In Japan, the popularity of sea bathing is rapidly declining. In response to this situation, articles such as "Young people's " lack of interest in the sea "revealed; 40% of teens and 20-somethings don't feel 'close to the sea'", "The In this study, we examined the relationship between the number of beachgoers and the number of beaches closed. This study aims to understand the "causes" of " lack of interest in the sea " and to clarify the factors that lead to the decline in popularity of sea bathing. The method to grasp people's awareness was a questionnaire survey using questions, but in this paper, we focused on the "comments" on the articles to understand the factors. In this paper, we used the comments on the article "Why Japanese people are " lack of interest in the sea " published in YOMIURI ONLINE on July 7, 2018, and analyzed them using morphological analysis according to the flow shown in Figure 1. The target of the analysis were the comments that were positive and had direct or indirect factors against the " lack of interest in the sea " shown in Table-1. The frequency of occurrence of "sea" was the highest, followed by "dirty," "don't go," and "dangerous," which were considered as factors for " lack of interest in the sea ". The number of parts of speech related to sea bathing is relatively small in the group of less than 100 occurrences, accounting for about 14% of the total. On the other hand, the frequency of parts of speech that are not directly related to bathing in the sea appears in many senses. On the other hand, the frequency of parts of speech that are not directly related to bathing appears to be high, and annoying behaviors such as "picking up girls" and "taking pictures" are pointed out. In the case of "dirty," which appeared frequently, major factors such as sandy beaches and toilets at beaches and complementary facilities were evaluated as "dirty". "Tattoos" and "Yankee" were also pointed out, and dislike for the atmosphere of beaches was pointed out. Figure 2 shows the co-occurrence network of the parts of speech that affirm the " lack of interest in the sea ". The size of the circles in the figure indicates the frequency of occurrence of the part of speech, and the lines connecting the circles indicate the connection between the words. The size of the circles in the figure indicates the frequency of the part of speech, and the line connecting the circles indicates the word association. The position and distance of the circles are not related to the word association. This co-occurrence network diagram is divided into seven groups. The group centered on "sea" shows co-occurrence relations such as "dirty" for "sea", "don't go" for "sea bathing", and "people", "many", and "group". For "swimming pool," the respondents said they would go instead of the sea. In the case of "swimming pool" are considered to replace the sea. In addition, there is a co-occurrence relationship between "now" and "old days" and "blemish", "skin", and "ultraviolet rays"." Prohibited" is associated with "Creatures" and "music" "picking up girls" is associated with "purpose" "taking peeping films" and "swimsuit" "dangerous" is associated with "creatures" and "beach house" is associated with high prices and traffic jams related to toilets, showers, and parking lots. In addition, "sand" co-occurs with "hassle" "dislike" and "gooey" and "beach house" "dirty" and "bad" co-occur with other parts of speech in addition to group composition. In the past, swimming was not seen as a special event during the summer season, but rather as a normal leisure activity that required a lot of preparation. However, the interest in swimming has not disappeared, and the tendency to use swimming pools for convenience and comfort has emerged. This does not mean that people are " lack of interest in the sea " = denial of swimming in the sea , but rather that it is becoming increasingly important to reconsider the use of beaches in a flexible manner in accordance with changes in the way people enjoy summer leisure activities.
