The opportunity that I‘ve known the Green Map system was the “EXPO 2005 AICHI JAPAN”. At the same time, I belonged at an environmental protection group that is organized with my university's students. The university’s campus was placed at Kanazawa-ku Yokohama. So, as Yokohama city is modernizing remarkable, I knew there is much nature surviving at there. We should keep this nature carefully, and I think we must talk about environmental preservation measures for our future. That’s why I wanted to initiate the Green Map project. It will provide us what-should-we- do-for-future, and I hope we could get A GREAT ANSWER for it!
