Executive summary This report discloses the results of a Marine Stewardship Council pre-assessment of one Unit of Assessment (UoA): Pacific cupped oyster ( Crassostrea gigas Thunberg, 1793) enhanced fishery in Hiroshima Bay and Hiro Bay, Hiroshima Prefecture, Japan in the geographic region of the Hiroshima Prefectural waters, Seto Inland Sea in the Japanese EEZ. The pre-assessment was undertaken by an SCS Global Services expert team via the fishery client group led by Kurahashijima Kaisan Co., Ltd., operating out of Hiroshima Japan. To our knowledge, this is the first time that the any component of the above mentioned fisheries has undergone pre-assessment against the MSC standard. The oyster culture operation occurs in three stages, and this would be reflected in three UoAs. For the purposes of the pre-assessment, there is a single set of scores, and where outcomes may differ between the three units, or stages of production, the scores are provided based on the lowest scoring unit (or production stage with highest impact concern). Differences in scoring outcomes between these units is only considered likely when considering localized habitat and endangered, threatened and protected (ETP) species impacts (PIs 2.3.X and 2.4.X).

    PROJECT TITLE To ensure a successful spat collection, farmers and researchers need to recognize the environmental conditions for PROJECT The IoT Platform for Smart Oyster Farming 03 spawning and be ready for spawning when it occurs, all while predicting tidal currents and where they will carry the larvae. Another factor to take into consideration is the food source, plankton, and the duration of time that the larvae will need to rely COMPANY NAME The University of Tokyo on it. Until now this method has mainly been conducted by instinct, generations of knowhow passed down to each new successor. However, this project is introducing new technology, such as drone cameras, to aid in film capture and the prediction of fertilization areas. In addition to this, ICT buoys and a solar sensor nord will be released to survey and collect Smart Fisheries with the Latest Technology data about water bb temperature and salinity. These changes will make for a much more efficient process. The project will use LPWA (low power, wide area) wireless technology and then use AI and machine learning to analyze data and set up farming based on the new information. Further applications will be utilized to help with real time information sharing to aid in Link Etajima Together the process of cultivating new oysters. A Failed First Attempt Bears New Fruit Hiroshima has the highest oyster production in Japan. In oyster farming, collecting oyster larvae is essential. However, the rate of larvae collection has been decreasing, destabilizing the industry. To solve this situation, which is severe The conception of this product was initially a total coincidence.

  • Tourism As a Key for Regional Revitalization?: a Quantitative Evaluation of Tourism Zone Development in Japan
    sustainability Article Tourism as a Key for Regional Revitalization?: A Quantitative Evaluation of Tourism Zone Development in Japan Hyunjung Kim 1 and Eun Jung Kim 2,* 1 Institute of Construction and Environmental Engineering, Seoul National University, Seoul 08826, Korea; [email protected] 2 Department of Urban Planning, Keimyung University, Daegu 42601, Korea * Correspondence: [email protected]; Tel.: +82-53-580-5247 Abstract: Since the dawn of the 21st century, Japan has switched its national industry strategy from traditional industries—manufacturing and trading—toward tourism. Regional revitalization is a particularly important issue in Japan, and by uniting regions as an integrated tourism zone, the government expects an increase in visits to tourism zones. This study quantitatively evaluates whether the regions that contain a tourism zone experience a significant increase in visitors by using a quasi-experimental pretest–posttest control group design. Additionally, it examines the effects of subsidies through regression modeling. The results indicated that the tourism zones that were comprised of a narrow region in the same prefectures experienced a significant increase in visitors. The subsidy on information transmission, measures for the secondary traffic, and space formation had a significant positive impact on the increase in visitors to these tourism zones. Implications on tourism policies, urban and regional development, and community development can be obtained through this study. Keywords: tourism zone development; regional revitalization; tourism nation; Japanese tourism Citation: Kim, H.; Kim, E.J.

Außerdem ist Setouchi für alle Gourmets und Feinschmecker der Himmel auf Erden! Burgen mit blutiger Vergangenheit und Influencer Hot Spots: Drei UNESCO Weltkulturerbestätten sind hier beheimatet, die Burg Himeji, der Atomic Bomb Dome in Hiroshima und der Itsukushima Schrein in Miyajima. Der Korakuen Garten in Setouchi zählt zu den drei schönsten Gärten Japans – ein Muss für alle GartenfreundInnen. Diese Sehenswürdigkeiten sind nicht nur Sinnbilder Japans sondern zeugen von seiner feudalen Geschichte, den vielen Kulturströmungen und religiösen Einflüssen sowie seiner tragischen Kriegsvergangenheit. Miyajima gilt als eine der drei absoluten Highlight-Sehenswürdigkeiten in Japan und hat sich so zu einem Traumziel für Instragramer und Influencer entwickelt. Die Burg Himeji ist eine von 13 ursprünglichen Burgen und rühmt sich einer bewegten Vergangenheit. So war die Burg einst Schauplatz der blutigen Legende von Bancho Sarayashiki, eine der großen Geistergeschichten Japans und die Inspiration des weltbekannten Horrorfilms „The Ring“. Zutiefst erschütternd ist die Geschichte des Atomic Bomb Dome. Er ist das einzige Gebäude, dessen Außenfassade dank seiner Stahlkonstruktion der Atombombe von Hiroshima 1945 standhielt und dient heute als Mahnmal für den Frieden. Um das wahre Japan zu erkunden, in seine Geschichte und Kultur einzutauchen, bietet Setouchi viele Gelegenheiten. So kann man am Fuße der Ruinen der Takeda Burg übernachten, die auch als Japan’s Machu Picchu oder als „Schloss über den Wolken“ bekannt ist.

  • Assessment of Ichthyofauna at Oyster Rafts in Hiroshima Bay, Japan, Using Underwater Video Cameras
    Aquacult. Sci. 66(4),267-274(2018) Assessment of ichthyofauna at oyster rafts in Hiroshima Bay, Japan, using underwater video cameras * Atsushi TSUYUKI and Tetsuya UMINO Abstract: There is little information on fish communities around oyster farms, though oyster rafts provide habitats for fish and are important fishing grounds. We investigated the ichthyofauna at oyster rafts supporting Crassostrea gigas in Hiroshima Bay, using underwater video cameras. The fish species composition around the rafts was unique, consisting of identified 18 species, with low similarities to the fish community in nearby littoral areas. Several commercially important fishes, including black sea bream Acanthopagrus schlegelii, filefish Thamnaconus modestus, and surfperch Ditrema temmincki, aggregated at the oyster rafts throughout the year. The abundance of A. schlegelii (68%-85% relative abundance) accounting for most of the fish at the rafts, except in summer. The video recordings revealed that A. schlegelii, T. modestus, and D. temmincki preyed on the sessile organisms (probably mollusks, crustaceans and macroalgae) which had abundantly attached to the oyster wires. Thus, the large and persistent aggregations of fishes suggests that the oyster rafts efficiently function as an artificial reef in the regional ecosystem.
