Mine is taller, has more heft and blade heavy balance compared to my Toyama - Kawachi is a bit less convex and is less MANTOKUishThey’re great, very tall and great for a midweight. Not sure if they’re quite as much heft as Toyama but still great
Here is my Toyama on top of my Kawachi - the edge profile is he same
Distal taper is similar as well
