Is it possible to have something like a mid 18th Century version of the Meiji Restoration and a rapid modernaization of Japan? I find myself tickled by thoughts of the Enlightenment esp. Voltaire coming to Japan and still more by the idea of a Japanese triple decker ship of the line. If this idea is as impossible as say Axis Wins WI's please make it clear why. If on the other hand there is some possibility in this TL and you are comfortable with Japanese history feel free to Enlighten.
