That’s a great rundown on our transfer options, tauphi. Absolutely corrrect, we are arriving Terminal 1. Thanks for letting us know about the airport bus not servicing that Terminal.
If our initial flight is delayed this sort of information will really help us secure assistance in Japan (where I expect it may be easier to get the airline’s co-operation)

Taxi is definitely last resort for us. It doesn’t matter how hard I try I can’t ever seem to stress enough how much we hate and will avoid using them.
