A Look At the High-Tech Future of Japan

Space tourism, artificial organs, and butler ’bots--these are Japan’s forecasts of its future

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.

2020 - Thin, flexible electronic displays replace newspapers.

2022: Synthetic Blood

2022 - Synthetic blood makes donation unnecessary.

Cancer in 2023

Cancer cells are best identified by internal details, but research with a scanning electron microscope can show how cells respond in changing environments and can show mapping distribution of binding sites of hormones and other biological molecules.iStock

**2023 ** - Doctors use medicine to control any cancer.

2025 - Electric cars travel 310 miles on a single charge.

With continued improvements to the energy density of lithium-ion batteries, 310 miles will be "feasible by 2018, and very doable by 2025," says Donald Hillebrand, the director of transportation research at Argonne National Laboratory. In 20 years, though, lithium-air batteries, in which lithium and oxygen react to generate electricity, could produce five times as much energy as a lithium-ion battery of similar mass.

2026: Domestic Humanoids

2026 - Domestic humanoids become common.

2033 - Stem-cell techniques can produce artificial organs.

At the Wake Forest Institute for Regenerative Medicine, scientists have made a transplantable artificial bladder and are working on 22 human tissues and organs, says director Anthony Atala. His group has made nickel-size working hearts, but it could take decades to make sure all new organs can safely integrate into the body.

2031: Orbiting Earth

2031 - Earth-orbiting space sightseeing tours go on sale.

2030 - A.I. is able to form opinions on movies, books and art.

2028 - Smellovision—televisions that produce tastes and smells—grace every living room.

2033 - Computers evaluate policy recommendations and institutional plans.

2035 - Commercial flights are 100 percent autopilot.

The software will be ready in 5 to 10 years, says Michael Toscano, director of the Association of Unmanned Vehicle Systems, but we'll probably never see an unmanned JFK–LAX flight. Although the Federal Aviation Administration's Next-Gen air-traffic-management system will switch planes to satellite navigation, which could help control autopilot systems, the FAA currently says that commercial flights will always be human-flown.

2035 - Scientists extract uranium and other rare elements from seawater.

2037 - Seismologists can predict earthquakes above a magnitude of 6 up to a year in advance.

2040 - Earthlings establish a manned lunar base.
