Moreover, with consumers heading towards a healthier lifestyle, it has always been easier to purchase water purifiers, which can remove impurities but keep the mineral content. Furthermore, new smart technologies, for example, Internet of Things (IoT) ready purifiers, have also increased consumer convenience and system effectiveness, with additional problems solved, like neglected filter replacement notifications and monitoring the real-time performance of purified water. Overall, these technological developments are transitioning water purifiers from standard devices to sophisticated, essential components of Japanese lifestyles.

Restraining Factors

The first major challenge that restrain the market growth is the high initial cost. Some purification systems, such as reverse osmosis (RO) systems or multi-stage filtration systems, are sophisticated purification systems that can seem expensive to price-oriented customers. A second challenge facing the Japanese water purifier industry is the presence of counterfeit products. As confirmed, market demand for water purification devices is growing, and low-quality and unverified purifiers have entered the market and undermined consumer confidence. These products mostly fail to meet performance and safety criteria, exposing consumers to drinking contaminated water. Health threats may arise from incorrect filtering or ineffective purifying practices from counterfeit products, potentially impacting the industry's reputation as a whole. In addition, customers may face even more complex choices if unable to differentiate between genuine, quality purifiers and sub-standard imitations.
