Japan Trim's Survey Reveals Decline in Bottled Water Usage and Growing Interest in Home Water Generation

Insights from Japan Trim's Water Consumption Survey



Japan Trim Co., the leading manufacturer of home water purification systems in Japan, has recently conducted a survey examining the attitudes of Japanese consumers towards drinking water. With summer approaching, the survey gathered insights from 509 men and women aged 25 to 69 nationwide.

As temperatures rise, water consumption tends to increase, making August an especially relevant time to consider our hydration habits. Amidst these discussions, August 1 also marks Japan’s Water Day, established by the government in 1977, encouraging citizens to reflect on their relationship with water in daily life.

Key Findings from the Survey


1. Bottled Water Usage Decreases: The proportion of respondents indicating they consume bottled water has dropped by 4.9 percentage points from the previous year, now standing at 26.3%. Conversely, interest in purchasing electrolyzed hydrogen water ionizers has climbed by 3.6 percentage points, reaching 28.4%.
2. High Awareness of Hydrogen Water Among Young Men: Astonishingly, 84.62% of young men in their 20s reported being aware of hydrogen water and having tried it, significantly surpassing the overall average of 33.60%.
3. Growing Interest in Home Water Ionizers: With an increasing variety of options for drinking water, interest in electrolyzed hydrogen water ionizers is on the rise, suggesting consumers are more inclined to generate their own water at home.

Analysis of Survey Results


The findings reveal a notable decline in bottled water usage, indicating a shift in consumer preferences towards more sustainable and cost-effective options. The main choices for drinking water currently are tap water (30.1%), bottled water (26.3%), and purified water from filtration systems (24.0%). This trend aligns with the increased prices of bottled drinks due to rising costs of materials and logistics, pushing consumers towards more economical sources like tap and filtered water.

Additionally, the awareness and consumption of hydrogen water among young adults seem to reflect a broader trend of health consciousness among younger generations. Reports suggest that younger consumers are increasingly prioritizing health investments, which has undoubtedly contributed to the heightened interest in hydrogen water.

Rising Demand for Water Purification Systems


The survey also highlighted a growing interest in home water generation through devices like hydrogen water ionizers. The data suggests that 28.4% of respondents are considering purchasing such devices, highlighting a broader acceptance and interest in water purification technology.

In an era where choices have expanded beyond simply buying bottled water, consumers are now searching for more functional options for hydration at home. This survey indicates a critical shift in how individuals view the process of obtaining drinking water—from purchasing it to creating it within their households.

As Japan approaches the height of summer, it’s essential to recognize the importance of optimizing hydration strategies for health management. Notably, electrolyzed hydrogen water, produced by Japan Trim’s innovative devices, is recognized for its benefits in easing gastrointestinal discomfort, making it an ideal choice for summer hydration.
