This is great news! I follow the Japanese fandom on Bluesky and it has grown a lot since January, especially after Hazbin Hotel came out, and I've seen several fans complain that they can't quite get into it because they aren't used to subtitles (you can find HB with Japanese subtitles on YouTube and NicoNico) and would rather watch a dub. I didn't think they would ever actually make an official Japanese dub, though!
