Japanese marine scientific research under United Nations Convention on the Law of the Sea

This work qualitatively surveys tendency of duties or requests, which foreign States imposed with consent for a Japanese research organization to conduct marine scientific research (MSR) in foreign Exclusive Economic Zones (EEZ) in accordance with United Nations Convention on the Law of the Sea (UNCLOS). MSR conducted only in 1999 or later was reviewed. The most common request is for cruise reports. In terms of requests of cruise reports and data or samples, few coastal States changed. Recently, slightly fewer States request embarkation on a research vessel as a right based on UNCLOS than before. Increasing number of States require a particular application format.
