For the first time in nearly 30 years, Japan's Ground Self-Defense Force (GDSF) started nationwide exercises on Wednesday that involved all units — part of an attempt to boost deterrence and strengthen its capabilities amid China's ramped-up regional assertiveness.

The GDSF drills, including transporting supplies and testing communication systems, will be carried out until the end of November across the country, with the aim of strengthening the ability to defend remote islands.

The GSDF last conducted exercises on this scale in 1993 after the Cold War ended. This time, around 100,000 personnel, 20,000 vehicles and 120 aircraft will join the drills, which will also involve Maritime and Air Self-Defense Forces as well as a U.S. Army landing ship.
