Abstract

The Japanese water industry is facing a transitional period reflecting changes in populations, natural disasters, the ageing water pipelines and facilities, difficulties associated with inheriting legacy technologies, and so on. The Ministry of Health, Labour and Welfare, which is the regulatory agency for the water supply businesses in Japan, is aiming to revise the Waterworks Act to strengthen the foundations of the water utility management. This chapter aims to provide an overview of the past and current Japanese water industries and to examine the course of reform of the water supply businesses in Japan.

Notes

  1. 1.

    The Statistics of Waterworks, Japan Waterworks Association.

  2. 2.

    Strictly speaking, the MHLW approves only water supply business that uses surface water as the main water source. For example, Kumamoto City, which depends 100% of water source on underground water, has a population exceeding 600,000 but has been approved by Kumamoto Prefecture.

  3. 3.

    All empirical analysis using data of the water service business in Japan adopts only LWS samples. This is because financial and operational data are available only for LWS not for SWS and PWS.

  4. 4.

    Sudden and heavy downpour events are termed in Japan as ‘Guerrilla heavy rainfall’.
