Where Does MTN WTR Come From?

MTN WTR is sourced from Mt. Fuji, nestled in the nature-rich village of Narusawa in Yamanashi Prefecture, Japan. It begins as rain and snow and spends decades moving slowly through volcanic rock, naturally filtered along the way. The result is a clean, balanced mineral profile—no additives—bottled in Japan at the source for a crisp, smooth sip.

MTN WTR begins as rain and snow that fall high on Mt. Fuji (1,400–2,700m), in the protected forests of Fuji-Hakone-Izu National Park. It starts clean and untouched—pure from the source.

Where the Journey Begins

Rain and snowmelt on Mt. Fuji seep into porous volcanic basalt and travel slowly underground for decades, naturally filtered through layers of volcanic rock.

From Mountain to Spring — Bottled at the Source

After nearly 50 years underground, the water collects in a natural spring aquifer and rises in Narusawa, Yamanashi as true spring water. We bottle it at the source to help protect freshness from bottling to opening.
