PLEAST Inc. (Headquarters: Fukuoka City, Fukuoka Prefecture, President: Takashi Nagao) will open the EC site for natural low-deuterium water "Cooland LDW135" on April 15, 2026. Cooland LDW135 uses natural water nurtured by the Altai Mountains and is characterized by a natural deuterium concentration of 135 (±5) ppm. For the water you drink every day, we propose a new option for discerning individuals who want to be particular about the source environment, ingredients, and drinkability.
■What is Cooland LDW135
The main feature of Cooland LDW135 is that it is naturally occurring low-deuterium water.
While typical natural water is around 150 ppm, this product achieves a rare level of approximately 135 ppm. This water is glacial meltwater formed over many years around the Altai Mountains, naturally filtered through the earth's strata. Therefore, it is characterized by its clear taste free of impurities, a balanced natural mineral content, and high transparency.
Furthermore, it is processed non-heated and additive-free, with no artificial adjustments whatsoever.
Being natural water sourced from a managed water resource protection area is also a significant value of this product.

■Rare Sourcing Location: Altai Mountains Kulan River East Bank Water Resource Protection Area
The process of reaching the source of this rare natural water was itself extremely special and difficult.
The water source is a "harsh sanctuary" in a water resource protection area where sub-zero temperatures are the norm.
As a special protected area where water use permits are managed, activities and facilities are strictly controlled to prevent contamination from heavy machinery or large-scale development, and to keep industrial and domestic wastewater out. Therefore, it is not possible to build a factory directly above the water source; instead, a method that requires considerable time and cost has been adopted, involving the installation of a long-distance dedicated pipeline with freezing countermeasures.
This design, which transports water while preserving its quality without damaging the sub-zero natural environment, is by no means rational if only efficiency is considered. Nevertheless, this method was chosen to deliver the water's characteristics, created by natural conditions, without artificial alteration.
■Natural "Drinkability" Created by Nature
It is characterized by a natural drinkability with pH 7.6 and being a medium-hard water that is easy to incorporate into daily life.
Furthermore, it is mindful of mineral balance, including 34.6mg/L of calcium, making it a natural water suitable for those conscious of beauty and condition management, those who want to review their daily beverages, and those who wish to slightly elevate their daily hydration.
【Product Features】
Naturally occurring low deuterium concentration (135±5 ppm)
Using natural water from the Altai Mountains, it achieves a natural low deuterium concentration of 135 (±5) ppm. Compared to typical natural water, this is a low value, making it a rare natural low-deuterium water.
pH 7.6 (Slightly Alkaline)
This water has a slightly alkaline quality (around 7.6) close to the pH range of Japanese tap water and general bodily fluids. It offers a natural drinking experience for Japanese people with minimal discomfort.
Well-balanced Minerals
Mineral components such as calcium, magnesium, and silica are included in a well-balanced manner, not in excess. It lacks the "heaviness" or "grittiness" characteristic of hard water, designed for easy drinking as "daily water."
Everyday Drinkability
It has the characteristics of medium-hard to soft water with a mild taste and smooth mouthfeel. It does not interfere with the flavor of cooking, coffee, or tea, making it easy to incorporate into scenes such as morning, during work, or after exercise.
PFOS & PFOA Standards Cleared, PFAS Undetected
The Ministry of Health, Labour and Welfare has set a provisional target value for PFOS and PFOA combined at "50 nanograms per liter or less" for the water quality management target items.
Cooland LDW135 has been confirmed to be safe water that fully meets this standard.
