Engine manufacturer Rolls-Royce has initially stationed two spare Trent 1000 powerplants in Tokyo to support the service entry of Boeing's 787 with Japanese carrier All Nippon Airways (ANA).
R-R will increase spare engine inventory in the country as further 787s are delivered to ANA, said Trent 1000 programme director Simon Carlisle.
It has a service team of seven people based in Tokyo to support the aircraft, alongside round-the-clock on-wing monitoring of the engines from its Derby headquarters.
ANA is due to begin revenue service with the 787 later this month.
R-R has firm orders for 266 Trent 1000s alongside 66 options, with the majority of customers, except ANA, choosing its Total Care support package.
