Ah. My favorite "facility." That's actually a massage table that'll give you different options--shiatsu, swedish and the like. Just turn off the lights, press a button, shake off that tension from your body, and snooze away.
The lift. Know where you're going. Don't be afraid to ask. Better yet, end those questions with a smattering of memorized Japanese phrases.
As you take your lazy strolls in Tokyo, you'll see a lot of small parks with a variety of fountains.
Traffic can be very bad, but still orderly. Go figure. The southeast asian and south asian countries can learn from this. Their cabs have those GPS machines. Make sure you have the address of your destination. The driver will punch it in and, voila!, you're off to wherever you wish to go. But taxi trips are ultra expensive. If you can figure out what those signs at the train stations mean, by all means, take the train. It's faster and you'll have a lot of options, with less probability to blow your limited budget.
Of course Tokyo is a travel hub. You'll see planes and carriers you never knew existed. And, yes, they have those massage chairs elsewhere in the airport, as well. For a fee, of course.
