"Koko Note" is an emotion-recording SNS where you can express your true feelings anonymously. Whether it's complaints or vague unease, simply write them down briefly, categorized into six emotions: joy, surprise, sorrow, anger, happiness, and shame. There are no replies or photo attachments. It's not a place to show others—it's simply a space where you externalize your emotions into words, and that's enough.

On the timeline, you'll also see records of someone else in Japan whose emotions were stirred in the same way, right now. Without knowing their name or face, there's only the fact that "someone's heart was genuinely moved today." However, you can pre-filter out emotions you don't want to see, so you can choose to view only the feelings you're able to accept.

Registration takes just 30 seconds—only a nickname and password required. Posts automatically disappear after 90 days, so there's no anxiety about leaving your true feelings behind. As you continue using it, you may encounter unexpected titles and discover small insights about yourself.

Simply put into words the feelings you can't tell anyone. Before you know it, you've become one record of someone's emotions being stirred somewhere in Japan. "Koko Note" is that kind of place.
