Input: Article: It's 5pm on a Friday and I'm standing in a coffee shop above Shibuya crossing - one of the most busiest place in Japan where more than a thousand of Tokyo's smartly dressed people gather at eight points, ready to cross - then rush straight for each other. It looks like they must bump into each other, but It's amazing that they all manage to reach the other side safely. But the real reason I'm here is that I want to see people crash. I want businessmen to knock into each other, their umbrellas flying off their arms, and uniformed schoolchildren hitting grannies. Why may I see this now, but wouldn't have had the chance even a year ago? It's very simple - smartphones. Smartphone use is booming in Japan. In 2012, only about a quarter of Japanese used them, most being perfectly happy with their everyday mobiles. But now more than half of all Japanese now own a smartphone and the number is rising fast. But with that rise has grown another phenomenon - the smartphone walk. Those people who're staring at a phone screen adopt this kind of pace- their head down, arms outreached, looking like zombies trying to find human prey . Surprisingly, an American named Michael Cucek who has lived here for more than 20 years told me smartphone walk probably wouldn't be a long-term problem. Japanese phone manner is in fact better than anywhere else in the world - hardly anyone speaks on their phones on trains, and teenagers wouldn't dare broadcast music out of one. If things got truly bad at Shibuya, the police would just start shouting at people to look up. But really, is the smartphone walk such an annoying problem? There's only one way to find out. So I leave the coffee shop, head down to the crossing and start typing an email, promising myself I won't look up until I get to the other side. When they start walking past me, it's my time to cross. As I step forward, the experience quickly becomes nervous - legs jump in and out of my vision without warning, while shopping bags fly towards my face before being pulled away at the last moment. I'm sure I'm going to get hit, but after a few seconds I relax. It's OK. Everyone's reacting for me. I expect to see two smartphone walkers just like me. But instead I find a young couple, very much in love and very much refusing to let each other's hands go just to give way to a fool on his smartphone. The girl gives me such a look of dislike that I quickly apologize and rush round them. That look was enough to ensure I'll never be smartphone walking again.
