One of the most notable attempts by Japan towards fostering regionalism in recent years has been through its active and positive participation in the East Asia Summit (EAS), envisioned to be a stepping stone towards the formation of an East Asian Community (EAC). The idea behind regionalism and efforts towards the EAS and EAC are to be perceived within the broader context of Tokyo's attempts to shape the regional environment and influence policies in the region. Its primary goal is to neutralize and dilute the influence of China.

The Self-Defense Forces (SDF) are one of the variables of the distinctly pacifist security policy Japan has followed ever since the end of the war. Japan's ongoing 'normalisation' involves an enhancement of the role and functions of these forces. Although the SDF's role has considerably increased in the past decade, it cannot be characterised as Japan's remilitarisation because of strong domestic and external checks.

Contemporary Japanese nationalism is the principal force behind Japan's gradual shift towards 'normal' statehood and what has been called as 'reluctant realism'. The nature and content of this nationalism is, however, very much dissimilar to that which characterized its militarist past. This nationalist streak is largely elitist and assumes softer undertones as it percolates down to the masses.

The recent nuclear test carried out by North Korea in defiance of warnings by the international community has significantly raised Japan’s security concerns. The test conducted on October 9, 2006 made Pyongyang the second nuclear weapon state in North East Asia after China. It was carried out in the backdrop of already heightened tensions in the region following a set of multiple missile launches by Pyongyang on 5 July 2006. The missiles which had plunged into the Sea of Japan, had even evoked calls for preemptive strikes from a section of the political and defense establishment in Tokyo.

Japanese foreign policy and security perceptions have undergone a perceptible and steady change over the past decade, especially under the leadership of former Prime Minister Koizumi (2001-2006). Its support for the US war on terror was a significant step in its growing international politico-security profile.
