Correct! My flight docked at A30 the other day but we had to get on a bus to International Arrivals B because we arrived from a wrong country (UK). No sign of a limo for this Cessna HON.

LH flights in NRT are now banished to gate 45 right at the end of the pier, a bus might not be a bad idea. But you don't expect a limo ride to the centre of Tokyo for under €30, do you?
