The spring is categorized as a cold mineral spring rather than a hot spring, as it maintains a low, stable temperature year-round.
The carbonation is naturally occurring, resulting from volcanic carbon dioxide gas mixing with groundwater deep underground.
The water contains iron and manganese, which can lead to sediment buildup in containers if stored for long periods.
It is an official 'Fukushima Heritage' site, emphasizing its cultural importance to the residents of the Aizu region.
The water's pH level is distinctly acidic, setting it apart from standard alkaline drinking water sources in Japan.
The Natural Sparkling Water Well in Kaneyama is a rare public spring featuring naturally carbonated water that bubbles directly from the ground at a constant temperature. Located in the Ooyamagami Shrine compound, the water is known for its high mineral content and sharp, acidic taste. It is recognized as one of the '100 Famous Waters of Japan' for its pristine quality and geological rarity. Visitors can collect the water directly from the spout for consumption or use in brewing coffee or tea. The surrounding area is maintained by the local municipality to preserve the spring's integrity. The water originates from deep volcanic layers in the Tadami River basin, giving it a unique composition distinct from treated or factory-bottled carbonated waters.

Bring multiple clean, empty plastic or glass bottles to transport the water home.
Use the water to make 'sparkling' coffee or tea, which is a popular local culinary experiment.
Check the clarity of the water at the tap; if it appears cloudy due to recent rain, allow it to settle before filling.
Do not drink excessively if you have sensitive digestion due to the high mineral content and acidity.
Clean up any spilled water or discarded debris; maintain silence as it is a sacred shrine site.
