I took the bus there. You need to make sure that you get on the correct bus because they go to different locations. It will be the last stop on the bus and after you have 40 min until the next bus arrives .
Waterfall is top 100 in Japan. And it’s definitely impressive
Beautiful and accessible view of the waterfall. There’s also a bus stop nearby (with only 4 buses each direction per day). The other option is to walk 4.5 Km to Kuriobashi station.
