HOT TAB, certified as a Kanagawa Prefecture "ME-BYO BRAND," launches a joint spring self-care campaign with Dr. Air.

Hot Tab Carbonated Spring Tablet Co., Ltd.'s "HOT TAB," a brand certified as a Kanagawa Prefecture "ME-BYO BRAND," will launch a joint campaign with Dream Factory Co., Ltd.'s total body care brand "Dr. Air," focusing on spring self-care habits. Spring is considered a time when people are prone to feeling changes in their physical condition due to seasonal shifts, such as autonomic nervous system imbalances and poor circulation. This project proposes self-care habits that are easy to incorporate during such times. This initiative is a joint project centered on sales promotions and SNS campaigns.

Background of the Joint Project: Offering the "warming" option of bicarbonate for spring's "fluctuations."

Spring is a season when the autonomic nervous system is easily disrupted due to temperature differences and environmental changes, making it easy to lose physical and mental balance. "HOT TAB," the inventor of bicarbonate bath additives, uses its unique patented manufacturing technology to efficiently dissolve bicarbonate ions by keeping the bath water neutral, thereby achieving a high warming bath effect.

In this campaign, we will widely propose a "circulation care habit" that combines "daytime conditioning" through Dr. Air's body care with "nighttime warming" through HOT TAB, promoting blood circulation and deep relaxation.

Spring Circulation Care Campaign

In this campaign, we propose a spring self-care habit of "conditioning during the day and warming at night," combining the bathing habit of HOT TAB's bicarbonate bath with the body care habits proposed by Dr. Air.

Furthermore, in the "Awareness Survey on Spring Fluctuations" conducted prior to the campaign launch, approximately 70% of respondents reported feeling changes in their physical and mental condition in spring, once again highlighting the importance of self-care during seasonal transitions.

Survey Results: Over 80% experience "spring ailments," with "easy continuation" being sought.

In a survey conducted by Dr. Air in March 2026 targeting 972 members of its official online store, 84% responded that they "feel changes in their physical condition during seasonal transitions." Furthermore, the top priorities for continuing self-care at home were "being easy to do (75.1%)," "being easy to continue daily (73.1%)," and "not taking much time (47.2%)." Additionally, 83.8% found "self-care habits combining body care and bath time" appealing, indicating an interest in habits that can be effortlessly incorporated into daily routines.
