There is a dedicated parking lot along National Route 252, which runs through Kanayama town, and the Oshio Natural Carbonated Water Spring is about 200 meters from there, which is about a 5-minute walk

It's easily accessible because it's a fully paved road, not a mountain trail or a steep, winding path

The site is a large open area with several chairs and tables set up
Water collection facilities, such as wells and water drawing points, are located along the mountainside visible in the background of the photo above

The well is about 4 meters deep. Most of it is sealed off to prevent falls, with only one opening that can be opened and closed. This might be a good option if you want to take home a larger quantity of water in a plastic bottle

Next to the well, there's a separate water-drawing station that's easy to use. If you just want to sample a little, this might be more convenient
