There is no mistaking Japanese Prime Minister Shinzo Abe's determination to transform the nation's foreign and security policies and reassert itself in the world. In the four months since he took office, he has made considerable progress in that endeavour.
Yet he is conducting a delicate balancing act that is becoming more difficult as he moves forward. While he must seize opportunities as he forges this new role, he must also reassure doubters both at home and abroad that Japan will act responsibly. That requires a vision of Japanese power and a national strategy to use it. While the primary burden is Tokyo's, Washington, as its ally, can play an important role.
Mr Abe has pushed his 'transformative' agenda since becoming prime minister, quickly visiting Beijing and Seoul in an attempt to reverse deteriorating relationships.
Japan also has taken the lead in UN diplomacy to respond to the North Korean missile and nuclear tests, and Mr Abe has reignited Japan's bid for a UN Security Council seat. At last weekend's East Asian Summit and related meetings, Japan offered US$2 billion to help developing countries in the region adopt more energy-efficient technologies. And it continued efforts to consolidate economic relations with Asean and to assist with maritime security.
On January 9, the Japan Defence Agency became the Ministry of Defence, a long overdue development that could rebalance bureaucratic politics in defence decision-making. Other security policy changes are under way.
The creation of the defence ministry occurred on the eve of Mr Abe's departure to Europe, which included a historic speech to Nato, the first by a Japanese leader.
In his speech, Mr Abe vowed to take a more activist approach to foreign policy. 'While adhering to the principles of the constitution, Japanese will no longer shy away from carrying out overseas activities involving the [Self-Defence Forces], if it is for the sake of international peace and stability,' he said. He also underlined the potential impact of problems in countries such as Iran, Sudan, Afghanistan and Iraq. This is especially important, given the traditional restrictions limiting Japanese activities to 'situations in areas surrounding Japan'.
