Arctic Research Vessel Overview

Background on the Arctic research vessel

The Arctic faces many difficult challenges, including environmental changes that have led to the loss of sea ice; we need to learn how to manage the increased economic activities resulting from these changes. These environmental changes are causing far-reaching effects, some of which are seen as extreme weather systems outside of the Arctic region, e.g. extreme snowfall occurring in Japan. As such, the changing Arctic environment is really a global concern.

Japan, as a nation affected by these changes, and as a world leader in scientific research, has a responsibility to form a commitment to scientific investigations into the changing environment of the Arctic.

Japan is building an Arctic research vessel with icebreaking capabilities and world-class scientific facilities to fulfill these commitments. This research vessel will promote the importance of Arctic science and work towards sustainable development of the Arctic region.

Furthermore, Japan remains committed to developing the next generation of scientists and engineers to utilize this research vessel and plans to develop further and deeper collaborations with our international partners.
