So as a buyer who can't read Japanese it's really difficult tell what the softness scale is on quite a few products. Aside from the ones that obviously state it.
It'd be cool if the site had some sort of consistent scale of hard-soft for reference with descriptions.
Like HotPowers toys have a scale of -4 to +4 and the pictures definitely match fo easily understanding the scale.
However ToyHearts is this color wheel that reminds me of the goggle chrome logo, and Orange means very hard... i think.
I honestly can't tell, given that reviews of their products don't seem to match any one color selection being more hard than the other's.. at least not consistently.

I'm sure this might seem like a dumb complaint, but it's certainly pretty confusing.
