I have to admit; I was not an ECO friendly person in the past, but Japan has changed all that. I was used to having two big trash bins outside the house provided by the city and all we need to do was to put all trash in the black bin and all greens in the green bin. Then, we take the bins out once a week to have it empty. Simply as that. Japan is quite different. Every household are required to recycle their trash and throw them out on certain days. Anything is not consider regular trash. We have to separate paper, plastic, PET bottle, metal, aluminum, and glass bottle individually. Let me explain.
