Winter Bus Tozawa-ko / Nyuto Onsen

Hi,

I'm wondering if anyone knows the bus timetable around Tozawako / Nyucto Onsen for winter season. I've visited the japan-guide website for Tozawako and apparently it says that during winter season, some bus lines may be closed. If so, would these areas still be worth visiting? And, how many night(s) would you recommend staying in Tozawako area?

Thank you very much in advance!

What is "Tozawako"?

@Firas: Tozawako must be is Tazawa Lake plus a typo. The lake just below Nyuto Onsen.

Here a link to their web page. I did not find an English version, but maybe there is one:

You can select the bus route from the map. The sentence at the top of the page says that betwen 29 Dec and 3 Jan Sunday timetables will apply.

Enjoy your trip to Japan!
