This paper aims to organize water sources used in 49 daimyo gardens in Edo, and to investigate the relationship with the waterworks supply range and usage situation to clarify the impact of waterworks on gardening.

It can be said that there were management systems of a self-contained pond garden doesn’t depend on waterworks.
