According to a survey conducted by Kao, the percentage of people who answered 'I always dry my clothes indoors' for 'indoor drying on days other than rainy days' increased from 12.9% in 2006 to 33.3% in 2025*2. This result suggests that the lifestyle of regularly drying clothes indoors regardless of the weather is spreading.

On the other hand, in a survey regarding clothing odors, 51.7% of all respondents answered that they 'sometimes worry about odors', which is about half. Among them, while 44.2% of those who do not dry clothes indoors were concerned, the figure was higher at 54.7% for those who do*3. This indicates that consumers who practice indoor drying tend to have a higher awareness of and concern about clothing odors.

Furthermore, the most frequently mentioned type of odor was 'musty odor'*4. It is presumed that indoor drying is an environment where musty odors are more likely to occur because it is more humid and clothes take longer to dry compared to outdoor drying or using a clothes dryer.

Therefore, we are now launching 'Wide Haiter PRO Liquid Heyaboshi' from the 'Wide Haiter PRO' series, specializing in musty odors. It thoroughly cleans the food source for bacteria, which is one of the causes of musty odors. Furthermore, its antibacterial effect inhibits the growth of bacteria*5. In addition, a new 'Musty Odor Specialization Formula' has been adopted. With 6 times*1 the musty smell deodorizing ingredients, it thoroughly eliminates even stubborn musty odors. Just by 'adding a little' to your usual laundry, you can remove musty odors that cannot be removed with detergent alone, finishing with a clean and refreshing scent.

The 'Wide Haiter PRO' series is an oxygen-based bleach that addresses deeper laundry concerns. It is specifically designed to tackle stubborn stains and odors, and its feature is the powerful removal of troublesome dirt and odors that cannot be completely removed with detergent alone. Since it is not chlorine-based, it can be used safely on colored and patterned items.

With the addition of this new indoor-drying type, the series now has a total of 4 items.
