The 2011 Great East Japan Earthquake and Tsunami (GEJET), reminded us Japanese of the harsh realities of the natural envi-ronment in the Japanese Archipelago and the importance of crisis management systems. However, the treatment of disasters has not been neglected in Japan, where natural disasters have historically occurred. In Japan, here are two separate approaches to handling natural disasters in formal education. The first is learning within specific subject areas, particularly social studies and science. The second is educational activities that take place outside subject teaching hours. Although natural disasters are common in the Japanese Archipelago, this arc-shaped string of islands, surrounded by the ocean and possessing a rich natural landscape, has greatly influenced Japanese culture, science and technology, and education. The Pacific Ocean coastline of the Tohoku region has been frequently hit in recent years by large killer waves (Tsunami) that have repeatedly resulted in serious damage. The main difference between the 2011 GEJET, and the previous tsunamis that hit the region is the accident that oc-curred at the Fukushima I Nuclear Power Plant. Because the perspective of understanding science and technology from a social context is closely related to issues in education today.

Abstract Background The three-spined stickleback (Gasterosteus aculeatus) is a remarkable system to study the genetic mechanisms underlying parallel evolution during the transition from marine to freshwater habitats. Although the majority of previous studies on the parallel evolution of sticklebacks have mainly focused on postglacial freshwater populations in the Pacific Northwest of North America and northern Europe, we recently use Japanese stickleback populations for investigating shared and unique features of adaptation and speciation between geographically distant populations. However, we currently lack a comprehensive phylogeny of the Japanese three-spined sticklebacks, despite the fact that a good phylogeny is essential for any evolutionary and ecological studies. Here, we conducted a phylogenomic analysis of the three-spined stickleback in the Japanese Archipelago. Results We found that freshwater colonization occurred in multiple waves, each of which may reflect different interglacial isolations. Some of the oldest freshwater populations from the central regions of the mainland of Japan (hariyo populations) were estimated to colonize freshwater approximately 170,000 years ago. The next wave of colonization likely occurred approximately 100,000 years ago. The inferred origins of several human-introduced populations showed that introduction occurred mainly from nearby habitats. We also found a new habitat of the three-spined stickleback sympatric with the Japan Sea stickleback (Gasterosteus nipponicus). Conclusions These Japanese stickleback systems differ from those in the Pacific Northwest of North America and northern Europe in terms of divergence time and history. Stickleback populations in the Japanese Archipelago offer valuable opportunities to study diverse evolutionary processes in historical and contemporary timescales.

The basic policy of the Journal of Disaster Research (JDR), as a multidisciplinary academicjournal, is to cover all types of disasters ? except for war ? through a broad comprehensive perspective. Since its inaugural issue in August 2006, the JDR has been published bimonthly,with six issues a year. 2015 marks the tenth year since the JDRfs first issue. Among the many events happening during this decade is the March 2011 Great East Japan Earthquake Disaster which was induced by the 2011 off the Pacific coast of Tohoku Earthquake.This event had two major features ? that the tsunami accompanying the earthquake caused the main damage and that it triggered a nuclear hazard accident at a nuclear power plant. The 2011 Great East Japan Earthquake Disaster was a unprecedented earthquake disaster called catastrophic hazard following two others ? the 1923 Great Kanto Earthquake Disasterthat leveled Tokyo and the 1995 Hanshin Awaji Earthquake Disaster that destroyed parts of Osaka and Kobe. In view of this catastrophic hazardfs scale, the JDR decided to publish special annual issues on the Great East Japan Earthquake Disaster for five years since 2012 in addition to its regularissues. No publication fee was charged to contributors and support was asked from corporations. Papers on the special issues are published mainly online as an e-journal though printed editions are published for archival purposes. The current issue is the fourth of these special issues, and contributors have covered the 2011 disaster from many a wide range of perspectives. 21 papers were submitted and 8 papers are accepted for publication after peer review. The editors are confident that, like the previous three issues, this issue fully measure up to the quality that was expected for the special issue. I wish to express my gratitude to the contributors and reviewers and to thank corporations for their invaluable support.

Journal of Disaster Research (JDR) published its first issue in August, 2006. Since then, we have published six issues a year on a bimonthly basis. JDR is an academic journal aimed at bringing a broad, comprehensive discussion to the subject of disasters, and thus contributing to the field of disaster prevention and reduction. Its comprehensive coverage harbors the risk of becoming unfocussed or fostering unsubstantiated conclusions. At JDR, we have dealt with this risk by making most issues special feature issues, and inviting specialists in the relevant fields as guest editors. The Great East Japan Earthquake occurred on March, 2011, five years after our first issue was published. It was a Mw9.0 earthquake that occurred off the Pacific coast of the Tohoku region. The earthquake triggered a tsunami which produced huge casualties, amounting to over 18,000 dead or missing persons. The disaster was accompanied by a nuclear plant accident, an unprecedented event in mankind’s history. The catastrophic accident at the Fukushima Daiichi Nuclear Power Plant, operated by Tokyo Electric Company, resulted in core meltdown and the release of radioactive material. At JDR, we considered it our responsibility to publish, apart from our regular issues, special issues on the Great East Japan Earthquake consisting of five yearly issues beginning with the first issue in 2012. This issue, Part 5, is the final issue. We would like to thank all of the authors who submitted articles for the five special issues, the reviewers, and many others who contributed. The special issues project on the Great East Japan Earthquake will be passed down to a special issue on the 2016 Kumamoto earthquakes occurred on April, 2016 in Kumamoto, Japan.

Five currently known Japanese species of the eutheiine genus Paraneseuthia occur on Honshū, Shikoku, Kyūshū, and Ishigaki-jima of the Ryūkyū Archipelago. The southernmost Japanese species was separated from its geographically (and very likely phylogenetically) closest relatives that live on Kyūshū by over a thousand kilometers of the Pacific Ocean. Paraneseuthia zanetae sp. n., found on Okinawa-jima, the largest Ryukyuan island, is described, filling this wide distributional gap. The new species is yet another member of the informal P. paradoxa group, which comprises all Japanese members of this genus that share similar male protibial modifications and a complicated structure of the aedeagus; also two Russian Far Eastern species show close morphological affinities to those inhabiting the Japanese Archipelago.

Abstract. The spatial distribution of oxygen and hydrogen isotopic composition (δ18O and δ2H) of stream waters across Japan was clarified with a data set compiling sample data obtained from 1278 forest catchments during the summer of 2003. Both δ18O and δ2H values showed positive correlations with the mean annual air temperature and annual evapotranspiration, and negative correlations with latitude and elevation. Deuterium excess (d excess) values in stream waters were higher on the Sea of Japan side, and lower on the Pacific Ocean side, of the Japanese archipelago. The d excess in precipitation was generally higher in winter and lower in summer in Japan. The Sea of Japan side experiences a great deal of snowfall, and seasonal changes in monthly precipitation are rather small. In contrast, the Pacific Ocean side experiences a large amount of rainfall during summer with low levels of precipitation during the winter. Therefore, the lower d excess in stream waters on the Pacific Ocean side reflects summer precipitation, and the higher values on the Sea of Japan side are affected by delayed recharge from snowmelt. The isoscapes of stream water connote not only spatially integrated but also temporally integrated isotope signals of precipitation, and provide a framework for addressing applied hydrological, ecological, or meteorological research questions at regional scales, such as the effects of climate change.

Complete Interpretation

Interpretations suggested in this article are based on the fourteenth and the fifteenth God-zilla films, Godzilla vs. Mechagodzilla (1974) and Terror of Mechagodzilla (1975), featuring the eponymous icon of the kaijū-eiga (monster films) genre and global pop culture.An analysis of diverse contexts (visual, narrative, structural, and genre) of the cinematic fight of Godzilla (the epitome of Nature) with Mechagodzilla (the epitome of Technology) makes it pos-sible to reveal details of the expression of the desire to acquire and maintain control over technology and, through that, over nature. In the context of the genre of both the analysed films, frightening elements characteristic of a horror film are overcome by mechanisms derived from science fiction, i.e. science and technology, with the concern of civilisation about threats or fatal consequences of the use of devices which get out of control.In the cinematic discourse of images of the conflict of fear of nature with anxieties of civilisa-tion, a technological demon emerges, Mechagodzilla, in an ultra-modern body made from titanium, accumulating the horror of atavistic monsters attacking humans with the new terror of powerful alien machines. The techno-terror of Mechagodzilla is contrasted with original nature, unspoilt by technological interference, which transforms Godzilla, the frightening monster and an archetype of the chaotic and destructive force of natural disasters, into a sympathetic defender of humanity.The sensitivity and cultural tradition of a Western viewer of the films, which serves as the point of departure for the analyses, initially made it difficult to derive a complete interpretation of the message; when the interpretive apparatus was broadened, however, by rooting kaiju eiga in Japanese culture, this helped overcome the problems of interpretation and enriched the reading of Godzilla symbolics with a spiritual element referring to nature.
