Goal 6 of the SDGs has been achieved in Japan, ensuring access to water and a good sanitation environment. According to the 2008 Housing and Land Statistical Survey, 2.8％ of rental apartments do not have bathrooms, while only 0.7％ of owner-occupied houses do. And the quality of plumbing equipment is improving year by year. Study by Suzuki and Arai（2021） shows that the impact of plumbing fixtures on the price of second-hand detached houses is small.
