Dramatically accelerating seafloor mapping
through research and development by
hyper-interdisciplinary teams

Of the seafloor has been mapped


Making mapping of uncharted waters a reality.

In the seafloor lies expansive regions that have been unexplored, and with only around 100m resolution, humanity has only touched around less than 19% of the total area

With the creation of a detailed seabed map, we may be able to see findings that may be useful for many applications, such as tsunami occurrence, movement of marine resources, weather prediction, seafloor earthquakes, underwater resources such as minerals and organic matter, or for the construction of underwater pipelines and cables.

The Development of Seafloor Exploration Technology (DeSET) Project started in 2017 to support the development of new technologies that dramatically accelerate the creation of seafloor topographic maps. Venture companies, researchers, local factories, and other hyper-interdisciplinary teams from all over Japan have been formed to make technologies that are attracting worldwide attention.

In July 2020, all existing teams were reorganized as DeSET2020, and the challenge of embodying its contribution to the world in the form of technological innovation has begun.


  • 2021/03/23 DeSET holds its mid-term reporting session for 2021

    On Friday, March 12, 2021, we held the mid-term reporting presentation session of the seabed exploration technology development project “DeSET”. On the day, three teams participating in the project presented the progress of their technological development. The presentation was also streamed online to the public in order to discuss the possibility of collaboration with private companies regarding the technology developed through DeSET. On the day of the event, 170 people who were interested in seafloor exploration technology registered to attend the event. Outline of Implementation Date and time: March 12, 2021 (Friday) 10:00 AM – 12:00 AM JST Venue: Leave a Nest Co., Ltd. Head Office (4F Iidabashi Miyuki Building, 1-4 Shimomiyabicho, Shinjuku-ku, Tokyo 162-0822) Participants: DeSET 2020 team members, The Nippon Foundation, JASTO, and Leave a Nest Online streaming: to companies, researchers, and the general public who wish to attend Program summary Time Activity 10:00~10:20 Opening remarks from JASTO,…

  • 2020/12/08 The results of the seafloor exploration technology development project DeSET have been published-Possibilities of creating seafloor topographic maps using benthic organisms, electric rays-

    Leave a Nest Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo, Representative: Jyo Inoue, hereinafter “Leave a Nest”) has been a joint venture with the Japan Foundation and the Japan Advanced Science and Technology Education and Human Resources Research and Development Organization (JASTO) since 2017. We operate the “Undersea Exploration Technology Development Project (DeSET)” with the aim of establishing innovative undersea exploration technology through the fusion of different fields of academia, venture companies, town factories, and large companies. This time, as part of the results of research and development of the theme “Realization of seafloor exploration by remote sensing using sound, light, and living things” in the first phase of DeSET (2017-2019) , RIKEN Center for Biosystems Biosciences. the joint research group around the Yo Tanaka team leader device research team, bottom棲生product [1] Torpedo is [2] using the autonomous movement, demonstrated that it is possible to create a bathymetric Figure it was done.…
