Hot Album Carbonated Spring Tablet Co., Ltd. (Headquarters: Hachioji City, Tokyo; Representative Director and President: Shigeharu Koboshi), the originator of bicarbonate development holding manufacturing patents for pure bicarbonate bath additives and an industry pioneer providing OEM services to many manufacturers, was certified as a 'ME-BYO BRAND' by Kanagawa Prefecture on March 27, 2026.
The bathing habit of 'washing the body vigorously with soap and shampoo foam' has been established since Japan's post-war high economic growth period. However, in modern times, it has been pointed out that excessive washing may affect the skin barrier and contribute to 'pre-disease (ME-BYO)' states such as coldness, fatigue, and lack of sleep caused by busy daily lives.
This is a bathing style utilizing bicarbonate ions that presents a new option for such bathing habits.
The initiative of the Bicarbonate Warm Bathing Method (Human 'Spring' Washing Machine (Home Hot Spring)), which proposes simple care centered on soaking in hot water and supports healthy body building, has been recognized. The company is also working on 'visualization of pre-disease improvement' using wearable devices, and an award ceremony will be held at the Kanagawa Prefectural Government Office on Wednesday, April 8, 2026, with Governor Yuji Kuroiwa in attendance.
■ Background of Kanagawa Prefecture 'ME-BYO BRAND' Certification
Reviewing daily lifestyle habits is considered important for improving 'pre-disease (ME-BYO).'
HOT TAB has redefined the bath from a mere place for washing to a place for relaxation and conditioning utilizing the action of bicarbonate ions.
■ Three Features of This Product
① A simple bathing style centered on 'soaking' care
Designed with unique manufacturing technology that allows neutral bicarbonate ions to remain in the hot water for a long time. This gently aids in washing away sebum and dirt during bathing and supports a bathing habit that suppresses friction on the skin.
② Supporting blood circulation promotion through warm bathing
Promotes blood circulation through the warm bathing effect by soaking leisurely in lukewarm water of about 36–41°C. It supports maintaining body temperature after bathing and contributes to the reduction of coldness and fatigue.
③ 'Visualization of pre-disease' through digital technology
Uses wearable devices to verify the impact of bicarbonate bathing on quality of life. It visualizes changes in relaxation state (autonomic nerve balance) and sleep state as data, supporting motivation for continuous self-care.

■ Bicarbonate Warm Bathing Method by HOT TAB and Scientific Evidence
The 'Bicarbonate Warm Bathing Method' using HOT TAB is an approach that promotes blood circulation through micro-bicarbonate ions dissolved in hot water by soaking in lukewarm water of 36–41°C for about 15 to 30 minutes.
It has been reported that this action relaxes blood vessels, increases peripheral blood flow by 4 to 5 times after 15 to 20 minutes, and raises body temperature by 0.5 to 1°C. Raising body temperature increases metabolism and immune activity, suggesting the possibility of improvement not only in coldness and sleep troubles but also in mental aspects such as stress.
Approach based on scientific evidence
The usefulness of the Bicarbonate Warm Bathing Method has been published in the British medical journal 'Scientific Reports' (2021/2024), suggesting its effectiveness in promoting blood circulation, supporting immune function, improving sleep quality, and alleviating stress.
In addition, bathing using naturally derived materials such as baking soda and citric acid is characterized by being gentle on the skin for a wide range of generations, from babies to the elderly. Furthermore, it is expected to be used as a substitute for chemical soap and synthetic shampoo, supporting relaxation time while gently washing away dirt from skin, hair, and pores.
■ Health is surely found in nature bathing.
'The further a person moves away from nature, the closer they get to sickness.' These are the words of Hippocrates, the saint of medicine in Greece 2,500 years ago. The teaching is that when various synthetic chemical substances not found in nature or chlorine remaining in tap water are absorbed through the skin, humans feel chemical stress unconsciously, and the sympathetic nerves are constantly tense, lowering blood flow, which eventually makes them more prone to illness.
■ 'Soak for 30 minutes, and you will love your tomorrow'
Three HOT TAB tablets in lukewarm water. Once they have completely dissolved, just soak leisurely for 30 minutes.
We want that time to become a 'habit for creating energy for tomorrow' that is indispensable in a busy life—this is the core message of HOT TAB.
At the end of the day or as a weekend reward, surrender your body to the hot water and take a deep breath. 30 minutes of natural conditioning without relying on stimulation should make you love yourself tomorrow.
