During World War II, was Japan’s tactical thinking very backward?

During World War II, Japan's military tactical thinking was lagging behind other countries in some aspects.

The Japanese military primarily used melee weapons and small arms, often treating soldiers as substitutes and expecting to sacrifice themselves to win.

This makes them perform poorly in some large-scale operations, but it also leads them to demonstrate extremely high survivability and adaptability in various harsh environments, such as fighting in dense forests and jungles.

In addition, in the fields of navigation and submarines, Japan's tactics and technology are relatively advanced.

The Japanese navy, dominated by fast maneuvers and large battleships with long-range firepower, achieved a series of stunning victories.

Japan's submarine technology is also very advanced. Their submarines attacked a large number of Allied ships during the Pacific War and became an important tool in Japan's aggressive operations.

In general, Japan's tactical thinking may lag behind other countries in some aspects, but is very advanced in other aspects.

Japan's failure in the war was partly due to their strategic and political mistakes, rather than purely tactical and technical reasons.
