The Chrome extension has been discontinued
The Kaomojis.jp public API (/api/v1) and our embed features (oEmbed and the embed widget) were discontinued on October 9, 2026.
This Chrome extension ran on the public API, so it has been discontinued as well.
As part of our security measures, we decided to close the entry points that could be called directly from outside the site. Thank you to everyone who used them.
You can still search for kaomojis and copy them on the site, just as before.
