Mandom Corporation conducted an "Awareness Survey on Sweat and Odor" targeting 1,000 men and women in their 10s to 50s to help alleviate consumer concerns related to sweat.
The survey results revealed that recent abnormal weather and unseasonable heat have led people to feel that "summer starts earlier and lasts longer." With the severe heat, more people are experiencing discomfort from sweat and developing a dislike for summer, suggesting that sweat care is now a "life infrastructure" necessary for living comfortably.
Survey Result Summary
1. The highest number of people feel summer starts in "May" and ends in "October." The perception that "summer = half a year," extending into the calendar autumn, is spreading.
2. Over 40% feel that sweat volume and discomfort have "increased" in recent years. More than half of the total respondents answered that they have "come to dislike summer."
3. Over 60% spend money on sweat countermeasures. A segment spending over 3,000 yen per summer has emerged, showing that paying for sweat care is becoming generalized.
4. Over 30% use sweat care items daily. About 1 in 5 are heavy users who consume "3 or more body sheets a day."
5. The top usage scenes for sweat care items are everyday situations like "after commuting/going to school" and "prevention while getting ready."

[Perceived Summer is Now "Half a Year"]
1. Most answer summer starts in "May" and ends in "October." Half the year is now summer.
When asked about the perceived duration of summer in Japan over the past few years (1-2 years), the most common answer was that summer begins in "May" and ends in "October." Regarding the onset of summer, the percentage remains below 10% until April, but once May begins, about 60% (57.9%) truly feel that "summer has started." On the other hand, the most common time to feel the end of summer is late October (28.9%), followed by early October (25.9%). Over half the people only feel the end of summer once October begins. Because the heat continues into what is calendar-wise considered autumn, the traditional concept that "summer means July and August" has changed, and a new seasonal sense that "half the year (May to October) is summer" is taking root in modern Japan.
2. Over 40% answer that "sweat volume and discomfort have increased" in recent years. "Sweat stress" rises due to extreme heat.
When asked about changes in sweat volume and discomfort in recent years, over 40% (43.9%) of the total responded that it has "increased," highlighting the spread of sweat-related troubles. In particular, over 50% of men and women in their 10s, women in their 30s, and men in their 40s actually feel this "increase." Against the backdrop of severe heat caused by an "earlier and longer summer," the reality is that sweat-related issues are spreading across all generations and genders.
Many shared how sweat disrupts their daily lives, with comments like "I got sweat marks from my backpack and felt embarrassed every time I took it off" and "Just walking outside makes me sweat immediately, making me dread going out."
3. Due to extreme heat, over half answer they "dislike summer now." A shift from a "summer to enjoy" to a "summer to endure."
When asked about the change in their impression of summer in recent years, those who answered "I dislike it more than before" accounted for over half (53.6%) of the total, vastly outnumbering those who "came to like it" (10.9%). A tendency to shy away from summer is seen across a wide range of ages and genders, but it was most prominent among women in their 10s, reaching nearly 70% (67.0%). Even though summer is a season with many fun events like festivals and fireworks, the reality is that due to recent severe heat, it has turned into a "season to endure" for a wide range of generations.
[Sweat Care is Now "Life Infrastructure"]
4. An era where about 60% pay for sweat countermeasures. A segment spending over 3,000 yen has also emerged.
When asked about the amount of money spent on summer sweat countermeasures (purchasing items, dry cleaning, etc.), it became clear that over 60% (63.7%) are spending money on it. Looking at expenditures, a segment spending over 3,000 yen in one summer accounts for 14.0%, and a heavy user segment (2.9%) spending over 10,000 yen is also visible. Against the backdrop of prolonged extreme heat, people's high awareness of sweat care is evident. The reality that sweat care has transformed into an indispensable "life infrastructure" for daily life was highlighted.
5. Over 30% answer they use sweat care items daily. Some heavy users use them "twice or more a day."
When asked about the frequency of using sweat care items, 34.7% answered they use them "every day," and within that, 17.2% use them multiple times, "twice or more a day." The reality that frequent sweat care is becoming an essential daily routine for modern people was highlighted.
