The frequency of occurrence of each word was as follows: nouns: people (n=28), government (n=15), isolation (n=10), measure (n=10), and number (n=9); verbs: infect (N=8), need (n=7), isolate (n=6), want (n=6), and increase (n=5); and adjectives: Japanese(n=7) , strong (n=5), close (n=5), timely (n=3), slow (n=3), whole (n=3), and many (n=3). (Table6)
Health-Seeking Behavior upon experiencing symptoms of COVID-19
We asked the respondents about what you will do when the COVID-19’s symptom appears, 52.5% of the Call consultation center, 29.5% stayed home, 8.6% did not know what to do, and 6.6% visited health facilities immediately. (Table7)

We asked respondents about the difficulties in visiting Japanese health institutes. 82.7% respondents feel difficulties in visiting Japanese health institutes. The existence of anxiety regarding the cost of health institutes was 46.9%, also more likely present in those aged 20-29 (P=0.00), students including technical interns (P=0.00), and shorter length of stay are more likely in Japan (P=0.00) . Language problems in health facilities were 60.2% also more likely, students including technical interns (P=0.00), and those with a shorter length of stay (P=0.00). (Table8)
Regarding the correlates of Anxiety of cost in visiting health facility in Japan, multiple logistic regression analysis showed VISA status of students/Technical intern was the strongest predictor of having Anxiety of cost (AOR = 3.23), followed by Length of stay of less than 3years (AOR=3.14) with statistically significance (P=0.00, 0.01). Also, the correlates of Language problem in visiting health facility in Japan, multiple logistic regression analysis showed Length of stay of less than 3years was the strongest predictor those who have language problem in visiting health facilities (AOR= 3.14 P=0.01) (Table 9).
