This study collected and analyzed various linguistic landscape signals built by local residents to maintain the quality of their life styles from disadvantages of over-tourism caused by rapid increase of foreign tourists. Results of analyzing the linguistic landscape signals of Tsushima, Yufu, and Fukuoka are as follows.
Firstly, the types of issues concerning the over-tourism are Trash disposal issue, Manners for using toilets, No take-out food, No smoking, No photographs, No entry, No parking, CCTV in operation, No damage to cultural properties, Manners for using facilities, No noise, and No shoplifting, etc. Secondly, in case of Tsushima, the trash disposal issue was most serious. It appears that most linguistic landscapes signals in Tsushima included signals written in Korean. Suggested by this fact, it seemed that the majority of tourists in Tsushima was Korean. On the other hand, in Yufu and Fukuoka, most frequent linguistic landscape signal types were No smoking, No take-out food, and Manners of using toilets. Thirdly, in Japanese expressions used in the over-tourism linguistic landscape signals, many forms of prohibition, command, and punishment were found. The translated Korean expressions were often rough translation of the Japanese expressions. Some translated Korean linguistic landscapes signals contained many expressions that raised a doubt or an embarrassment about sender's intent from the perspective of Korean tourists. Fourthly, in the general over-tourism, the linguistic landscapes signals exhibit messages of direct and strong caution, prohibition, and warning, which may offend tourists. Therefore, the current study offered the necessity of linguistic landscape signals written in grateful form, apology form, and euphemistic prohibition expression, etc. in consideration of tourists who are message recipients
