It referred to the reconstruction process, but can equally be applied to the endeavor of writing a dissertation. It was complicated to find an appropriate research topic. It was complicated to collect and understand the required data (mainly written in a foreign language) and to comprehend the complex processes that took and take place in Tohoku Region to recover from the Great East Japan Earthquake and Tsunami.

  • Approach for International Exchange of River Restoration Technology
    Approach for International Exchange of River Restoration Technology Ito, Kazumasa Head of planning office, Research Center for Sustainable Communities, CTI Engineering Co., Ltd, Tokyo, Japan Senior Councilor, Technical Coordination and Cooperation Division, Foundation for River Improvement and Restoration Tokyo, Japan Lecturer Musashi Institute of Technology Dept. of Civil Engineering Faculty of Engineering, Tokyo, Japan Abstract : About 50% of the population and 75% of the properties concentrate on the flood plain in Japan. The rivers have intimate relationship with our lives. Those conditions have been seen after modern river improvement projects that began about a century ago. The technology which was introduced from foreign countries was improved in conformity with geographical features and the climate condition of our nation, and has redeveloped as a Japanese original technology. In 1940's, Japan had serious natural disasters that were caused by large- scale typhoons. Those typhoons wiped out everything completely. Even though the government realized the importance of flood control and management after those natural disasters, civil work still aimed to economic development. Those construction works have become the one of factors for concentrating population and degrading natural environment in urban areas. Deterioration of river environment has become serious issue in urban development and main cause of pollution. The approaches for environmental restorations which were started about 30 years ago aimed to harmonize with nature environment and cities and human lives. There have been going on many projects called “river environmental improvement projects”, the “nature friendly river works” and “natural restoration projects.” The society has tried to find a way to live in harmony with nature.

    www.EUbusinessinJapan.eu Latest update: August 2013 KANAGAWA PREFECTURE Prefecture’s flag Main City: Yokohama Population: 9,079,000 people, ranking 2/47 (2013) [1] Area: 2,415.84 km² [2] Geographical / Landscape description: Kanagawa Prefecture is located in the southern Kanto region of Japan and is part of the Greater Tokyo Area. Topographically, the prefecture consists of three distinct areas. The mountainous western region features the Tanzawa Mountain Range and Hakone Volcano. The hilly eastern region is characterized by the Tama Hills and Miura Peninsula. The central region, which surrounds the Tama Hills and Miura Peninsula, consists of flat stream terraces and low lands around major rivers including the Sagami River, Sakai River, Tsurumi River, and Tama River. [2] Climate: The climate is moderate due to the warm current running along the Pacific side of the archipelago. [2] Time zone: GMT +7 in summer (+8 in winter) International dialling code: 0081 Recent history, culture Kanagawa has played a major role in some significant periods in Japan's history. The first began in 1192, when the first military government was established in Kamakura. This made Kanagawa the centre of the Japanese political scene. The second period commenced in 1859, when the Port of Yokohama was opened to the world after more than 200 years of strict national isolation. Since then, Kanagawa became the gateway for the introduction of Western civilization. The third period was the 1950s, when the Japanese economy was being reconstructed after World War II. During this period, along with the development of the Keihin Industrial Belt, Kanagawa played a significant role in rebuilding the war-devastated Japanese economy.

  • Restoration of Tsurumi River
    Restoration of Tsurumi River Tsurumi River basin was quite activated from the late 1960s with rapid city development, but it also came to have various problems such as flood control, environment, and disaster prevention. Given the situation that flood control safety level was hard to maintain, a committee of academic experts, basin local government, and river administrator was set to find a basin-wide solution for integration of river development and flood control measures. This is a pioneer of total flood control efforts in Japan. Beyond the basin measures such as rain runoff control, the local government’s urbanization plan and development projects were involved. Key to Restoration ¾ Tsurumi River basin water master plan (flood water management, normal water management, natural environment management, earthquake and fire management, and waterfront partnership management) ¾ Water quality improvement Overview of the River Tsurumi River, a class A river originating in Machida City in Tokyo, flows through Aoba Ward, Midori Ward, Tsuzuki Ward, Kouhoku Ward, and Tsurumi Ward (Yokohama City), and Saiwai Ward (Kawasaki City). It flows into Tokyo Bay from Tsurumi Ward. Its total length is 42.5 km and the basin dimension is 235 km2. Though activated from 1960s with rapid city development, it had various problems such as flood control, environment, and disaster prevention. Basin local government and people work together in establishing “Tsurumi River Tsurumi basin water master plan,” which serves as the total guideline for water cycle River revival including rain runoff control. Project Efforts for Restoration Tsurumi River basin water master plan includes: 【Flood water management】 Water control measures are taken basin-wide to secure Tsurumi River basin against flood and to minimize flooded buildings and houses due to abnormal downpour.

  • Flood Control in Small Urban Rivers: an Example of River Projects in Tokyo
    Urban Water 215 Flood control in small urban rivers: an example of river projects in Tokyo K. Sato1, K. Masuhara1, S. Mochida1, T. Yamamoto2, H. Gotoh3 & M. Takezawa3 1Tokyo Metropolitan Government, Japan 2Chuo College of Technology, Japan 3Department of Civil Engineering, Nihon University, Japan Abstract The Tokyo Metropolitan Government (TMG) has conducted a variety of river projects to protect citizens and their property from damage due to flooding, storm surges, and landslides. Projects have also been undertaken to improve and create riversides that support nature, and to protect and restore the natural environment. The hardening of urban and inner city areas with high population densities and developed areas have relatively poor water retention and flood prevention properties. Consequently, these areas have sustained extensive water damage during times of heavy rainfall and flooding. Indeed, extensive flood damage was observed in downtown areas as recently as September 2005 and August 2008, demonstrating the need to implement additional flood mitigation measures to prevent flood damage in the metropolitan area. The number of rivers currently under the direct management of the TMG is 61 class A rivers and two class B rivers, which together measure 494.82 km. In addition, the city office of the TMG also controls 33 class A rivers and 13 class B rivers, which together equal 215.91 km. The main projects undertaken by the TMG is small river development, reinforce of lowland, improvement of the river environment for ecology, improvement of sediment disaster control facilities, development of software programs, river enlightenment activities and improved shoreline protection measures. In 2010, the total costs of river projects amounted to approximately JPY 65 billion.
