No, but in a high-end restaurant, it is only certain that you will have trouble
because you just don't know the right table manners of Japanese foods, no one laughs you, though.
This is a short film of shabu shabu, useing expressions a little exaggerated,https://youtu.be/ilmx0EesGZchttps://youtu.be/fXWQ9yKq3S0
but it is "common sense" for Japanese that humanity comes out in table manners and more.https://www.youtube.com/results?search_query=japanese+table+manners
Anyway, both dishes are easy to make at home without using high-grade ingredients.https://www.youtube.com/results?search_query=how+to+make+sukiyakihttps://www.youtube.com/results?search_query=how+to+make+shabu+shabu+a...
Basically, pot dishes(read wiki) in Japan are surrounded by several people, so conversation also gets fun.https://en.wikipedia.org/wiki/Nabemono
In other words, like a party meal, so it is the same as several people eat a big pizza.
Sukiyaki main character is meat(beef usual, but pork and chicken also used),
but shabu shabu is also used "fish" instead of meat, "Tai(=sea bream) shabu" and
"Buri(=amberjack) shabu" are very famous, also dismantling work of fishes is not so hard.https://www.youtube.com/results?search_query=%E9%AF%9B%E3%81%97%E3%82%...https://www.youtube.com/results?search_query=%E3%83%96%E3%83%AA%E3%81%...
(I might explain about good taste fishes at another Q, if someone posted.)
If you really want to eat alone without being disturbed by anyone, you can order it
"room meals" at mid or high class Japanese ryokans in Onsen town cheaper than mid Tokyo.https://www.youtube.com/results?search_query=ryokan+food+japanhttps://www.youtube.com/results?search_query=ryokan+sukiyakihttps://www.youtube.com/results?search_query=ryokan+shabu+shabu
If you see the related videos thums, you can also find people eating alone at mid Tokyo.
Also you can. https://gurunavi.com/
More than listed in Japanese version, but staffs who can only speak Japanese including,
so I think that this is enough for beginners, not only hi-end ones, no worry.
I think that you are surprised at the quality and seasoning of the meat and more,
but if you come from a country where you do not eat "raw eggs", that one might be impacted.
I do not know how many times you ate "genuine" Japanese foods.
You may be proud of if you are caught in Japan by this Japanese guy.https://goo.gl/iXnfXU
