Housing Problems
One of Tokyo's main problems is housing even though there are more than enough houses for everyone. People want to live close to the city centre since that is where most jobs are but because of this the city centre has huge congestion problems. Tokyo is constantly expanding and the only way inside the city from the outskirts of town is to use your car or catch public transport. That leads on to another one of Tokyo's problems, the traffic problems. Trains and buses are often filled to the brim with people and the streets are almost at a constant standstill. Most streets in Tokyo are tiny and are barely one way so getting to the city centre is almost impossible unless you wake up at 3:00 in the morning.
Pollution
One of the biggest issues for the local authorities in the metropolis is waste, both industrial waste and household waste, and in particular non-combustible waste, not because the technology is not available to process such waste, but rather because of problems in the geographical location of processing facilities. The local administration has to cope with its citizens' Not In My Back Yard attitudes. The average weight of daily waste per person has almost doubled in the past two decades, and in the metropolitan areas is twice as great as that in the outskirts of Tokyo. In Tokyo, 1.1-1.3 kg of waste per person has to be collected daily. In the city of Tokyo alone, two-thirds of the total waste (2.6 million tons per year) is processed (burnt), while the other one-third is used for landfill in the Bay. In the next decade, more effective collecting and processing systems will be needed, and the administrative principle will be that the waste should be processed where it is produced, i.e. in our own backyards.
Crime
Tokyo has one of the lowest crime rates in the world and is almost safer to walk alone at night compared to day. The crime rate has been increasing over the past three years but is still relatively low.
