Japan just got a tiny bit closer to revealing how substantial its increases in defense spending in the coming years are expected to be.

The government’s annual economic and fiscal policy guidelines approved by the Cabinet on Tuesday did not lay out a specific numerical defense spending target for Japan — but it did offer a marker, referencing goals announced by NATO and two other U.S. allies and pledging to “transform the country’s defense capabilities within five years.”

This marker is expected to lay the foundation for a clearer target to be outlined in the country’s three key national security documents that are scheduled to be revised by the year-end.
