Relationship between housing value and plumbing fixtures

Abstract

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. Study by So and Shimizu（2019） shows that the ability to plumbing fixtures has a certain impact on rental housing rents. It has also been observed that rents rise when older rental housing is refurbished with plumbing fixtures. However, plumbing facilities have the effect of increasing the satisfaction of residents.
