Decoding Japanese METARs

Anybody know what the items "1ST005 4ST010 7AC100" mean in the remarks section of the METAR below?

I think it’s an expansion of the METAR giving cloud type and cover in octas. 4ST010 = 4 octas stratus at 1,000’, 7AC100 = 7 octas altocumulus at 10,000’...

That makes sense, thank you!
