Japan accelerates defence buildup as JS Nagara is handed over amid China-related tensions
Japan has increased its defence spending to a record high as it steps up a broader security overhaul shaped by concerns about China, North Korea and Russia. The latest development came with the official handover of the newly built warship JS Nagara to Japan's self-defence force. During a speech on the vessel, parliamentary secretary to the defence minister Yoshida Shinji said the move was needed to safeguard the country's territory.

Mr Yoshida said the security environment around Japan was now the most severe and complex it had been since the end of the war. He said the JS Nagara would help meet increasing demands for surveillance and monitoring in peacetime. He also said the ship had anti-submarine, anti-air and anti-surface warfare capabilities in the event of an emergency.
The remarks underline how Japan is presenting the ship not only as a symbol of renewal, but also as part of a wider operational shift. The warship handover comes as Japan continues to expand several parts of its defence posture. The country is moving weaponry to its outer islands, developing a new cybersecurity strategy and working on a national intelligence agency.
It has also changed rules to allow the sale of military equipment to certain countries, with the Philippines and Indonesia already making deals. Japan's latest budget allocates 9 trillion yen, or about 80 billion dollars, and is close to its goal of spending 2 per cent of gross domestic product on defence. The changes matter because they mark one of the most significant shifts in Japan's security policy since World War II.

For decades, Japan's post-war constitution and political culture placed strong limits on military activity, but those constraints have been under increasing pressure as regional tensions have grown. The current buildup is being driven by what Japanese officials describe as a more severe environment, especially as tensions with China have escalated over Taiwan and maritime activity in nearby waters. Japan's position is shaped by geography as well as politics.
It is surrounded by nuclear-armed China, North Korea and Russia, and has faced repeated pressure to strengthen its defences. The United States, Japan's only official ally, has also urged Tokyo to raise defence spending, while Washington's attention is increasingly divided by other global crises. That combination has helped push Japan toward a more assertive security posture, including greater surveillance, stronger island defences and more advanced military procurement.
The JS Nagara also has significance beyond Japan's own forces. Australia has already agreed a multi-billion-dollar deal to buy warships based on an upgraded version of the same class, showing how Japan's defence industry is becoming more relevant to partners in the region. The shift has been welcomed by Australia and the United States, but heavily criticised by China.
It also reflects a wider effort by Tokyo to build capabilities that can support both deterrence and day-to-day monitoring. The latest spending increase and the commissioning of JS Nagara fit into a longer pattern of gradual but steady defence expansion over more than a decade. What is new is the scale and pace of the changes, which now include cyber, intelligence and outer-island deployments alongside traditional naval and air capabilities.

Japan is also trying to balance those moves with its constitutional and political constraints, which remain an important part of the domestic debate. What remains unclear is how far and how fast Japan will go in turning these plans into fully operational capabilities. It is also not yet clear how China and other regional powers will respond to the latest steps, or whether further budget increases will follow.
