Pixie Dust Technologies, Inc. (Headquarters: Chuo-ku, Tokyo; Chairman: Yoichi Ochiai; President: Taiichiro Murakami; hereinafter 'PxDT') conducted a survey on brain health among 1,000 50-year-old men and women nationwide, as Japan enters a turning point where its median age exceeds 50.
With the arrival of the 100-year-life era and the era of working until 70, coupled with the evolution of technologies such as AI, the environment surrounding 50-year-olds is changing dramatically. In an era where people are expected to live and work healthily for a long time, 'brain health,' including concentration and memory, is becoming an increasingly important theme.
Therefore, our company focused on 50-year-olds, who can be considered the core generation of Japan, and conducted a survey on their awareness and anxiety regarding brain health, as well as their daily health habits.
The results revealed that while approximately half feel a decline in memory, only 3.0% are consciously practicing measures for 'brain health' such as concentration and memory. Furthermore, the most common reason for finding brain health measures difficult was 'not knowing what to do,' highlighting a significant gap between awareness and action regarding brain health.
This release explores the challenges and background revealed by the actual situation of brain health among the 50-year-old generation.

According to Worldometer, based on the UN World Population Prospects 2024, Japan's median age is estimated to be 50.2 years in 2026, marking an era where the center of the population exceeds 50 years old.
[Survey Summary]
① Over 70% of 50-year-olds feel they have entered a 'turning point in life.' While opinions on the future are divided between optimism and pessimism, the overall result leans slightly towards pessimism.
② The themes that bring the most enjoyment in the future are tied between 'hobbies' and 'travel.' The theme causing the most anxiety is 'maintaining health.'
③ Over 85% of 50-year-olds actually feel a 'decline.' The top 3 specific declines felt are 'physical strength,' 'muscle strength,' and 'memory.'
④ About half of 50-year-olds are engaged in health measures. Among these, the area least addressed is 'maintaining brain health,' such as concentration and memory. The biggest reason for not practicing is 'not knowing what to do.'
⑤ Regarding future 'ability to work,' there is anxiety about 'maintaining brain health.' While 1 in 3 50-year-olds anticipates working beyond age 70, over 60% answered that they are not confident in continuously learning new knowledge and skills like AI. Anxiety about maintaining brain health ranks high among concerns about continuing to work.

① Over 70% of 50-year-olds feel they have entered a 'turning point in life'! Opinions on the future are divided between optimism and pessimism, but overall results lean slightly towards pessimism.
When asked if they felt they had entered a 'turning point in life' upon turning 50, a combined 75.3% answered 'strongly feel' (32.9%) and 'somewhat feel' (42.4%), indicating that a majority feel they have reached a milestone in life.
Furthermore, when asked how they view their future lives, the pessimistic group, combining 'somewhat pessimistic' (36.0%) and 'very pessimistic' (18.1%), accounted for 54.1%, surpassing the optimistic group, combining 'very optimistic' (5.0%) and 'somewhat optimistic' (40.9%), at 45.8%.
These results suggest that while 50 is a major turning point for many, they have mixed feelings of expectation and anxiety about the future.
4 Comments from Optimistic 50-Year-Olds:
- Because my children are independent, I feel I have fulfilled my responsibilities to some extent.
- Child-rearing is coming to an end, so I will have more time for myself.
- I have found new hobbies and am able to do what I want.
- My children have left home, and I look forward to a new life with my spouse.
4 Comments from Pessimistic 50-Year-Olds:
- I have an invisible anxiety about how long I can stay healthy and work, and what to do with my life after retirement.
- My body and mind don't do what I want.
- I haven't saved enough for retirement, and with rising prices, I'm anxious about both finances and future health. I'm also caring for my parents, which is a heavy burden.
- I have no children, so I am prepared to die alone.
② The themes that bring the most enjoyment in the future are tied between 'hobbies' and 'travel.' The theme causing the most anxiety is 'maintaining health.'
When asked about themes they look forward to in the future, 'hobbies' ranked highest at 46.0%, followed by 'travel' at 45.9%.
On the other hand, when asked to select all themes they feel anxious about in the future, 'maintaining health' was the most common at 58.1%, significantly surpassing the percentages for 'hobbies' and 'travel,' which were cited as sources of enjoyment.
This suggests that while 50-year-olds have positive expectations for the future, such as hobbies and travel, they feel stronger anxiety about 'maintaining health,' which is the foundation for continuing to enjoy these activities.
③ Over 85% of 50-year-olds feel a 'decline'! The top 3 specific declines felt are 'physical strength,' 'muscle strength,' and 'memory.'
When asked if they feel a decline compared to their 30s and 40s, a combined 85.8% answered 'strongly feel' (39.1%) and 'somewhat feel' (46.7%), revealing that the vast majority feel some kind of decline.
Furthermore, when those who feel a decline were asked how they feel about this change, a combined 88.7% answered 'strongly anxious' (27.3%) and 'somewhat anxious' (61.3%), indicating that most are worried.
When asked about specific abilities they feel are declining, the top results were 1st: 'physical strength' (76.5%), 2nd: 'muscle strength' (50.1%), and 3rd: 'memory' (49.4%). In addition to items related to physical decline, 'memory' ranked high, indicating that items related to declining brain function also account for a high proportion.
