Japan is a super-aging society and is making efforts to extend the healthy life expectancy of the elderly. In order to prevent under nutrition, frailty syndrome, and sarcopenia in the elderly, it is necessary to maintain the functions of mastication and swallowing. A Questionnaire survey on swallowing was conducted at the annual resident health checkup in Yakumo-cho, Hokkaido, Japan, where population migration is small. 159 males and 257 females answered 15 questions about swallowing function in a self-administered manner. Participants are independent Yakumo-cho residents over 40 years old. More than 70% of both males and females answered that there was no problem with all the questions. However, compared to females, males had poorer saliva output, and had difficulty breathing due to saliva, were statistically significantly. Also, compared to males, females had a throat problem was statistically significantly. In the future, it will be necessary to investigate lifestyle habits including eating habits and exercise habits to understand the swallowing function status.
