Been there, done that! Had 5 & half happy years. Left about 2 months before they announced that the contracts were changing to full-time (I was on the 5 year one).
The language speakers are necessary because the pax are demanding it. If you are fluent with Italian & Spanish I would apply too, there are Milan/Rome to Narita flights, also a codeshare with Iberia that goes via Ams, so they need the Spanish for them. Also there were several Dutch crew.
Routes changed abit whilst I was there, we lost the RTW trips, and I'm not sure what's on the cards for SYD.
If you are successful, the training takes a little getting used to. 5 weeks in LHR then about 6 or 7 weeks in Tokyo (you stay in NRT then it's a lovely 2hr trip every morning & evening by coach to Haneda) Then it's a month of supernumeries - although that's only about 8 flights. Be prepared to go back to school! Slightly subserviant and don't battle the system. Most of all enjoy the culture. Go for it!
