Why Japan adopted kamikaze attacks

What led Japan to use kamikaze attacks in World War II?

Resource management and accuracy: suicide attacks were intended to make scarce sorties more likely to score a hit.

Two concise drivers explain kamikaze tactics: resource management and accuracy. Deliberately crashing an aircraft exchanged both machine and pilot for a much higher chance that the sortie produced a damaging hit. That logic sought to extract an effect from increasingly scarce offensive resources. Intimidation alone is an incomplete explanation for Japan's effort to make each remaining attack count.
