■What is Sumikkogurashi?
Created in 2012 with the keyword "This is where I feel at ease," the Sumikko characters are not just cute, but also have a slightly negative and surreal charm that has garnered popularity from a wide range of people. When riding a train, the corner seats are always the first to be taken, and when going to a cafe, people want to secure a corner seat if possible… The Sumikko characters embody this feeling that many Japanese people share.
