Ok, this is going to sound like a stupid question, but I'll ask it anyways. Are there two RCCs in NRT?

If so where are they both located? I only found one on my trip through there last week. It was just past the security screening check point for connecting passengers. It was relatively close to my SIN flight leaving from gate 26, but a good hike from the departure gate for my SEA flight (can't remember gate number).

If that is the only one, where the heck are the showers? Because I couldn't find any.
