The government is working out emergency legal steps for prompt activation of a missile defense shield when signs are detected that an enemy is preparing to launch, according to government officials.
Under the emergency steps, the government would first convene the Cabinet and Japanese Security Council when threats are detected, and then issue a warning to the enemy that Japan will intercept the incoming missiles, the officials said.
Following the meetings, the authority to implement the missile interception system would be given to the commander of the unit in charge of missile defense under the Self-Defense Forces, they said.
These steps would ensure civilian control in dealing with possible missile attacks, while securing prompt counteractions by the SDF, the officials said.
Rapid action is necessary because a ballistic missile could reach Japan quickly after its launch. But there is also concern over granting full authority to the missile interception unit, as such a move could erode civilian control.
The government plans to revise defense laws to enable the steps. But it is unclear whether related bills will be submitted to the ordinary Diet session in January because debates on other bills aimed at unifying operations of the SDF's three service branches will be given priority, the officials said.
In November, Defense Agency Director General Yoshinori Ono proposed giving the prime minister the power to skip the Cabinet and Security Council meetings in mobilizing the missile interception system and giving advance authority to the commander in charge of missile defense.
