TOKYO >> Japan’s Cabinet on Friday approved a $6.8 billion request for an extra defense budget through March to expedite the purchase of missiles, anti-submarine rockets and other weapons amid rising concern over the escalation of military activities by China, Russia and North Korea.

The request, still pending parliamentary approval, brings Japan’s military spending for the current year to a new high of more than $53.2 billion, up 15% from 5.31 trillion yen in 2020.

The Defense Ministry says its “defense power reinforcement and acceleration package” is designed to speed up deployment of some of the key equipment from the 2022 budget request. The goal is to beef up Japan’s defenses against North Korea’s missile threat and China’s increasingly assertive maritime activity around remote Japanese southwestern islands, officials said.

Japan has also raised concerns over recent joint military activities by China and Russia near its waters and airspace.

A fleet of two Chinese H-6 fighters and two Russian Tu-95s flew from the Sea of Japan to the East China Sea and to the Pacific Ocean, triggering Japanese Self-Defense Force jets to scramble, Defense Minister Nobuo Kishi said Tuesday.

The budget request includes nearly $870 million for the advanced version of PAC-3 mobile surface-to-air missile interceptors and related equipment, as well as cruise missiles.

Separately, more than $7 billion will go to speed up the purchase of reconnaissance planes and equipment, including three P-1s, equipment for P-3Cs and vertical launch systems to be placed on two destroyers, to step up surveillance around Japan’s territorial waters and airspace.

Japan has been stepping up defenses in its southwestern regions and islands, including Ishigaki Island, where a new military base with a land-to-sea missile defense system will be operational. Ishigaki is north of the uninhabited Japanese-controlled Senkaku Islands, which are also claimed by China, which calls them Diaoyu.

Tokyo regularly protests the Chinese coast guard’s presence near Senkaku Islands.

The ministry also plans to build housing for ground troops on Ishigaki Island.

The combined budget for 2021 will be just over 1% of Japan’s GDP, keeping its customary cap. Prime Minister Fumio Kishida has said he is open to doubling Japan’s military spending to cope with the worsening security environment.

The defense budget also aims to ease the burden on Japanese defense equipment and parts suppliers that are struggling to maintain the country’s dwindling industry, officials said.

The defense budget is part of a nearly $316 billion draft extra budget approved by the Cabinet Friday to fund an economic stimulus package focusing on COVID-19 preparedness and support for the pandemic-hit households and businesses. Some opposition lawmakers criticized Kishida’s government for using the stimulus package to cover military spending.

Critics also say Japan, as the world’s fastest-aging country with a shrinking population, should allocate more money toward health care and other services.

Japan’s military spending and capabilities have grown continuously since former Prime Minister Shinzo Abe took office in December 2012, and has since risen by 17%. Abe’s government allowed Japan’s military to be more involved in international affairs by adopting a new interpretation in 2015 of the war-renouncing Article 9 of the constitution.
