in the past couple years,on our two visits to japan, my wife and i have had lunch or dinner in over 50 Michelin starred restaurants in tokyo or kyoto or osaka. some in private rooms, some at the counter. never a request for jacket.

almost all wanted one day advance notice(to procure fresh foods)

we were almost always the only caucasians in the restaurant. the table guests almost always engaged us in conversation as they wondered how we found the place, and how we liked it. there was a lot of excellent english available, as my wife and i do not speak japanese.
