TOKYO — The Japanese cabinet on Friday approved a record $79.5-billion defence budget for 2025 as Japan accelerates building up its strike-back capability with long-range cruise missiles and starts deploying Tomahawks to fortify itself against growing threats from China, North Korea and Russia.

The cabinet-endorsed draft defence budget marks the third year of Japan’s ongoing five-year military buildup under the national security strategy adopted in 2022. The defence spending is part of the more than $1.05-trillion national budget bill — also a record — that requires parliamentary approval by March to be enacted.

Japan is preparing to deploy U.S.-made Tomahawks late in the fiscal year 2025 as part of its ongoing effort to acquire strike-back capability with long-range missiles that can hit distant targets. The budget allocates $8.59 billion for the so-called “standoff” defence system that also includes long-range missiles, a satellite constellation and other arsenals.

The cost includes $16.4 million for the purchase and addition of equipment to launch Tomahawks from Aegis-class destroyers.

To reinforce its missile defence system, Japan plans to spend another $4.86 billion that includes purchases of interceptors and a mobile reconnaissance radar to be placed on Okinawa, where more than half of about 50,000 American troops are based.

Under the defence strategy, Japan aims to eventually double its annual military spending to about $90.8 billion, making it the world’s No. 3 military spender after the United States and China.

As part of the military buildup, Japan is pushing to strengthen its largely domestic defence industry by participating in joint development and promoting foreign sales.

For 2025, Japan plans to spend $2.88 billion to build three 4,800-ton new multi-purpose compact destroyers that require 90 crew members, less than half the crew size currently needed as a result of automation and labour-saving design — the platform Japan wants Australia to choose for their future frigates. They are upgraded Mogami-class destroyers equipped with long-range missiles, reinforced anti-submarine warfare functions and high stealth performance, officials say.

The destroyers built by Mitsubishi Heavy Industries are one of two candidates shortlisted by Australia for its Sea 3000 frigate project and is competing against Germany’s MEKO A-200 offered by Thyssenkrupp Marine Systems. Japan would jointly develop and produce frigates for the Australian navy.

The project not only serves to further deepen co-operation between Japan and Australia but contributes to enhancing Japan’s warship capabilities, Defence Minister Gen Nakatani said last month.

Japan, whose only treaty ally is the United States, has developed close ties with Australia and considers it a semi-ally as they face China’s growing threat in the region.

Japan is desperate to win the deal after it lost to France in the 2016 submarine deal with Australia. Prime Minister Shigeru Ishiba’s cabinet has already approved foreign sales of Mogami-class FFM to Australia in hopes it is selected, and set up a joint panel of government and industrial officials to step up its campaign drive to Canberra.

Japan is also jointly developing a next-generation fighter jet with Britain and Italy for deployment in 2035 and allocated $994 million in the budget for the project.

As the country’s population continues to shrink, Japan focuses on unmanned weapons and artificial intelligence to make up for the declining number of servicemembers and allocated $1.013 billion. Separately, the budget also adopted a plan to reinforce the “human base” by significantly improving salary, working conditions and support for career paths for the Self Defence Force to attract more applicants.
