Bessho Onsen train questions

Hello. I have a few questions about taking the Uedadentetsu Bessho line from Ueda to Bessho Onsen, if anyone has been and can help me.
Does the train have a restroom on it?
Does it stop at each of the 15 places listed on this website? It's hard to imagine that it does stop at these places if it's only a 30-ish minutes train ride. www.uedadentetsu.com/english/
(I have a person with accessibility issues in my traveling party, so these things would be helpful to know.)
Also, how often, approximately, does it leave from Ueda?--The timetable on the website is in Japanese.
Thanks for any help!

I am pretty sure that it does not, but I could not confirm 100%.

Yes, all trains stop at all stations.

Also, how often, approximately, does it leave from Ueda?

1-2 times per hour:

—> it’s only a 10 km ride. So 30 min is actually pretty slow.

Regarding toilet it doesn’t seem so. But there should be one at Ueda station.

Hi, it has been a few years since we went on that run, but yes it stops a lot, but the total distance is only 12km so essentially it isnt going very far or long at all between stops (from memory there is one section where it goes for a few minutes without a stop).

If it doesnt have toilets (I didnt notice) then you could always hop off at a station and get back on the next train, though some of those regional stations might not have toilets I suppose, so maybe check that before you do. Just looking online, Shimonogo station which is about half way has a toilet.

Bessho onsen station is really nice, when we were there I think in May the cherry blossom tree there was in full bloom.

Thanks for the help.
I'm also wondering--is this the best way to get from Ueda to Bessho Onsen? We will be coming from Karuizawa.

From Ueda to Bessho Onsen? The local train. From Karuizawa, I would go shinkansen to Ueda and then local train to Bessho Onsen. From memory Karuizawa to Ueda is only about 10 minutes or so.

Thank you all for your help!
