Meaning
The kanji 祝 inside a circle, meaning celebrate or congratulations in Japanese. It is the character seen on festive banners and gift envelopes in Japan.
It works for birthdays, weddings, graduations, promotions and any good news: “㊗️ Congrats on the new baby!” It adds an East Asian festive touch, much like 🎊 or 🎉. Readers of Chinese characters will recognise it from the word for wishing someone well.
