INTRODUCTION The original proposal of the research plan was drafted and submitted to the Secretary to the International Whaling Commission (IWC) and the Chair of its Scientific Committee (SC) on 18 November 2014, in conformity with paragraph 30 of the Schedule to the ICRW and Annex P (IWC, 2013b). Subsequently it was reviewed by the Expert Panel in February 2015 (NEWREP-A Review Panel), and then additional materials (in the form of ‘preliminary response’ and ‘addendum’) was reviewed by the IWC SC at its 2015 annual meeting from May to June, 2015.. The research plan has been now finalized taking into account the comments and suggestions on scientific aspects provided by experts inside and outside the IWC SC, in particular those from the NEWREP-A Review Panel, and from the IWC SC members. This research plan forms the basis for the Government of Japan to issue a special permit, in accordance with Article VIII, paragraph 1, of the International Convention for the Regulation of Whaling (ICRW). Even after the research plan is finalized, the proponent always welcomes comments from outside on this plan that are based upon scientific consideration to which it will give due regard. Furthermore, this research plan could be revised in relation to the lethal sample size, depending on the results of the analysis of non-lethal research methods detailed in Section 4 below. 1.1 Importance of scientific research in the Antarctic Ocean The Antarctic Ocean has its unique marine ecosystem and has the potential of its abundant living resources that could be sustainably exploited for food and other purposes. In recent years, the surrounding Antarctic region has been substantially affected by climate change and the resultant fluctuations in the oceanographic environment are known to have influences on the global environment. The Antarctic marine ecosystem is defined in Article 1, paragraph 3, of the Convention on the Conservation of Antarctic Marine Living Resources (Convention-CAMLR) as “the complex of relationships of Antarctic marine living resources with each other and with their physical environment”. This effectively means that it is composed of and made from complex interactions among the Antarctic Ocean, its circumpolar currents, sea ice formations and biota including 17 species of cetaceans. Among these, blue (Balaenoptera musculus), fin (B. physalus), humpback (Megaptera novaeangliae), and Antarctic minke (B. bonaerensis)
