Of these species, T. hakonensis is widely distributed in Japan and is important in commercial and recreational fisheries. Two species, T. hakonensis and T. brandtii, exhibit anadromy. In this paper, information on the protistan and metazoan parasites of the four species of Tribolodon in Japan is compiled based on the literature published for 106 years between 1908 and 2013, and the parasites, including 44 named species and those not identified to species level, are listed by higher taxon as follows: Ciliophora (2 named species), Myxozoa (1), Trematoda (18), Monogenea (0), Cestoda (3), Nematoda (9), Acanthocephala (2), Hirudinida (1), Mollusca (1), Branchiura (0), Copepoda (6 ), and Isopoda (1). For each taxon of parasite, the following information is given: its currently recognized scientific name, previous identification used for the parasite occurring in or on Tribolodon spp.; habitat (freshwater, brackish, or marine); site(s) of infection within or on the host; known geographical distribution in Japan; and the published source of each locality record. -

Mitigation of Flood Hazards in Japan
River Basin Management IV 271 Mitigation of flood hazards in Japan M. Takezawa1, H. Gotoh1 & Y. Takeuchi2 1Nihon University, Tokyo, Japan 2Japan Infrastructure Partners Abstract In recent years, there have been instances of unusually heavy rain in Japan, including rainfall in excess of 200 mm/day. The aim of flood-control planning in Japan since 1945 has been to confine river water to within riverbanks and to ensure that levees protect river basins from flooding. In many rivers, dams were constructed in upstream areas and long levees were built along the riverbanks. The main aim of flood-control planning is to prevent the flooding of river basins by the over-flow of river water across riverbanks; however, as rainfall prediction has recently become difficult because of the effects of global warming, the main emphasis of flood-control planning has shifted from prevention to providing areas of refuge. Flood hazards must be dealt with by ‘hard measures’ such as levees and reservoirs, and ‘soft measures’ such as the provision of hydrological information, regulation of land use, and evacuation advice. In 2001, the Japanese Government made it mandatory for all regional bodies to compile and distribute flood-hazard maps to inform inhabitants of the danger of flooding and the locations of sites of refuge for all inhabitants. It is difficult to provide residents with complete protection from flooding hazards. Many people in Japan live alongside rivers, and Japanese culture has long encompassed wet-rice cultivation. Communities have always lived under the threat of flooding, but the profitability of river water makes it preferable to live close to a river even if flooding occurs at times of heavy rain. -
River and Wetland Restoration: Lessons from Japan
Articles River and Wetland Restoration: Lessons from Japan KEIGO NAKAMURA, KLEMENT TOCKNER, AND KUNIHIKO AMANO River and wetland restoration has emerged as a worldwide phenomenon and is becoming a highly profitable business. Although researchers worldwide know a lot about restoration practices in Europe and the United States, we have only scant information about the activities in Japan, where more than 23,000 river restoration projects have been conducted during the past 15 years. In Japan, restoration is a daunting business because of the high human population density, urbanization, and harsh environmental conditions. Here we provide an overview of the various restoration activities in Japan and discuss the lessons that we can draw from them.
