ITM has been my "home" airport for nearly three decades. For years it didn't change and felt frozen in the 1970s. You could literally walk in the door 30 minutes before departure and catch your flight with time to spare. If you had a domestic flight with a change to an international flight in Tokyo, then maybe 40 minutes. Haven't departed from there for a while, but arrived there a few times recently. Now, you exit baggage claim/terminal area on the second floor. If you have bags on a cart, it's a hassle to get to the first floor or over to the parking garage. In old days, exit was on first floor about 20 seconds from the street. Still though, a convenient airport all in all in my opinion.
Kobe airport is wonderful. Get off the monorail and walk onto the plane. Feels more like a train station than an airport.
