Japan launches smart city

Chiba - There were gadgets and robots galore at Japan's premier electronics show this week. But one of the biggest attractions wasn't anything you could touch - an energy efficient city of the future.

For the first time, the Combined Exhibition of Advanced Technologies, better known as Ceatec, devoted one area of the show floor to selling a vision of urban life in 2020 and beyond.

The Japanese version of the so-called "smart city" exists in a post-fossil fuel world. Alternative sources like the sun, wind and nuclear power are harnessed in mass quantities.

That power is then distributed to buildings, homes and electric cars connected to each other through "smart grids," which monitor usage throughout the network to maximise efficiency.

The goal is to drastically cut carbon emissions, which many scientists believe cause global warming - ideally to zero.

Dream

The bigger dream is for the smart city to become Japan's next big export, fuelling new growth and ambition at a time when the country finds itself in an economic rut and eclipsed by China as the world's second-biggest economy behind the US.

The city of Yokohama, just southwest of Tokyo, is the site of a social and infrastructure experiment to create a smart city for the rest of the world to emulate.

Launched this year, the "Yokohama Smart City Project" is a five-year pilot programme with a consortium of seven Japanese companies - Nissan, Panasonic, Toshiba, Tokyo Electric Power, Tokyo Gas, Accenture's Japan unit and Meidensha.

"We want to build a social model to take overseas," said Masato Nobutoki, the executive director of Yokohama's Climate Change Policy Headquarters, during a keynote event at Ceatec this week.

"Yokohama is a place where foreign cultures entered Japan 150 years ago and then spread to the rest of the country."

Now, he said, it's where the best of Japan is converging, preparing for launch to the wider world. Japan certainly isn't the only country working on smart grids.

Australia has committed $100m and is developing its first commercial-scale smart grid in Newcastle, a city in New South Wales state. South Korea is embarking on a $200bn smart grid project on Jeju Island as part of efforts to cut national energy consumption by 3% by the year 2030.

China is expected to invest a world-leading $7.3bn toward smart grids and related technologies in 2010, ahead of Washington's $7.1bn in Department of Energy grants, according to market research firm Zpryme.

Reputation

Zpryme estimates that the global smart grid market will be worth $171.4bn in four years, up sharply from $69.3bn in 2009.

On Tuesday, Toyota separately announced the launch of its own home smart grid system in Japan to coincide with its plug-in hybrid cars going on sale in early 2012.

Called the Toyota Smart Centre, it calculates the most efficient way of using energy, eliminating waste by shutting off gadgets when they aren't being used and maximising the recharging benefits of hybrids, which recharge as they run.

Utilities can also be used when rates are cheapest such as overnight to heat stored water.

With competition heating up and so much business at stake, Japan is hoping to aggressively court customers overseas, especially in emerging economies, with not only its vision but also its long-standing reputation for reliability and quality.

If it's all a little hard to imagine, Nissan was offering a peek into the future at Ceatec. The centrepiece of the car maker's pavilion was a 3D theatre with a 6.9m screen giving viewers a virtual reality drive through a "near future" Yokohama.

The virtual city tour will be replicated for leaders from around Asia when they gather in Yokohama next month for the Asia-Pacific Economic Co-operation meetings.

"We need to turn talk into reality," said Minoru Shinohara, senior vice president for technology development at Nissan, which will begin selling its Leaf electric car in December.

"If all we do is talk, I have a great fear that we will be surpassed," said Shinohara.
