(I can't recall seeing them near the DL gates in Terminal 1 and AFAIK the other side of Terminal 1 is entirely *A.) Changing terminals at NRT is a hassle and time consuming; you must take the specific airside bus for your carrier and these buses are not very frequent. (They also stop service outside of prime hours.) The gate with these buses reminds me of the worst sort of set-up for small planes without jetways, where a bunch of flights share the gate at the same time.
CI is in the old and hot (in the summer, due to lack of AC) and cold (at this time, due to lack of heating) Terminal 1. From my experience, T1 to T2 is just a walk. If you keep walking long enough in T1, all of a sudden you will walk into what looks like a different airport: cool (not stuffy and uncomfortably hot), more modern design, clean, pleasant. Right after you see the sign: Terminal 2. It's just a looong straight hallway where if you keep walking, you walk from T1 to T2.
And again, CI is at T1.
EDIT: this is talking about TPE (Taoyuan airport, Taiwan), not NRT (Narita, Japan).
