天然のアルカリイオン水
In its healthiest state, the human body naturally maintains a stable, slightly alkaline environment. However, modern lifestyle disruptions can cause our internal pH to lean towards acidity. This shift has brought "Alkaline Water" into the global spotlight as a vital wellness solution.
Onsensui 99 is a natural alkaline ion water, uniquely filtered through the prehistoric volcanic layers of the Shirasu Plateau, formed by the eruptions of Mt. Sakurajima. Notably, as approximately 60% of the body’s immune cells are concentrated within the gut, alkaline water is widely recognized for its restorative effects on gastrointestinal health and balance.
While standard drinking water typically maintains a neutral pH of around 7, Onsensui 99 boasts a pH of 9.9—reaching the pinnacle of alkalinity on a global scale. Beyond its superior pH level, its exceptional "permeability" ensures that the water is absorbed into the body with maximum efficiency, hydrating you at a deeper cellular level.

リラックス効果&健康な体づくり
The human body’s water content drops significantly with age from 80% in infants to just 50% in the elderly. As we age, our thirst reflex weakens, leading o "silent dehydration" that disrupts circulation and health.
Establishing a habit of sipping high-quality water is a vital investment. Proper hydration not only stabilizes physical health but also provides a calming, relaxing effect on the mind.
Since water is a daily necessity, choose the finest. Onsensui99 serves as your "Functional Wellness Water," supporting your vitality from the inside out.


常温でもゴクゴク美味しい
Water is categorized into "Hard" and "Soft." Most Japanese waters are globally acclaimed for being "Soft Water," with a typical hardness level between 20 and 100. However, Onsensui99 exists in a league of its own with an incredibly low hardness level of only 1.7.
As a true "Ultra-Soft Water," its texture is remarkably smooth and mellow, with a subtle hint of natural sweetness. Generally, the lower the hardness, the smoother and more delicious the water becomes. Onsensui99 redefines what "pure and easy to drink" really feels like.


潤いを保つ水分補給のススメ
The water inside us functions as blood and lymph, circulating to deliver oxygen and essential nutrients to every corner of the body. Simultaneously, it flushes out metabolic waste through sweat, urine, and stool. It is estimated that an average adult expels about 2.3 liters of water per day.
To maintain a healthy balance, we must replenish the fluid we lose. While food provides some hydration, drinking pure water remains the most effective method. However, consuming over 2 liters of water daily can feel like a challenge. To help you achieve this, let’s explore the "Ideal Hydration Cycle" for your daily routine.
