Activity area status and issues

Aiming to reorganize the relationship between “Sea”, “Port” and “City” through social, civil and academic collaboration and citizen’s participation, in the Yokohama seaside and seaside-city area, a town embraced by the sea (embracing the sea) as “Yoko” and “hama” mean “side” and “beach”, respectively, we want to consider and propose the 21st Century “Yokohama Marine Environment Future City”.

Establishment history

For the coastal areas (ports and harbors) that may be less profitable in the future, examination of future concepts such as the so-called “inner harbor concept” (Marine-City Yokohama concept 2059, Tokyo Metropolitan Coastal Area Reorganization Development Master Plan, etc.), which has been studied and proposed since around 2008, and examination of the environment and energy (Yokohama City Environmental Future City Planning, Blue Carbon Project, etc.) have been done as well as citizen’s participation in Yokohama Marine Citizen College (since 2014). In the meantime, considering the role of an international marine environment city in the 21st century, with a view to making policy proposals from a new perspective, Mr. Masato Shintoki (former director of Climate Change Policy Headquarters in Yokohama City) and Prof. Hiroyuki Matsuzaki at Yokohama National Univerity started this project as representatives.

Overview of Center’s Activities

Aiming at “network-type research” by a group of volunteers who consider Yokohama’s fascinating urban development in a dedicated personal situation, research and practice will be promoted by three subcommittees based on global warming/ecological approaches, urban development/urban design approaches, and the energy approach. Through the Yokohama Marine Citizen College (about 20 times a year), we aim to realize citizen’s awareness, local contribution, and citizen’s participation while conducting discussions that transcend the boundaries of fields.

Subcommittee 1: Enjoy the beautiful sea, rich sea, and the sea (Head: Prof. Hiroyuki Matsuda)

Consider global warming measures from the viewpoint of the sea, and the world’s most advanced Marine Environment Future City. We are promoting activities on themes such as “Yokohama Blue Carbon”, “Reincarnation of Seaweed beds” and “Recreation”. (Subcommitte 1 home page)

Subcommittee 2: Environmental Ocean Mirai City Town Planning (Head: Prof. Tetsuo Kidokoro and Assoc. Prof. Taku Nohara)

Ever since the opening of the port, our town had always evolved against the background of “Sea” and “Port”, but it has lost these ties. We consider to rebuild “Town” from the perspective of “Sea” and “Port”. We consider a future vision of Sea-City Yokohama on themes, “Beach Atomosphere (Image, Resource, Sightseeing)”, “Utilization of Beach (Sea Shore) Space” and “Beach Industry”.

Subcommittee 3: Sea energy and community development (Head: Assoc. Prof. Satoshi Yoshida)

Regarding the sea as energy resources (sea breeze, sea temperature difference, wave force, tidal force, methan hydrade, etc.) or the energy as a seed to consider, we will consider how to utilize them in community development based on industry-government-academia-university cooperation. We considered how to utilize the renewable energy at Yamashita Wharf as a case study.

Yokohama Marine Citizen College (Assoc. Prof. Hirotaka Kawana)

Aiming at ocean-city-leader (“Umizoku”) development, platform creation for international marine environment city, and fostering an interface for ciizen-collaboration, Yokohama Marine Citizen College Executive Committee promotes workshops about 10 times per semester times 2, voluntary field works and researches.

Outlook and challenges for future activities

Regarding the method, system, activity mechanism, etc., the followings are issues for the future: the fact that we are proceeding while repeating trial and error, the relationship with the body organization (autonomy and industry), and the establishment of active base.

  1. Enhance the activities of each subcommittee
  2. Continuous development of Yokohama Marine Citizen College
  3. Accumulation of research information, regional information, and activity practice results
  4. Acquisition of a wide range of participants and construction of a cooperation network

Constituent organizations
