Japanese 10,000 Yen (~$94) Gold Coin From Times Online by Leo Lewis - Japan’s high-tech rubbish dumps - the vast “urban mines” of landfill outside every big city - have grown so huge that the country now ranks among the biggest natural resource nations in the world.

Tens of millions of defunct mobile phones, discarded televisions, PCs and MP3 players conceal a “virtual lode” of hundreds of tonnes of precious metals. An even greater seam may be lurking forgotten - but not yet discarded - in Japan’s attics and garages.

According to new calculations by the National Institute for Materials Science (NIMS) in Tsukuba, Japan has unwittingly accumulated three times as much gold, silver and indium than the entire world uses or buys in a year. In the case of platinum, Japan’s urban mines may contain six times annual global consumption.

The institute’s leading urban mine expert said that if these electronics-rich treasure troves were properly tapped, supposedly resource-poor Japan would suddenly join the likes of Australia, Canada and Brazil in the top five producers of some elements.

The mines have been accumulated because of the extraordinarily high speed at which Japanese consumers replace gadgets. Of these, the 20million mobile phones replaced by the Japanese each year are especially attractive “ores” for urban miners. Only 13 per cent, about 550 tonnes a year, are recycled, with the remainder thrown away or stored in drawers and cupboards.

The circuit boards of each phone contain a smorgasboard of precious metals: in minute quantities there are silver, lead, zinc, copper, tin, gold, palladium and titanium.

From Tech Crunch by Serkan Toto - In Japan, girls are crazy over virtual boyfriends. Webkare (Web Boyfriend in Japanese), a mix between a social network and dating simulation site, is Nippon’s newest web sensation. Geared exclusively towards girls, the site attracted over 10,000 members just 5 days after its release on September 10, racking up 3.5 million page views in the same time frame.

The site is a huge hit over here. Girls sign up and become members of a social network but also users of a dating simulation in cartoon style. They have to try to hook up with one of four male Anime characters (who are the “stars” of the site) through “conversations” and must collaborate with other Webkare members in order to move on in the game. Eventually they conquer the heart of the chosen cartoon boy.

It’s pretty weird but clever. Dating simulations have been popular in Japan for quite a while now, but Webkare marks the first time the concept has been brought online and combined with social networking functionality.

Girls choose between one of four different male cartoon characters they want to hook up with upon registration. They can then “communicate” with their digital crush in cartoon-like sequences to try to win over his heart over the course of the game. It’s also possible to meet other boys later in the story, which uses a virtual high school as the main setting.

Interaction is quite limited, as users themselves can neither type text nor “speak” to the characters. Instead, Webkare will display a short cartoon clip if you click on the boy you like (some of the clips include voice samples such as “What’s up?”, “Do you always stay in the class room until dark?” “Leave me alone!” etc.), driving the love story forward step by step.

From The New York Times by Martin Fackler - On a narrow Tokyo street, near a beef bowl restaurant and a pachinko parlor, Aya Tsukioka demonstrated new clothing designs that she hopes will ease Japan’s growing fears of crime.

Deftly, Ms. Tsukioka, a 29-year-old experimental fashion designer, lifted a flap on her skirt to reveal a large sheet of cloth printed in bright red with a soft drink logo partly visible. By holding the sheet open and stepping to the side of the road, she showed how a woman walking alone could elude pursuers — by disguising herself as a vending machine.

The wearer hides behind the sheet, printed with an actual-size photo of a vending machine. Ms. Tsukioka’s clothing is still in development, but she already has several versions, including one that unfolds from a kimono and a deluxe model with four sides for more complete camouflaging.

These elaborate defenses are coming at a time when crime rates are actually declining in Japan. But the Japanese, sensitive to the slightest signs of social fraying, say they feel growing anxiety about safety, fanned by sensationalist news media. Instead of pepper spray, though, they are devising a variety of novel solutions, some high-tech, others quirky, but all reflecting a peculiarly Japanese sensibility.

Take the “manhole bag,” a purse that can hide valuables by unfolding to look like a sewer cover. Lay it on the street with your wallet inside, and unwitting thieves are supposed to walk right by. There is also a line of knife-proof high school uniforms made with the same material as Kevlar, and a book with tips on how to dress even the nerdiest children like “pseudohoodlums” to fend off schoolyard bullies.

There are pastel-colored cellphones for children that parents can track, and a chip for backpacks that signals when children enter and leave school.

The devices’ creators admit that some of their ideas may seem far-fetched, especially to crime-hardened Americans. And even some Japanese find some of them a tad naïve, possibly reflecting the nation’s relative lack of experience with actual street crime. Despite media attention on a few sensational cases, the rate of violent crime remains just one-seventh of America’s.

Japanese Space Elevator From Times Online by Leo Lewis - From cyborg housemaids and waterpowered cars to dog translators and rocket boots, Japanese boffins have racked up plenty of near-misses in the quest to turn science fiction into reality.

Now the finest scientific minds of Japan are devoting themselves to cracking the greatest sci-fi vision of all: the space elevator. Man has so far conquered space by painfully and inefficiently blasting himself out of the atmosphere but the 21st century should bring a more leisurely ride to the final frontier.

For chemists, physicists, material scientists, astronauts and dreamers across the globe, the space elevator represents the most tantalising of concepts: cables stronger and lighter than any fibre yet woven, tethered to the ground and disappearing beyond the atmosphere to a satellite docking station in geosynchronous orbit above Earth.

Up and down the 22,000 mile-long (36,000km) cables — or flat ribbons — will run the elevator carriages, themselves requiring huge breakthroughs in engineering to which the biggest Japanese companies and universities have turned their collective attention.

In the carriages, the scientists behind the idea told The Times, could be any number of cargoes. A space elevator could carry people, huge solar-powered generators or even casks of radioactive waste. The point is that breaking free of Earth’s gravity will no longer require so much energy — perhaps 100 times less than launching the space shuttle.
