In a nutshell, JAL is planning on displaying pieces at Haneda airport of the 747SR that crashed in August, 1985, after a bulkhead ruptured.
It sounds, at least, as though the display will not be in the central terminal - I can't even imagine that - but in a separate facility.
Since it is where most airline employees will be able to see, I think that at least is a good idea. Will it draw many other visitors? Time will tell, I guess...
