Book Description
Beaches in Japan have been eroding since the 1970s as a result of the artificial land alterations. Approximately 3000 fishing ports and 1000 commercial ports have been built nationwide, as well as 2532 large dams being constructed in the upstream basins of large rivers. Due to the port and dam developments, fluvial sand supply has significantly reduced resulting in shoreline recession around the river mouths. Continuous sand supply along the coastline has also been obstructed by the port breakwaters. The formation of wave shelter zone by the port breakwaters induce longshore sand transport, thereby leading to an accretion of large amount of sand in the wave shelter zone and erosion in the surrounding area. Thus, almost all causes of the beach erosion in Japan are due to anthropogenic factors. The exact situation of the beach erosion has never been clear in literatures that are written in Japanese, or in English. Coastal engineers can and should learn from these results, otherwise the same situation and problems, which were induced by excessive coastal development without protection measures and due attention given to nearby coasts, will recur throughout the world.Textbooks on coastal engineering, that were already published, describe only the theoretical fundamentals of the subject, but lack the practical perspectives and field studies. The book examines many coastal areas as examples, highlighting the various erosion factors which should be avoided elsewhere globally. This book was first published in Japanese in 2004, and was translated into English by the present author.

Book Description
Beaches in Japan have been eroding since the 1970s because of artificial land alterations and unsustainable coastal development. Almost all causes of the beach erosion in Japan are due to anthropogenic factors — as a result of human activity. This book presents the state of the beaches throughout Japan, looking at the current reality and the classification of causes of beach erosion using real-life, illustrated examples. It then goes on to look at practical models which can be used to predict changes to different types of beaches, and concludes with investigation of beach erosion as a wider structural problem. Lessons learnt show the manner in which excessive coastal development without clearly identified measures for beach protection can have widespread global ramifications.This second edition presents new findings from field studies carried out on Japanese beaches, along with the development and improvement of the numerical model presented previously. In addition to the first edition, six new examples of the beach erosion in Japan are included, as is new analysis of the BG model (a model for predicting based on Bagnold's concept), which can be applicable to various field problems.Originally published in Japanese (2004), this updated version gives clear practical guidance to coastal engineers working to prevent irreversible beach erosion and sustainable coastal development policy.

Book Description
Headland-bay beaches (HBBs) are ubiquitous in coastal environment. They exist around the world naturally or artificially as byproduct of engineering project. Though in various shapes, sizes and stability, a HBB in static equilibrium not only is a delight for visitors, but also offers hope for better beach protection, restoration, recreation, and shoreline management. With an empirical parabolic model now available, the stability of an existing HBB can be verified, the future bay shape downdrift of a harbor can be predefined, and a stable HBB can be designed.Although a plethora of books are available for coastal and ocean engineering and geomorphology, only a countable few have covered engineering applications of HBBs. On the contrary, this book with focus on the HBBs in static equilibrium aims to offer a comprehensive volume with knowledge and applications for coastal scientists, engineers, managers, students, and the general public interested in HBBs. Useful software tools for HBBs (MEPBAY, MeePaSoL, and SMC) are introduced in the book to aid in applications.The authors have set out to make this book the first unique publication on HBBs, by bringing together the old coastal geomorphic knowledge and new concepts for static bay beaches. This book also provides numerous examples using the static bay beach concept to assist coastal scientists and engineers on planning and pre-design of a stable HBB, and for experimentalists, consultants, and numerical modelers to alleviate the burden of comparing planning options and conducting laborious physical experiments on coastal sedimentation problems.

Book Description
This book explores contemporary tourism and coastal developments in Hyogo, Japan—the nation’s only non-peninsular prefecture bordering two oceans. In striking detail, Dr. Lesley Crowe-Delaney skillfully contextualizes tourism industry and policy; illustrates coastal urban and rural development dichotomies; discusses hegemonic devices of nationalism, nature, authenticity and tradition, as embedded in tourism strategies; and highlights the nuances of Japan’s distinctive administrative systems and specific approaches to tourism. Crowe-Delaney reveals the strains placed on coastal communities when fisheries, tourism, sustainable development, and national policies intersect, offering readers an enlightening discourse of the potency of tourism as a rejuvenation tool.

Book Description
Japan’s oceans demand our attention. Violent, prolific, and changeful, they define life and death on the archipelago: pushing the shore under the rush of tsunami, charging typhoon circulation, feeding millions, and seeding conflicts over territory and resources. And yet, Japan studies remains largely beholden to a terrestrial view of the world that is at odds with the importance of the sea. This “terrestrial bias” also means that on those occasions when oceans are recognized they are most often presented as dividers or connectors—spaces in between rather than rich ecologies and meaningful sites. Oceanic Japan is meant to help readers re-envision Japanese history in order to show how the seas created the country that we know today. The book convenes a diverse, multinational, multidisciplinary group of scholars to expand the scope of Japan studies and the field of environmental humanities. The chapters draw from the broader turn to the sea—characterized by new oceanic and terraqueous perspectives—developing within these fields and in areas such as Pacific history and Indian Ocean studies. The volume editors' vision is bifocal. On one hand, they aim to reorient East Asian studies and Japan studies to the sea, underlining how oceans have shaped dynamics from the Tokugawa Era forward into the age of empire and the crisis of the Anthropocene. On the other hand, they argue for a more nuanced environmental approach within the burgeoning field of Oceanic studies. Seeing oceanic spaces as more than entrepots or political spheres requires thinking in new, often vertical, volumetric ways. The chapters follow human and non-human actors to recognize the variegation of watery ecologies through winds, tides, coasts, seabeds, and currents such as the Kuroshio and Oyashio, which have always shaped life on the archipelago.
