Let's talk about public transports in Tokyo. In Tokyo, public transportation is not an alternative - it's main form of commuting. Even rich people with fancy cars travel by public transportation. Unlike many other countries, in Tokyo it is fast, clean, and available. Trains and subways are very efficient, and they run on time almost to the second; delays are rare, and even 5-minute delays comes with an apology, and it's even a real reason for being late to a job. Subways in Tokyo are extremely clean, one of the best in the world. Floors, seats, and windows are kept spotless; eating and drinking often discouraged, and cleaners can often be seen working during operating hours. Since subway stops are located very dense and a lot, you are never far from them. The cost is also cheap, around $1.10 - $2.20. Moreover, it travels faster than cars, and that is why it is main option for commuting.
Green areas, parks and gardens, one of the most important places in any urban areas, and they are a lot of them in Tokyo. Most of neighborhoods have at least a small park, and this is because Japan has strong connection to nature; for Japanese people parks and gardens are not just places where people can walk or rest, it is tradition. Traditional Japanese gardens are places designed with rocks, trees, and ponds, and they meant to create peace. Another thing is that there are almost no trash bins outside. All of them were removed after a terrorist attack in the 90s. However, streets are every clean, and the reason is that the public itself keeps them clean. Japanese people don't litter; everyone takes personal responsibility for their trash, so most carry it home in a bag. Therefore, streets are very clean, and cleaners rarely can be seen outside.
