In conducting an exploratory data analysis to study the hit mechanisms of manga and anime works with appealing supporting characters, the author began by assessing the volume and content of Twitter posts on Demon Slayer and observed that SNS not only facilitated communication between devoted fans, but also served to fulfill the desire to own merchandise and to provide a place for publication of derivative works.　Furthermore, in an analysis using the Character Quantitative Survey unaided recall data, the top unaided recall works were classified into four types based on supporting character popularity patterns. The results obtained by creating a composite variable of unaided recall weighted by simple total based on the number of recall of the work's name or character and assessing the mean values and correlations of each variable measured for each work showed that the composite variable of unaided recall had a strong correlation with the indices of tie-in merchandise purchase and purchase intention, and with the indices of 'high spirit and fun' and 'attention and impersonation' in the field of offered experience.

Part of the contents were reported at the 49th Consumer Behavior Research Conference of the Japanese Association for Consumer Behavior Research in November 2014. In order to confirm the potential of local mascot characters as communication tools, which were in the midst of a boom at the time of the presentation but whose findings had not yet been systematized, we first clarified their definition and classification, then measured the level of favorability of local mascot characters nationally and by local prefecture, and explored the factors behind their support.
The results revealed that local mascot character fans exist in a wide range of age groups, with seniors aged 60 and above exceeding fans of characters in general, but that only a few characters are nationally popular, and many local mascot characters have penetrated only locally or are still unknown even in their hometowns. It was confirmed that local mascot characters with high national favorability were unaffected by factors such as origin (official or not), prototype (human, animal, or other), and presence or absence of local specialty motifs, while those with high local favorability were mostly official local government characters or characters with local specialty motifs.

It confirms trends in the domestic character market and consumer attitudes toward characters, and organizes quantitative survey results and case studies of the use of characters in advertising, PR, and other corporate communications as a marketing communication strategy.

Using the "TV CM KARTE" data, the differences in recognition efficiency, favorability, and product purchase intention by type of performer were verified. Based on a research report at the 30th National Convention of the Japan Advertising Association in October 1999.
The results also demonstrated the effectiveness of using popular celebrities and characters in converting the audience to favor the CM and the brand, especially in the low-involvement (food, shoppable items, etc.) and feel-type (confectionery, beverages, etc.) product categories where appeal through peripheral routes is considered to be effective. The use of popular TV personalities and characters was proven to be effective in converting consumers to favor CMs and brands.

Local Mascots with peaks from 2013 to 2014 in Japan experienced a decline in exposure to mass media as the boom subsided. Currently, their own SNS transmission is the starting point of information circulation with local residents and core fans. In order to derive hints of the future activities of the Local Mascots, the following analysis is conducted for the character ranked in the non-aided recall of "favorite Local Mascots" in Japan or local prefectures in the quantitative survey of the past five years went. 1) Correlation of favorability by Google search and Twitter writing, non-aided recall. 2) Pattern arrangement of Twitter write content which is easy to diffuse information. As a result, the following was clarified. Information transmission by SNS leads to maintenance of core fan indicated by non-aided recall. To spread to a wide range of people other than local residents and core fans, circulate information with mass media and SNS. Dialing by celebrities and companies and organizations is more effective than characters themselves and other characters.

In order to clarify the effects on 1) publicity to residents outside the region and 2) fostering local pride among local residents, which are generally considered as the value of utilizing "local Mascot characters" whose real events have been cancelled due to the Corona disaster, SEM was conducted using the "Character Quantitative Survey" data conducted in November 2021. SEM was conducted using data from the "Character Quantitative Survey" conducted in November 2021, with Model 3 using a composite variable in which the 1-0 response scores were added up, and Model 4 using the response scores as they were.
The results showed that local characters increase the local pride of fans in the region by providing "healing and comforting" experiences. It was also confirmed that "healing and comfort" and "participation, attention, and identification (becoming)" with the character form an attachment to the character, leading to interest in the region among fans outside the region. However, there were some results that indicated that the ardent behavior that shows attachment to and support for characters outside the region does not lead directly to local pride or even to interest in the region.

Experiences provided by local mascot characters are less frequent than those of existing characters in general, and this tendency is more pronounced outside of the local prefecture. The effects of using local mascot characters, such as changes in fan awareness and local revitalization, are generally lower outside the local area, and the differences between local and non-local areas in the "local interest" and "local visit/residence" factors, which indicate content tourism, are significant only for some popular characters.
