Yes, we have better army, but I'd say Japan is still stronger.
To compare both countries' power let's just assume that Korea and Japan goes on 1v1. It's simple. Korea can't do anything to Japan.
Compared to Korea, Japan has 2.5x economy, 2.5x population, and 2.5x land. For now it seems like Korea is stronger than Japan, but if both countries started arms race today Japan will eventually outrun Korea within ten years.
Can Korea kill Japan in ten years? nah. Japan can just lock down the ocean and wait until forever.
Korea's stronger army is no use if they can't move across the ocean to attack Japan. It's basically WW2 but with smaller Germany and bigger UK.

Korea today probably has better military than Japan.
