This is the best summary I could come up with:

By contrast, Japan's navy is vastly larger and its government is embarking on its largest military spending spree since the Second World War.

That is primarily about ensuring Japan is capable of responding to Chinese threats against its outlying islands and territorial waters — as well as the possibility of a wider confrontation involving Taiwan.

Japan's navy, at 150 vessels, is less than half China's size — but the expected purchase of 1,500 long-range missiles from the United States would give it the capability of sinking Chinese ships as far away as Taiwan.

Japan is also working with European countries on developing new fighter jets, building long-range drones and expanding the size of its armed forces in its largest military buildup since the Second World War.

Polls in the country suggest 70 per cent of adults now back greater investment in the military, as the balance of power shifts in the region.

The door isn't closed to that, but advocates of the increased funding argue Japan will be in a better negotiating and deterrence position with a stronger military as backup.
