喫煙コーナーの場所としては分かりませんが　私設❓かもしれませんが宮川沿いで3人の男性が吸っていたのは見かけました。 タバコを吸いたい気持ちは理解できますが　観光地では我慢してもらえると嬉しいですね

Yes, Osu Kannon Jinja

Yes. Free car park at the back of the restaurant.

Sounds like a fun trip. Since you are going mid-November, there is a pretty good chance you will encounter snow; so need to keep that in mind. Shirakawago-go is worth half to 3/4 of a day, no more. Assume you'd make this your first visit after arriving in Nagano, so you arrive late afternoon and stay the night. Next is Takayama, which is worth at least a day and a half visit.....probably two nights. Apart from the old streets and Morning Market, make sure to stroll the "temple walk" North of the city center and visit the float exhibition hall. Remember.....snow. Can't help from there.

Bonjour tout d'abord Je ne comprends pas votre remarque, n'ayant jamais parlé de "piètre qualité" !!!!!!!!!!!

You can even go shopping. I lived opposite the train station. The souvenir shops were still open until vety late.

This is basically a tourist district. There are a couple of stores offering sake for a minimal price. If you would like to visit the brewering process, that might not open in weekend.

which hotel you mean? Sanmachi Suji is a neighborhood with a lot of hotels. Well, as usual western room involve private toilet...

hi. i was there on a weekday -- all shops were open (however they start closing at 5pm). and yes there are a some sake breweries/shops where you can try all the different sakes (for very little money) and then buy your favourite. the hida village is reported to be a must-see; i did not have time to make it, so i cannot tell. my favourite visit in Takayama was Takayama Jinya, a museum of Japan's best preserved local government and public services' building from the Shogun times.
