Human Factors
During climb off 16R (RJAA) on the Cupid departure we were initially assigned 9;000 feet per departure control. We got a clearance direct Cupid intersection and climb to 10;000 feet which was read back. I reported 'out of 9;000 for 10;000' because I noticed traffic on the TCAS opposite direction at 10;000. ATC responded with a clearance to maintain 9;000 feet and turn right immediately to Hdg 180. The First Officer (PF) complied however we reached 9;400 feet before returning to 9;000. We did get a TA but not a RA and with the traffic in sight; there was no near miss as some passengers and flight attendants believed.
[Report narrative contained no additional information.]
Flight crew of a widebody transport cleared to a conflicting altitude during departure from RJAA resulting in a TA alert. Crew complied with a new cleared altitude and thus cleared the conflict.
