A bashful smile with a hand scratching the back of the head. The eyes ^^ are smiling closed-eye crescents, and the katakana ゞ on the right is doing kaomoji duty as a hand raised to scratch at hair — a universally recognized gesture for embarrassed politeness.
This is one of the oldest and most beloved kaomoji in Japanese chat. It first appeared in the early text-message era and has been in continuous use for decades. The combination of closed-eye smile and head-scratch gesture maps almost exactly to the Japanese cultural convention of てれかくし (tere-kakushi — ‘hiding embarrassment’), where someone laughs softly and scratches the back of their head when complimented or caught in a small mistake.
Use it when responding to a compliment, when admitting a small failure, or when downplaying something good you did. It works on Discord, Twitter/X, and in any chat platform that supports basic text. Because it is so culturally specific to Japanese politeness rituals, it lands especially well when you want to signal ‘I noticed, I am pleased, but I am not going to brag.’
The matching cultural concept is 謙遜 (kenson — modesty, humility). Pair this kaomoji with phrases like いやいや… (‘iya iya…’ — ‘no no, it’s nothing’), はずかしいよ (‘hazukashii yo’ — ‘I’m embarrassed’), or ほめすぎだよ〜 (‘home sugi da yo~’ — ‘you’re praising me too much’).
