Karuizawa help

Hello everyone,

I'm trying to plan my day in Karuizawa end of November. I want to visit these places in a day:
Ryugaeshi Falls
Shiraito Waterfall
Senga Falls
Onioshidashi Volcanic Park

but I'm having difficulty trying to find information about these places.

1. Is it possible to walk from Ryugaeshi falls to Shiraito waterfall, then to Senga falls?
2. Does anyone know if it's an easy/light hike?

3. Could someone help me understand the bus timetable to Onioshidashi?
Google maps doesn't provide me with a route to the volcanic park so I found these timetables but I don't understand it!

Adding to this, is there a bus stop between Shiraito Waterfall and Senga Falls I can take to go directly to Onioshidashi after?

Thanks in advance!

good morning

the above trail is part of a 11km popular trekking course (between Mikasa and Minenochaya bus stop) which is considered to moderately challenging.

If you're up for renting a car, I found out the hard way that Karuizawa is one place to do it. There are not that many buses, and you may have to wait a long time. In my case, I went to see Shiraito Falls by bus, and yes, it was worth it.

After that, I wanted to go to Onioshidashi, but there was no direct bus there. It's less than 10 km directly, but there were no taxis and it would take about 2 hours on foot. So I had to return to central Karuizawa to get another bus. I did manage to get there, and it was worth the effort.

But a lot of time was wasted in transport, and I had to wait a long time for the last bus to get back. For all the outlying places you add, just by bus and on foot, for a day trip I'd say your plans are too ambitious.

@anastasia and @Ken Thank you very much for your kind help - my day in Karuizwa would have been a disaster without this :)
Based on this, my new plan would be to rent a taxi for 4 hours to Onioshidashi Volcanic Park, Shiraito Waterfalls, and then back to Karuizawa town.
