A lot of people come there from far away to get the carbonated water.
Of course you can get it for free.

It is sold at the roadside drive-in `Michi-no-Eki Oku-Aizu Kaneyama'', and has recently become more common in various places throughout the Aizu region, so it must be popular.
Also, the moderate amount of fizziness apparently goes well with food, so it is used in a lot of high-quality restaurants in Tokyo and other places.
Furthermore, it has been used to entertain foreign dignitaries at the G7 summits held in Japan in the past.

I actually tried drinking it, and although it was a little pricey, the slight fizziness went down well, and it was delicious.
Please enjoy the Tadami Line while drinking it.
