I've been playing maimai, the Japanese arcade rhythm game for a while. It offers a song named 天火明命, which a few of my friends pronounce as 'ten-ka-mei-mei'.
However, the official Twitter account of the game specifies it as 'a-me-no-ho-a-ka-ri' (あめのほあかり), which confuses me.
So what's the right way to pronounce the name? Is the "official" pronunciation simply the author's preference, or has actually been used in the past?
