Mobile marvels keep Japan ahead of times

In the Japan of 2020 a stressed-out salaryman may unwind from his hectic futuristic lifestyle by time-travelling back a few centuries and taking a virtual stroll through medieval Tokyo.

As he walks over arched wooden bridges, he will chat with the avatars of his real world friends, admire pollution-free views of Mount Fuji and perhaps do some cash-free souvenir shopping for a digital download of a woodblock print.

Welcome to the future as imagined by NTT DoCoMo, Japan's mobile telephone giant with 55 million subscribers, which has long been a leading force for innovation in the high-tech paradise that is Japan.

Its Shangri-La is the "Future Station", located in a skyscraper 29 floors above Tokyo, where visitors are taken on guided tours of the company's mobile phone marvels, and treated to a glimpse of what's to come.

Such as the wearable phone of 2020 that DoCoMo envisions will be the user's constant companion, fitted with a small flip-out screen and capable of projecting images onto a wall or into thin air in the form of a hologram.

It will be an ID to enter the family home or to board a flight, a device to video-chat with friends and the office, and a remote control to activate the robo-vacuum cleaner or tell the fridge to order new groceries.

Made from recyclable materials and partially charged kinetically through body movements, the device will be equipped with simultaneous translation software to connect the user to everyone else, anywhere, anytime.

The vision is bold, but in Japan that doesn't make it unrealistic.

In many ways the mobile phone future has already arrived in Japan, where the evolution of the devices has taken a separate path to the rest of the world.

On Tokyo's crowded subway trains, newspapers are a rare sight as most commuters plug themselves into their cellphones or other handheld electronic devices – web-surfing, mailing, playing games or watching television.

Japanese mobile phones started sending e-mail 10 years ago, have had terrestrial TV for years and long boasted video cameras, barcode readers and an 'i-concierge' assistant that gives hints on a late train or a traffic jam.

DoCoMo's phones since 2007 feature a cashless payment system, which allows users to buy a soft drink from a vending machine or lunch at a hamburger chain, simply by swiping their phone over an electronic pad.

"By having a phone you can do almost everything," said Takeshi Natsuno, known as the 'father of i-mode', the popular internet service DoCoMo launched a decade ago, and now a professor at Tokyo's Keio University.

"All convenience stores and 60 per cent of Tokyo taxis are equipped with readers so you can pay by phone," he said, adding that this is one reason the central bank three years ago started to reduce the number of new coins minted.

DoCoMo co-develops phones with manufacturers such as NEC, Fujitsu and Panasonic, who then custom-make the handsets for it. Usually the makers are identified only discreetly with their initials in the model name.

Among recent offerings is the bright-yellow Kids Phone F05A by Fujitsu, which features a pull-string alarm that emits a shrill noise and sends an email alert to the parents that instantly pin-points the child's location.

In another new model, the two halves of the phone are held together magnetically and can be easily separated, allowing users to talk and web-surf at the same time, or to split the device into a TV and a remote control. Other newcomers include a cellphone with a small solar panel that in a pinch can give the user a few extra minutes of power, a phone with a 10-megapixel camera, and a range of waterproof models to use in the bathtub.
