Proceedings of the 4Th Japan and US Workshop on Seismic Measures for Water Supply The 4th Japan/U.S. Workshop on Seismic Measures for Water Supplies The 4th Japan/U.S. Workshop on Seismic Measures for Water Supplies was held in Kobe, Japan in January 2005 to commemorate the 10 year anniversary of the Great Hanshin-Awaji Earthquake. The basic objectives of the workshops are: • to create a forum for the active discussion and exchange • identify and document best available current technologies in water system seismic mitigation practices • provide a practical information source on seismic mitigation efforts for water utilities • identify technology improvements needed to practically and efficiently advance water system seismic practices. Attendees included 14 representatives from the U.S., 41 from Japan and 3 from Taiwan. There were 24 papers presented during seven meeting sessions during the three day event. AwwaRF subscribers that attended and provided both technical papers and presentations include: Contra Costa Water District, San Francisco PUC, East Bay Municipal Utility District, Los Angeles Department of Water and Power, City of San Diego, Portland Bureau of Water and Seattle Public Utilities. The workshop was funded by Awwa Research Foundation and the Japan Water Works Association, as well several other organizations and utilities.

I am Nobuhiro Matsushita, deputy mayor of Kobe City. I would like to welcome you all to Kobe. As Kobe City observed the 10th anniversary of the Great Hanshin-Awaji Earthquake on January 17, 2005, it held a memorial ceremony in the presence of their Majesties the Emperor and Empress. Also, the United Nations World Conference on Disaster Reduction was held in Kobe from January 18 to 22. I would like to take this opportunity to express my sincere appreciation for the help and support extended from the rest of Japan as well as abroad, with which our waterworks facilities have finally been restored to its current state. It is significantly meaningful that the 4th Japan-US Workshop on Seismic Measures for Water Supply is being held in Kobe this memorable year. I would like to extend a warm welcome to you all on behalf of Kobe City. I was told that this workshop is being held under the cosponsorship of the Japan Water Works Association and the American Water Works Association and aims to foster working-level officials who promote the creation of earthquake-resistant waterworks systems by sharing information on research

It is my great pleasure to have this opportunity to talk on “Dams in Japan” at this opening ceremony of 24th ICOLD Kyoto Congress1. 24th ICOLD Congress 2 to 8 June 2012 ～ Kyoto, Japan 【JWA】 Norihisa Matsumoto Japan Commission on Large Dams 1 2. This diagram shows the increase in the number of dams which are higher than 15 m. Before 1900, we had about seven hundred irrigation dams. We started our modern dam construction in the end of the 19th century. The first masonry concrete gravity dam was completed in the year 1900. In those early days, the irrigation dams dominated in numbers, and hydropower and multipurpose dams increased later on2.

Japan's Experiences on Water Supply Development March 2017 Japan International Cooperation Agency Water Partners Jp Co., Ltd. Nihon Suido Consultants Co., Ltd. Preface Access to safe water is an essential part of human rights and the foundation for a healthy life. However, even today, the world witnesses many instances of people lacking access to this essential commodity. To counter this situation, a new global agenda - the Sustainable Development Goals (SDGs) - was unanimously adopted by the member states of the United Nations in 2015. The agenda included a dedicated goal on water (Goal 6) that aims to “ensure availability and sustainable management of water and sanitation for all.” Target 6.1 of Goal 6 estimates that “by 2030, achieve universal and equitable access to safe and affordable drinking water for all.” Japan has been contributing for years to the development of the water supply sector. When Japan started to construct modern water supply systems, it faced vast challenges with regard to expansion of service coverage and improvement of service quality, as is the case in most developing countries. However, it overcame these challenges with the help of proactive efforts, including the introduction of the overseas technology, and achieved the objective of nationwide coverage of safe water supply.

Nevertheless, not all shared river basins are associated with water conflicts. Rivers in Japan and Malaysia play a significant role in regional economic development. They also play a significant role as water sources for industrial, domestic, agricultural, aquaculture, hydroelectric power generation, and the environment. The research aim is to determine the similarities and differences between the Sagami and Muda River Basins in order to have a better understanding of the governance needed for effectively implementing the lessons drawn from the Sagami River Basin for improving the management of the Muda River Basin in Malaysia. This research adopts qualitative and quantitative approaches. Semi-structured interviews were held with the key stakeholders from both basins and show that Japan has endeavored to present policy efforts to accommodate the innovative approaches in the management of their water resources, including the establishment of a river basin council.
