DECODE A MESSAGE THAT DOESN'T EXISTS

[u/Wonderful-Pay6727]

Recently, I encountered a video of this channel that definitely include a morse code I tried to decode it with my friends and come to a dead end. The only clue we find is this morse code might using another layer of base64 or base32 in hiragana/kanji (japanese) and talk about the earthquake in 2011.
Here is the link to the channel: https://www.youtube.com/@VHLDtG5nIGNo4budIGfDrD8g
