Los Angeles, CA – February 6, 2025 — MTN WTR Co, the pioneering brand behind the first Japanese naturally alkaline water in the U.S., continues its momentum since debuting in 2022. Driven by a mission of bringing “Good water for everyone,” MTN WTR Co introduces consumers to a uniquely soft and crisp water experience rooted in centuries of Japanese heritage.
A Legacy Rooted in Japan’s Purest Water Sources
MTN WTR Co’s story begins with Masa Kinemuchi, a native of Japan who spent his childhood immersed in the country’s highest-quality water. Coming from a family with a 200-year legacy in rice farming, Masa was taught:
“If the water is good, the rice, the sake, the land, and the health of the people will all be good.”
This principle instilled in him a profound respect for water as the essence of life and health. For over two decades, Masa showcased Japan’s finest products internationally while questioning why Japanese water—so integral to world-class sushi, ramen, and sake—wasn’t enjoyed more broadly around the globe.
After settling in the U.S., Masa partnered with water distribution and logistics expert Takashi Nakamura to form MTN WTR Co in 2017. In 2022, they successfully launched MTN WTR nationwide, delivering North America’s first taste of Japanese naturally alkaline spring water sourced directly from the slopes of Mt. Fuji.
