But in an archive thread they mentioned that the chinese had written records of some group from Mu turning up in japan.
Wouldn't that point to a more recent event?
I don't know more than that I was randomly flicking through 4plebs at the time.

Idk about that but Chinese history is truly ancient as they developed very early (and then stagnated for millennia because while China is highly fertile, it is highly vulnerable to invasion and natural disaster). Then you have people writing down oral history so they do have the capacity for very old records.
The Chinese have always been good sailors because the Yellow River is very vast, very wide and carries a lot of sediment, and lowland China is very flat. The Yellow River has changed its course and mouth dozens of times in the last 3,000 years and was their primary waterway, so the Chinese ended up all over the place. 
TL;DR: I don't doubt it at all

Pic related, where I reckon Mu most likely was given sea level rise over the last 12,000 years and common myths in SEAsia.

There's an Indonesian man that made a good case that this area (Sundaland or Sunda plain) was Atlantis. He points out the size matches the description (Libya and Asia minor combined). Also Atlantis had two growing seasons, spices, and elephants, placing it in the tropics or subtropics.
