It's obvious Yhwach is a reference to the Tetragrammaton.

If Kubo wrote it that way, it wasn't because of censorship rather than we just wanted to write it that way. Generally, the Japanese really don't care about religion and know too little about Judaism or Christianity so I believe he doesn't get censored in these areas.
