In this study, the need for digital youth activities has arisen along with non-face-to-face activities in youth activity sites after Corona 19, and many youth activity programs are being converted to non-face-to-face digital. However, many youth activity facilities are still experiencing difficulties in converting to digital youth activities due to various problems. In particular, it is a time when it is necessary to think about the approach using smartphones, which accesses all these media the most, as well as the use of websites, SNS, and YouTube channels of each institution where young people get the most information. Also, the accessibility of multicultural youth and disabled youth, who are most vulnerable to these changes, was also required to be studied. Therefore, in this paper, I tried to present the parts necessary for the transition to digital youth activities in preparation for the rapidly changing diverse and egalitarian society and the post-COVID digital society. To this end, a region called Busan was selected and the current status of digital youth activities and online platforms for public youth training facilities was fully investigated.
