Osaka is the third most livable city in the world after Vienna and Melbourne, according to the research unit of British magazine, The Economist. Osaka didn't make the top 10 before. The report attributed its rise to improvements in "quality and availability of public transportation, as well as a consistent decline in crime rates. I was surprised when I read the news on the website. But I am glad that Osaka is evaluated as a livable city in the world. I am satisfied with the public transportation system in Osaka. Arrival and departure times of the train are accurate and they are displayed on the electric board in the train stations. It is difficult for me to accurately evaluate the rank of Osaka among the others cities in the world, because I have not experienced living in other cities to properly compare them and make a ranking.
