Should you ever have access to a Japanese soaking tub, DO IT!
Our meeting was at the Hotel Kabuki and let me tell you..
If you have trouble sleeping, put in a 15-16 hour day and
sit down in one of these babies before bed.
Within SECONDS you are unconscious.
(Maybe you'd better bring an alarm with you, don't want to go under!)
The water is deep, and there's a perfect ledge to rest you head on.
Of course, tough to get out of when semi-conscious, but well worth the risk..
