Abstract Using a case of the Sekisei Lagoon, Okinawa Prefecture, the southeastern tip of Japanese archipelago, this chapter discussed the interrelationships among
the sectoral policy interventions by various marine-related ministries, and the
whole structure of the integrated ocean policy. First, we developed the SocialEcological Systems (SES) Schematic, which summarized the main ecosystem
structures, functions, use types, and the stakeholders relating to the Sekisei Lagoon.
Then, sectoral policy interventions by various ministries were overlaid onto the
SES schematic to graphically show their interrelationships. We found that the ecosystem structure and functions used by one sector is closely connected to other
structures and functions, which are then used by other sectors. In other words, all
the stakeholders in the social system are closely interlinked at the ecological system level. Secondly, all in all, sectoral policy interventions by various ministries
are covering almost all part of the Sekisei Lagoon SES, and therefore, the total
coordination of the sectoral policy interventions and the creation of the synergy
effects are required. In this process, the cabinet office and the local government
