Somewhere near Shinagawa in Tokyo I found a place near the bay filled with mini-fields. The neighborhood can use those “fields”. Families in the neighborhood with a member who is younger than 21 or older than 60 have the right to use one of those two square meter areas. The size is minimum, but I think is an excellent idea to give happiness and keep people in contact with nature in this huge city.
Look at the water deposit in the first picture, the water is also free.
