Idk, my impressions of Japanese swordsmanship is to have a really sharp blade and spending lots of effort and time to practice swinging the sword/s to repeatedly to get stronger and faster to surpass oneself in body, mind and will while turning everything into body memory.
Chinese swordsmanship seems heavily rely on their flashy/complex techniques in movement to confuse people in the early days and later go less flashy and more focused on the essential parts like swinging form/stance, attack power, speed and flexibility as they become more experienced.
However, most of the time.. systematic training can do better than being flashy and get k.o.'d in one quick, fierce and accurate hit.
