‘Human Security’ in EU-Japan Security Relations from a Japanese Perspective
Human security was adopted by Japan as a main goal of foreign and defence policy. Japan’s efforts to put human security on the agenda, especially at the UN, led to discussion and adoption in the communiqués within EU-Japan summit meetings. The apex of the concept in Japanese policy may have passed, becoming a subject of development cooperation policy rather than a fundamental guiding principle of Japanese foreign policy

Southwest Intrusion of <sup>134</sup>Cs and <sup>137</sup>Cs Derived from the Fukushima Dai-ichi Nuclear Power Plant Accident in the Western North Pacific
Enormous quantities of radionuclides
were released into the ocean
via both atmospheric deposition and direct release as a result of
the Fukushima Dai-ichi Nuclear Power Plant (FNPP) accident. This study
discusses the southward dispersion of FNPP-derived radioactive cesium
(Cs) in subsurface waters. The southernmost point where we found the
FNPP-derived <sup>134</sup>Cs (1.5–6.8 Bq m<sup>–3</sup>) was 18°N, 135°E, in September 2012. The potential density
at the subsurface peaks of <sup>134</sup>Cs (100–500 m) and
the increased water column inventories of <sup>137</sup>Cs between
0 and 500 m after the winter of 2011–2012 suggested that the
main water mass containing FNPP-derived radioactive Cs was the North
Pacific Subtropical Mode Water (NPSTMW), formed as a result of winter
convection. We estimated the amount of <sup>134</sup>Cs in core waters
of the western part of the NPSTMW to be 0.99 PBq (decay-corrected
on 11 March 2011). This accounts for 9.0% of the <sup>134</sup>Cs
released from the FNPP, with our estimation revealing that a considerable
amount of FNPP-derived radioactive Cs has been transported to the
subtropical region by the formation and circulation of the mode water
