In South Korea, about 20 cities belong to Cittaslow, and they use their status in publicity campaigns. In Japan, however, only a few cities besides the two current members are considering joining. Officials from Maebashi and Kesennuma, which joined Cittaslow in 2017 and 2013, respectively, will form a nationwide organization together with experts and release information on a website and through social media to support other local bodies' bids for membership. If at least three local bodies within a single country belong to Cittaslow, they can receive organizational certification, which is said to increase their ability to disseminate information. Maebashi Mayor Ryu Yamamoto commented, "Rather than just attracting more tourists, I'd like to see more municipalities that allow people to appreciate their towns at a slow pace and lead happy lives." Kesennuma Mayor Shigeru Sugawara said, "This is such a valuable movement as it can lead to sustainable development goals. We would like to expand this to the whole of Japan."
