概要	To investigate the effect of the COVID-19 (coronavirus) pandemic on residential water use behavior in Japan, we conducted a web-based survey of 1310 people throughout Japan in March 2021, one year after the initial spread of coronavirus. The survey was designed to provide an average picture of Japan. The survey revealed that the time respondents spent at home increased during the pandemic for both men and women in all age groups by an average of 1 h, an increase of 9%. Changes in water use behavior increased almost in proportion to the increase in time spent at home, except for the frequency of defecation, which was limited to once a day. The amount of time spent in the washroom increased by 13%, an increase of more than 1.4 times the increase in the amount of time spent at home.
