[Purpose] This study aimed to examine and compare the prevalence of frailty in 75 year-old people sampled in two remote years, namely 2006 and 2019. [Participants and Methods] A total of 910 participants aged 75 years were included (502 people in 2006 and 408 people in 2019). We compared the total score of the Kihon checklist and each question for males and females between the two years. [Results] The prevalence of frailty decreased from 24.3% in 2006 to 15.2% in 2019. The comparison of the 2006 and 2019 Kihon checklists revealed significant differences in activities of daily living, physical function, oral function, outdoor activities, and cognitive function. [Conclusion] Frailty among 75 year-old individuals improved in 2019 compared to that in 2006. Improved activities of daily living, physical function, outdoor activities, and cognitive function were major causes of improved frailty in 2019.
