Oshi Marks and Fan Names: How Emoji and Fandom Names Build Community in Japan

Lots of people had the same emoji next to their names, and you wondered whose fans they were. Here is what oshi marks and fan names mean and where they come from, how to find the official mark, and what to watch for when you use one.

What an Oshi Mark Means

Oshi mark (推しマーク) is the emoji that symbolizes your oshi. VTubers, livers (live-streamers) and idols often set their own symbol emoji, and fans add that mark to their social media name field, profile and cheering comments to show where they belong.

“That’s someone with the 🌙 mark. Maybe a fellow fan (doutan).” Within a kaiwai (fandom sphere), the mark works as a silent business card.

• Fan nameThe name of the fan group
• Fandom nameThe official community name
• Oshi colorA color you wear

Marks work in text, colors work on what you wear.

Telling It Apart From Similar Terms

An oshi mark is a combination of emoji that shows a creator, a fan name is a name for the group of fans, and a fandom name is the officially set name of the community. On a profile, keep the role of each distinct.

Both express “where I belong,” but a mark works within text and a color works on what you wear. That’s why many people use both: an emoji in the name field, a color at the event.

Works in text

Oshi mark

• Name fields, comments, hashtags
• Anyone can add it at any time

Works on you

Oshi color

• Penlights, clothes, merch
• Seen at events

Many fans use both.

Examples

• “I added my oshi mark after my name.”
• “When they call us by our fan name, it feels like my support is getting through.”
• “I voted in the campaign to name the new streamer’s fans.”
• “The marks in my name field keep piling up. It’s the fate of a hako-oshi (a fan of the whole group).”
• “I searched the mark and fellow fans came up one after another. I can’t stop following.”

What a Fan Name Means

Fan name (ファンネーム) is the official name for a group of fans. Often the oshi or the management coins it, and being addressed by a distinct name rather than a generic “fans” is the core of the fans’ sense of unity.

It owes a lot to K-pop’s fandom-name culture (each group has an official fan club name), and among VTubers and streamers it has become firmly established as the “listener name.”

Where It Comes From: From K-Pop to Streaming Culture

It was K-pop that grew the culture of naming a group of fans. Many groups have an official fandom name and/or official color, and a named fandom acts as the subject of support. This style became the global standard for fan culture.

In Japan, that idea met streaming culture and evolved into its own form. It has become nearly a convention that VTubers and livers set an oshi mark (emoji) and a listener name as a pair at debut. The emoji serves as a marker for searching and interacting in place of a hashtag, and the listener name is used when addressing fans during streams. The two-piece set of mark and name prepares an entrance to the fandom from the very beginning.

2. 02Meets streamingIn Japan, the idea evolves
3. 03Set at debutOshi mark plus listener name
4. 04Ready-made entranceThe fandom has a door from day one

The emoji works like a hashtag and the listener name is used when the streamer addresses fans.

In Practice: Finding and Using a Mark

1. Check official information — The mark is often stated on the person’s social media profile, official site or stream description box
2. Add it to your name field or profile — No permission or qualification is needed. You can add it any time as a declaration that “I’m supporting them from today”
3. Multiple marks are fine — If you have several oshi, line them up. Taking one off is also up to you, and some people quietly remove a mark to signal they’ve moved on

Putting on a mark is the easiest first step into a fandom for a new fan. You can join the circle with a single emoji, before buying any merch or attending any event. Plenty of people name it as the first move of their oshi-katsu debut.

Marks also work as a search tool. Used together with the official hashtag, they help reactions gather, and for people who keep a separate otaku account, they act as a signboard that shows the character of the account at a glance.

Naming Is What Builds a Fandom

What oshi marks and fan names have in common is that naming gives shape to “being a fan.”

1. Making belonging visible — A single mark helps you find fellow fans
2. Inventing a way to address people — “Everyone in [fan name]” reaches the heart far more than just “everyone”
3. An entrance to the culture — For a new fan, “putting on the mark” is the first step of joining the fandom

Naming gives shape to being a fan.

Common Misunderstandings

• Using a mark does not make you an officially recognized fan — It’s a culture anyone can join freely
• A fan name doesn’t mean you’re a fan club member — You’re called by the fan name even if you aren’t a member
• Some oshi have no mark — In that case, a mark that arose naturally among fans is sometimes used. Loosely following the customs of the sphere is enough
• Emoji look different depending on the environment — The same code can look different on different devices and apps, so when you put one on printed material or merch, you need to check the real thing

Notes From The Oshi Lab: The Smallest and Strongest Device for Taking Part

A fan name is the smallest and strongest device in community design. A group that has been given a name unites and acts more than a nameless audience, and this is a principle of brand communities in general, not just fandoms. What matters is the timing of the naming and whether people feel convinced by it. Fan names with a story of “not being forced on anyone,” such as fan submissions or the person’s own idea, are loved most deeply.

The implications on the oshi mark side shouldn’t be missed either. The emoji is the smallest device for participation that anyone can use right now, bringing the cost of entering the fandom close to zero. Applied to community management, this means preparing a light form of participation at the level of “putting on the mark,” ahead of “paying dues” or “coming to an event.” The more you lower the hurdle to declaring belonging, the wider the base of the community becomes.

One more point from the operational side. Marks and names are assets that are costly to change later. When more creators in the same sphere use similar marks, they stop working as search markers, and if the pronunciation of a fan name isn’t settled, calls to fans don’t line up. What matters more than the moment of deciding is how many years it can keep being used afterward, and that time axis may be what the people doing the naming should look at first.
