The Science and Technology Experience Program Invitation by JST Sakura Science Exchange Program (SSP)

This Invitation program was provided by Kochi University based on the JST Sakura Science Invitation Program and invite all following ten participants from Universitas Padjadjaran to obtain new experience and insight on Science, Technology, Cultural and Education at The Muroto UNESCO Global Geopark, Kochi University, and Kochi City.

This Program held in Kochi from 12th through 18th December 2023 and visited several special location at Muroto UGGp and Kochi City. These area are not only provided the information on the development of Science and Technology but also learning the Culture of Japan and Hazard Mitigation Management.
On the first day, the participants visited the Marine Core Research Centre (MaCRI) in Kochi University. This was the short laboratory tour that continue in 4th day. Prof. Masao Iwai explained the new method to observe map using Anaglyph Map that provide 3D visualization of Nankai Trough Map and Shikoku Island. This was the first time of the participants to experience the observation using the special 3D glasses (red and blue glasses) to observe the map from 2D to 3D visualization.

On the second day program was visiting Muroto UGGp area and went to Cape Muroto area. The participants are accompanied by the Muroto Geologist, Dr. Yoshihiro Kakizaki and Dr. Atsuko Niina. This area displayed the collision of four Tectonic plate and the continuous uplift by plate movements. The rock layer is formed in Deep Water deposit on the oceanic floor and the evidence could find the animal movement and ocean current traces, due to collide between oceanic and continental plate along south of Shikoku Island and the last tsunami recorded is in 1946. There are three main ideas developed in Cape Muroto namely Accretionary Complex, Rising Land and Active Margin. In the same day, the participant also visited Muroto High School in 221 Murotsu and presented the Geoparks in Indonesia. The student at this High School has a Geopark Study Class supervised by Ms. Ogasawara that study the uniqueness of The Muroto UGGp. The students studied some team projects with the main topic of each team was different to each other. The projects titled Fishing, Turtle-Sea, Rare Plant, and Binchotan Charcoal Team. They learned the uniqueness of each topic and conserved it. After that, the participant visited the placed that shown the intrusion outcrop (boundary layer between Gabbro and Sedimentary Rock (sandstone and mudstone)) in Sakihama Melange Area and observed the Tree of Akou (Ficus superba) at Shimura Fubo which is the one of the Biodiversity in Muroto UGGp and This tree is the one of the uniqueness subtropical plant which is embracing a big rock. Afterwards, the the participant visited the Muroto UGGp Information Centre which exhibited the geodiversity, biodiversity, and cultural diversity of The Muroto UGGp and the hazard mitigation management and monitoring as the prevention of disaster in this Geopark. The other visited place was the Tsunami shelter that used to evacuate the Muroto Residents if the Tsunami is happened. This shelter is providing emergency food, electricity, and water for evacuation process and monitoring camera to observe the outside condition.

On the third day of this program, the participants visited the lookout point of The Cape Muroto. This point is used to view the different side of The Cape Mutoro and The Marine Terrace, The West side shows the Nishiyama Plateau and the coast slope in narrower than the other side shows by the bathymetry data, and the east side shows the East Cost of Muroto. The next visited area was the Kongochoji Temple that located in 523 Motootsu, Muroto. The participantsobserved the special temple construction that resistant to earthquake. And the last geosite visited in the Muroto UGGp area is Shimura Walking Trail to observe the sandstone and mudstone pattern of the oceanic floor, the sand dyke, the fossil trance, and the ripple mark on the outcrops. Then before went back to Kochi City, the participants enjoyed the Kiragawa Street as one of the agenda. On this street, the participants observe the traditional architecture townscape that build during this period. This is one of the heritage building and beautiful townscape on the west of The Muroto City and the participants also learned the history of its economic prosperity in modern area.

The Laboratory experiences was the 4th day activities of this program at Kōchi University Monobe Campus. Prof. Masao Iwai explained the core preparation and treatment from the legacy deep sea drilling core. The process started by scanning the half of the core and the other half is saved as legacy core. This Kochi Core Center (KCC) is one of the three IODP repositories in the world and the core came from during several core survey that gathered from The Indian Ocean, Western Pacific Ocean, and Bearing Sea. Total numbers of the core repositories are approximately155 km and used for scientific and educational purpose and museum for all over the world. Besides that, the other measurement method and analysis is also available in this Institute (MaCRI) namely Rock Scanning, Palaeomagnetism Test, Sedimentary Core Dating, XRD, XRF, Fault Mechanism Test, Isotope Geochemistry Test, etc. This was our first experience that visiting Core Lab Repositories that store core sample in the freezer with temperature around -23odegree Celsius to keep the original submarine condition of the core. And then, all the participants joined the seminar with keynote speakers are Dr. Tsuyoshi Ishikawa and Ms. Tsubasa Ogasawara. Dr. Ishikawa presentation titled “Understanding Subduction Zone Earthquake” and explained the scientific drilling in The Nankai trough and the result of the study wasto explain the subduction zone that influenced the earthquake. This research also using the several new technologies such as LWD drilling technique that provide by Schlumberger during survey. Then continue by Ms. Ogasawara presentation titled “Live in Active Margin”. This seminar gave us information of the High School student’s activities of the hazard prevention in Muroto High School. the students did some analysis of liquefaction and made decision of saving mitigation and shelter area when disaster happened in Muroto. On the other hand, counselling and providing information of the disasters were also carried out in the Muroto area so that residents will have a better preparation to face future disasters. The next geo-site visited in Kochi city in this day is Ryugado Cave. This Cave is placed where various sculpture shape is naturally formed throughout the endless time and three most extensive limestone cave complexes in Japan. There are 6 interest zone in this cave namely Time Gate Prologue, Stepping Back in Time, Recall the Past, Complete change of Time, A Stage Called Time, and Time Exit. In this cave, the participant also can sight the waterfall that produce by chemical reaction between water and limestone. The other interest spot in this cave is The God Pot (one of the archaeological remain) as an earthenware vessel encased in stalactite.

On the morning of 5th day program, the participants visited the tsunami escape tower at 6307 Kure, Nakatosa, Takaoka District, Kochi 789-1301, Japan accompanied by Prof. Masao Iwai and his student name Kosaku. There are 2 escape towers to facilitate the residents if the Tsunami strikes the district area. This tower has 3 floors, and each floor has an area of around 189 m2. On each floor there are places to store food and water for reserve inventory and can be converted into a toilet when all the supplies have been used. The 3rd floor will be used if the capacity of the building is already full, and the route door must be broken to access the last floor. In this city, the population is around 3000 people and if the tsunami happed, not all the people evacuated in this tower, the people near the hill will be evacuated to nearest hill and the people near this tower will be evacuated here. This tower also provides a special route for disabled people to help evacuation easier. After the tower excursion, then visited Taisho market to introducing the traditional Japanese fish market and tasted several Japan traditional food. After market, participant went to Sakawa Geological Museum with address 360 Ko, Sakawa, Takaoka District, Kochi 789-1201, Japan. The first exhibition showed was The Museum theater that showed a video of The Geology of Sakawa, the story of Loved by Professor Dr. Makino, and Sakawa Taro’s Fossil Quiz were screened three times a day. The Participants then Continued to visit Research History Corner Room that displayed the research of Heinrich Edmund Naumann, who came to Japan in 1875 and laid the foundations for geology in Japan, as well as Teiichi Kobayashi, who in 1952 wrote a major paper entitled, “The Sakawa Orogenic Cycle and Its Bearing on the Genesis of the Japanese Islands,” which shed light on the tectonic history of the Japanese archipelago with a focus on Shikoku Island. The other room is The Main Gallery, Geo-fantastic Room which displayed the rocks, mineral gallery and also the map of hazard in Kochi. Then the last room is The Outdoor Exhibition Space which let the participant join the experience gathering fossils of Monotis, a late Triassic bivalve brought from strata approximately 200 million years ago. And the last visited area was The Asakura Main Campus of Kochi University to observe the collection of Biology and Geological Gallery in Science Building of Kochi University.

The 6th day activities were visiting The Kochi Castle and Sunday Market along Otesuji Street in Downtown in AM Time and then continued to Chikurinji Temple and Makino Botanical Garden at PM Local Time.
