Japanese stream titles often begin with a label inside square brackets, such as 【歌枠】. These labels tell viewers what kind of stream to expect, and once you recognize a few of them, you can understand much of a title without knowing Japanese. This guide explains the common labels, how titles are usually put together, and some limits of the approach. The labels are conventions used by viewers and creators, not official categories, so their use varies between channels.
How a typical title is built
A common pattern is a bracketed label, then the main title, then hashtags. For example, a title might start with 【歌枠】, continue with a description of the singing session, and end with a hashtag that the channel uses for its fans. The brackets used are usually the Japanese lenticular brackets 【 】, but some creators use 「 」, ［ ］ or a slash. They all serve the same purpose of marking a category.
Titles may also include the VTuber’s name, the name of a game, a part number, a date or a short slogan. Where there are several labels, such as 【歌枠】【初見さん歓迎】, each one adds a separate piece of information. Hashtags that begin with # are often used for the stream’s chat, for posts on X and for fan art, and they are separate from the label.
Common stream-type labels
- 歌枠 (utawaku): a singing stream, in which the VTuber sings a series of songs, often taking requests from chat. Songs are usually covers, which is why song lists and timestamps are common.
- 雑談 (zatsudan): a talk or chatting stream, normally without a game, where the VTuber speaks with viewers on a range of topics.
- ゲーム実況 (gēmu jikkyō): a gameplay commentary stream. Often the title gives only the game name in brackets, for example 【Minecraft】.
- 参加型 (sankagata): a viewer-participation stream, where viewers may join the game or take part in some other way. Rules for joining are normally explained in the description.
- コラボ (korabo): a collaboration with one or more other creators. The guests are usually named in the title or description.
- 耐久 (taikyū): an endurance stream, in which the VTuber repeats a task until a goal is reached or a time limit passes.
- 朝活 (asakatsu): a morning stream, usually a short greeting and chat early in the Japanese morning.
- 晩酌 (banshaku): a relaxed stream where the VTuber has an evening drink. Some channels set age or content limits for these, so check the description.
- ASMR: streams or videos designed for relaxation, usually best with headphones.
- お絵描き (oekaki): a drawing stream, where the VTuber draws while talking.
Labels about the viewer or the occasion
- 初見 (hatsumi): literally the first time. In a game title it usually means the VTuber is playing the game for the first time, so the reactions are unscripted. In a phrase such as 初見さん歓迎 it means that first-time viewers are welcome.
- 初配信 (hatsuhaishin): a first stream. When used by a new VTuber it often refers to the debut stream.
- 告知 (kokuchi): an announcement. A stream with this label is often short and covers news.
- お知らせ (oshirase): a notice, similar to 告知.
- 記念 (kinen): a commemorative stream, such as for a subscriber milestone or an anniversary. 周年 (shūnen) refers to an anniversary.
- 誕生日 (tanjōbi): a birthday, often used for birthday streams.
- 新衣装 (shin ishō): a new outfit reveal.
- 3D: a stream using a 3D model, often with full-body movement. Concerts commonly use this label.
- メン限 (mengen): short for membership-only (メンバー限定). The stream or archive is for channel members.
- 限定公開 (gentei kōkai): a limited-release video. On YouTube, this usually refers to an unlisted video that is reached by link. The exact meaning depends on how the channel uses it, so check the video page.
Music and video labels
- 歌ってみた (utattemita): a cover song video, literally a video of someone who tried singing a song.
- オリジナル曲 (orijinaru kyoku): an original song.
- MV: a music video, which is often published as a Premiere.
- 切り抜き (kirinuki): a clip cut from a longer stream. Official clip channels and fan-made clip channels both exist. Fan clips are not made by the VTuber, so check whether the channel is official or follows the creator’s clip guidelines.
- まとめ (matome): a compilation or summary.
Titles that announce a change
Some labels relate to a major announcement, such as 【重大発表】 (an important announcement) or 【ご報告】 (a report to viewers). These can cover happy news such as a new project, but they are also used for more serious matters. The title alone does not tell you which it is, so read the description or the pinned comment. A separate guide on this site explains terms such as graduation and hiatus.
What to check beyond the title
- Look at the description, which often contains the song list, the rules of a participation stream, links to the guests or a schedule.
- Look at the pinned comment, where the creator or a moderator often posts timestamps and rules.
- Check the format of the page, since a title says nothing about whether the video is live, scheduled, a Premiere or an archive.
- Copy an unfamiliar label into a dictionary or translation tool, because creators sometimes invent their own labels.
- For anything involving money or tickets, use the official announcement and not the title alone.
Titles are written for the existing fan community, so slang and abbreviations are common, and the same word can mean slightly different things for different creators. Treat this glossary as a starting point, and if a label is unclear, look at the stream’s description or ask in the channel’s chat, where viewers are often willing to explain. As a rule of thumb, a creator’s own explanation on the stream page takes priority over any general glossary, including this one.
