 1971 has polled the country's top minds to map out Japan's advances over the next 30 years. Past surveys have made some accurate projections. In 1997 the futurists said that Internet-based phone service would exist in 2003, the year Skype debuted. They've had some misses, too: In 1992, they thought scientists would create an HIV vaccine in 2002. (Possible vaccines are only in clinical trials.) Here, Japan's future, with a few footnotes from our stable of experts for good measure.
