Which one has a better environment, Japan or Singapore?

Japan is already small enough, and Singapore is even smaller. In Asia, apart from Macau (18,874), the only other population density is Singapore (6,428); Japan’s population density is only 339; the highest population density in Tokyo is only 5,384, and Hokkaido is only 73. The above figures are the number of people per square kilometer. Because Singapore is too small and most of it is urban; the density of cars is also too high, so air pollution is serious. Although the Singapore government has adopted various restrictive policies on car purchases, it still cannot stop the increase. One thing that can tell you about the level of traffic congestion in Singapore is that there is something that is very popular in Singapore (car toilets). Japan handles this aspect well. Japan’s forest coverage rate is 66% (they all go to Malaysia and other places in Southeast Asia to cut down other people’s forests (to buy them)). Overall, Japan is better.

Japan does have many holidays. The Japanese Emperor’s birthday is a national holiday. If the Emperor dies and a new Emperor is replaced, then the holiday will be added by one day; then the Emperor’s birthday can no longer be called “Emperor’s Birthday” Then, following the fashion, the day was renamed "Green Day". What are you doing? Let’s plant trees! Many Japanese young people welcomed it very much and jokingly said, "It is a good thing if more emperors die."
