坐落於日本東京市的 City Farm 天台農場有別於在歐洲和美國的天台農場。
同樣本著為地區提供糧食，City Farm 更會舉辦不同活動讓城市人了解食物的生長過程。食物的類型針對日本的飲食文化而種，例如是大米、茄子和大豆。這需要不同的養殖技術，例如大米需要在潮濕的環境下生長，天台所需要的排水和灌溉設備與西方國家的天台農場截然不同。
City Farm in Tokyo sets itself apart from European and American rooftop farms.
The idea of producing local food for the community is the same and also in Tokyo activities are organized to let the urban population witness how food grows. The type of food though is slightly different and focused on the Japanese kitchen. Crops produced by City Farm includes rice, egg plants and soy beans. This requires different farming techniques. As rice grows in wet circumstances, draining and irrigating the roof will be different from Western-world rooftop farms.
On September 1st, Iimura Kazuki opened Omotesando Farm, a rooftop garden rental space in a central upscale commercial and residential district. The farm offers sixteen small plots at rents ranging from $170 to $250 per month.
