Flying to NRT, but short time only in clubhouse

Hi All
I will be fling to Tokyo in the next few weeks, but the documentation says that check-in for flights to Tokyo opens 2.5 hours before the flight leaves. This means that I won't have too much time in the Clubhouse before we depart. I had planned to have a relaxed treatment, food, pool and drink before the flight.
Does anyone have experience of this late check in for Tokyo? Most other flights open 4 hours beforehand. Do you know any way I can check in at 9am instead of at 11am?
Thanks
