He doesn't seem to put much effort into his playing and sometimes accidentally lets a ball in; however, since he's a starting member in Shiratorizawa, his abilities shouldn't be too low. Tendō has noted that Kawanishi has an eclectic and more analytical blocking style, which the third year's a little annoyed by. His playstyle is stated by Tendō to be "omnivorous". Kawanishi primarily uses read blocking during matches, but, when he's in the zone, he switches to guess blocking. During their match against Karasuno, he demonstrated commit blocking against Hinata. It's been said that he doesn't fight battles he cannot win.
Due to Shiratorizawa's Spartan-like training regimen, Kawanishi, like most of the team, has an above average amount of stamina. He can play long matches without getting noticeably exhausted.
Kawanishi's high game sense and intelligence factors into his read blocking ability. After seeing Karasuno's synchronized attack once, he's able to break apart and shut down their subsequent attempt at another. When he's upfront, he directs the three-man blocks.
By National Finals, he became an unpredictable and accurate server, being able to serve at corners and the next one clipping over the net, where both being service aces.

Of all the Shiratorizawa regulars, Kawanishi appears to get along the best with Shirabu, most likely due to being in the same grade level.
