katakana comes from parts of chinese hanzi characters which usually consists of two parts called 'radicals', the meaning character and the pronunciation character. the chinese characters themselves look sharp because they mixed with old turkic scripts when developing new standard chinese characters after old chinese which looked more primitive. hebrew also has relations to turkic script due to co-evolution from aramaic (which later became arabic). in china today the biggest remaining turkic group are the uyghurs. there could also be something to say about how japanese and korean languages themselves are similar to turkic for similar reasons, but with the script it first came through chinese.
