Narita Taxiway Markings
 

Couldn't find any reference. Haven't seen them at any other airport. From their location either side of taxiway centreline it looks like it's connected with stopping position of aircraft main gear, maybe for de-icing, engine ground running etc. Must be a local marking that only those who work there know what it means.

Just a guess , but it looks like a cross section of 2 engines , as M90 said ,maybe engine run-up position ??

Or restricted to twin engine only, no wide-body four engine aircraft. Just a guess..

This way to the Cage perhaps?:E

I think that's on Taxiway W not P.

Just decorative, maybe?
