Den'enchofu is famous as a planning example of suburban residential developments by Den'en-toshi Co. It has the radial-circular road system, but its original idea plan was changed for many reasons. First, the road system failed to make an axis clear because of the unsuccessful land purchases. Second, Tokyo City planned a new road (Kanpachi-dori), and it seems to have caused the division of the area. Moreover, the difference in administrative areas has had much more effect on the residents. Third, the land use agreements in the original contact between the company and the purchasers were violated by the succeeding company. Den'enchofu-kai, a self-governing residential organization made much effort to save the environment. On the whole, the idea of Den'en-toshi Co. has been half realized.
