Therefore, the Ministry of the Environment (former Environment Agency) began the acid deposition survey from Japanese Fiscal Year (JFY) 1983 to comprehend the condition and influence of acid deposition in Japan with the aim of preventing harmful influence from acid deposition. Also, in order to maintain the acid deposition monitorihng in wide-area for long term, “The long term monitoring plan of acid deposition” was formulated on March 2002. Based on the plan, the Ministry of the Environment has implemented wet/dry deposition monitoring, land water monitoring for lakes, and soil/vegetation monitoring cooperating with local governments since JFY 2003. This report shows the results of long term monitoring conducted from JFY 2003 to JFY 2007, in addition, summarizes the results of the intensive survey on Ijira lake catchment area of which the soil is known to be acidified, from JFY 2005 to JFY 2007 focused. In recent years, transboundary air pollution in North-East Asia is pointed out as one of the causes of widening area that photochemical oxidant warnings are announced and increasing its concentration. For these reasons, not only acid deposition but also transboundary air pollution including ozone and aerosol is growing concern. We reviewed the existing study results such as calculation results of atmospheric simulation models as well as the condition of transboundary air pollution. This report is summarized about the result of study conducted at the acid deposition committee and its atmospheric issues sub-group and ecological impact sub-group established in the Ministry of Environment. The related data was collected and analyzed at Acid deposition and oxidant research center and it organized four working groups (acid deposition analysis, ecological impact analysis, Ijira lake intensive survey, transboundary air pollution) to analyze and review the research results. We extend a special thank to everyone concerned who cooperated with conducting and summarizing this monitoring survey.

  • Three Large Historical Landslide Dams and Outburst Disasters in the North Fossa Magna Area, Central Japan

The area upstream of the landslide dam is submerged under water and the downstream area is flooded when the landslide dam breaks. In recorded history, as many as 22 landslide dams have formed upstream of the Shinano River and the Hime River, in the northern part of Nagano Prefecture in central Japan, and all except three have subsequently broken. This abundance of landslide dams is probably caused by the geotectonic background of this area, which is located at the western end of the “Fossa Magna” major tectonic line. In this study, we examined three large historical landslide dams and outburst disasters in the north Fossa Magna area.

Key words: Diptera, flesh flies, new species, new genus, Sarcophagidae, Japan INTRODUCTION The collection of Sarcophagidae made by the first author was studied during the course of the taxonomical studies on the calypterate muscoid flies from Japan since 1970 (Kurahashi, 1970). This was a revision of the subfamily Miltogramatinae dealing with seven genera and 14 species. Before this, Takano (1950) recorded seven genera and nine species of Japanese Sarcophagidae. Many investigation on the Japanese flesh flies made by Drs. K. Hori, R. Kano and S. Shinonaga beside the present authors. The results of these authors were published in the part of Sacophagidae, Fauna Japanica (Insecta: Diptera) and treated 23 genera and 65 species of the subfamilies of Sarcophaginae and Agriinae (=Paramacronychiinae), but the subfamily Miltogrammatinae was not included (Kano et al., 1967).

    Minoji The Minoji is a road that connects Miyajuku (present day Nagoya City, Atstuta Ward) along the old Tokaido Road to Taruijuku(present day Fuwagun in Gifu Prefecture) along the Nakasendo Road (old mountain pass route). This Minoji passed through seven lodging towns of Nagoya, Kiyosu, Inaba, Hagiwara, Okoshi, Sunomata, and Ogaki. Such alternate side routes of the Tokaido and Nakasendo among five roads radiating from Edo were placed under the control of the Edo Shogunate’s road magistrate. The Minoji was greatly used to allow bypassing the sea traffic between Kuwana and Miya along the waterway route Akasaka Nakasendo Goudo Tarui Kano known as Shichiri no Watashi.

  • History of Flood Fighting in the Kisosansen River Basin
    Flood Recovery, Innovation and Response I 123 History of flood fighting in the Kisosansen River Basin Y. Takeuchi1, M. Takezawa2 & H. Gotoh2 1Japan Infrastructure Partners, Japan 2Civil Engineering of Science & Tech., Nihon University, Japan Abstract The Isewan Typhoon caused considerable damage to the downstream regions of the Kisosansen River Basin on 26th September 1959. It caused approximately 4,500 deaths in and around Nagoya City, the most industrial city in Japan. This study describes the history surrounding the major flood mitigation projects related to land use in the Kisosansen River Basin since 100 A.D. when paddy fields were first established on the alluvial plain. Land use of the area gradually evolved to cover the entire alluvial plain, developing from subsistence farming to modern sophisticated industry. This study shows that economic development in the both side plains of the river has been altered since the construction of the eastern side dike on the Kiso River. The Kisosansen River Basin, with a catchment area of 9,100 km2, is drained by the Kiso River, the Nagara River and the Ibi River. These rivers previously flew in the Nobi Plain as a single river, with successive floods producing a change in the main channel. Keywords: Isewan Typhoon, Kisosansen River, history of flood mitigation works, benefits associated with flood mitigation works. 1 Introduction While flood damage has always been associated with agriculture and human settlement, they have increased in size and frequency as land use has changed for settlement, agriculture, commerce and industry. The Isewan Typhoon affected the downstream regions of the Kisosansen River Basin on September 26, 1959.

  • Midstream of Kiso River Affected by Tensho Mega-Earthquake
    6th International Conference on Earthquake Geotechnical Engineering 1-4 November 2015 Christchurch, New Zealand Midstream of Kiso river affected by Tensho mega-earthquake Katsuhiro Nishimura1, Masao Okuda2,Yukihiko Kani3,Yoji Nakane4and Kiyoshi Hayakawa5 ABSTRACT A flood struck the midstream area of Kiso River on August 9, Tensho 14 (1586). This flood has been called “Tensho river flood”. The midstream alignment of Kiso River has been altered at a range of 20km length during Tensho river flood. This paper presents the results of study on the activities of faults and the influence of ground changes derived from the Tensho mega-earthquake. Also, this paper presents the possibility that those watercourse changes of old Kiso River during Tensho period was due to the Tensho mega- earthquake rather than the Tensho river flood. Introduction Kiso River, Nagara River and Ibi River, which is called “Kiso three-rivers”, are flowing through the Nobi Plain including Nagoya city as shown in Fig.1. The Kiso three rivers repeated the large- scale watercourse change, the alluvial action, etc. and then, the said three rivers had formed a vast Nobi alluvial plain. When the alluvial lowlands in the Nobi Plain had been cultivated by people during the historic times, the flood damage occurred often at the area of midstream and down-stream of the Kiso three rivers. Those flood damages became to be recorded. It is known that a historical flood which is called the Tensho river flood at Kiso River Had changed a part of Kiso River’s watercourse. The Tensho river flood occurred in 1586, but it was not so large in scale to regard as the fundamental cause of the water-course change at Kiso River(Iida,1984).
