In recent years, heavy rainfall has frequently occurred for the first time in observation history due to climate change associated with global warming. Therefore, in the future, it is important to use rainwater as a water resource and create a town that incorporates groundwater recharge by infiltration of rainwater. To this end, the Architectural Institute of Japan has published "Guideline for Rainwater Harvesting Architecture (AIJES-W0002-2011, AIJES-W0002-2019)" and "Technical Standards for Rainwater Harvesting (AIJES-W0003-2016)". The Guideline for Rainwater Harvesting Architecture specify details on the design, installation, and operation of rainwater harvesting systems according to four basic technologies: rain collection, rain holding, rain control, and rain distribution. The Technical Standards for Rainwater Harvesting proposed a new concept called “Rain Stock” that stores and uses rain on the site. This report introduces each standards, evaluates the performance of rain stock proposed in the Technical Standards for Rainwater Harvesting, and discusses future issues and prospects.
