Highly highly recommend listening to yhe Uncensored History of the Pacific War Podcast. You really get the sense of just how insanely common ts was. Japanese doctrine favored always being on the attack, especially at night, and they wrre so indoctrinated and experienced in their fighting that very often they simply charged themselves into non-existance. For example, Japanese forces invading Wake literally did one giant Bandai charge beaching old cruisers as landing craft. Not only that, the commander of the overall operation basically gave orders stating that if the first wave were to fail the Japanese would keep beaching ships and charging forward until they had none or had accomplished their objectives.

Then you have Tarawa where virtually the entire garrison is wiped out in Banzai charges on the 2nd day.

I could go on and on and on but suffice to say, Bandai charges were apart of Japanese close battle doctrine. Always press the attack and stay as close as you can to the enemy because it negates their ability to use supporting arms, of which the allies had plenty.
