Theme: Bamboo trim, fake-stone walls, and orchids. If there’s any remaining doubt you’re in a ninja lair, there are yin yangs on the doors to emphasize the point.
Privacy: Best in the handicapped loo. Don't even think of trying the “Staff Only” doors — they lead to ninja changing rooms. And if you see them without their ninja garb, they'll have to kill you.
Amenities: The Toto toilet’s seats don’t seem to lift automatically like Morimoto’s, but there are remote-controlled “rear cleaning” and “front cleaning” streams, and a hot-air dryer.
Drawbacks: It takes a while to realize that the front-cleaning jets don’t turn off automatically. Then again, you might not want them to.
Strategy: Can’t find the bathrooms? Ask a ninja!
