Shifting Hydration Trends in Japan: The Rise of Warm Water Culture
Introduction: Japan’s Traditional Preference for Cold Water
In Japan, drinking cold water is a widespread phenomenon, especially noticeable during summers with temperatures often exceeding 30 degrees Celsius. The Japanese believe that cold water helps in cooling down and quenching thirst. This preference is also evident in restaurants, where large pitchers of ice water are commonly served, especially with hot dishes like ramen. While cold water is believed to provide relief in high temperatures, it can also lead to digestive discomfort and potentially weaken immunity.
Cultural Roots and Changing Perceptions
The Japanese affinity for cold water ties back to their cultural concept of purification. Drinking cold water is believed to cleanse ‘kegare’ (impurity or uncleanliness), particularly during the humid summers, washing away fatigue and preventing illness. Initially, offering ice water was a sign of respect due to the rarity of ice, limited to the aristocracy. Moreover, while Japan’s tap water is potable, adding ice enhances its taste, symbolizing that the water served is not just plain tap water but treated and purified.
