https://en.m.wikipedia.org/wiki/Japanese_wordplayWah Hah Hah hy is Sunao = 370, specifically the "su" part?
Thanks. I was too focused on Japanese numbering that I didn't think of the english number lol-https://en.m.wikipedia.org/wiki/Japanese_wordplay
su seems to come from surii; that is, from transliterating English "three" as surii, and then shortened to just su.
