Arriving in Japan with an armload of suitcases is a doddle; you just go 
to the baggage forwarding counters, where, for a few hundred yen apiece, 
they will relieve you of your bags and deliver them wherever you choose 
at whatever time you choose.

What about arriving in the UK (specifically, Heathrow)? Is there a 
similar service? I've never had any need for one before, so I've never 
noticed, and I can't seem to find anything on Google (most of what comes 
up there is about excess baggage or commercial handlers for bulk).

Does anyone have any experience of this?

Thanks,

John
