Translation guide
The English term 'microblog' is commonly used as-is in Japanese. For the action of posting on a microblog, use 投稿する (tōkō suru) or the loanword ポストする (posuto suru). The platform itself is often called ミニブログ (miniburogu) or simply SNS.
Referring to a microblogging platform like Twitter/X, Weibo, etc.
The most direct translation, though less common than using the specific service name.
彼はミニブログで有名になった。
He became famous on a microblog.
Japanese speakers usually refer to the specific platform by name rather than the generic term.
ツイッターで見たよ。
I saw it on Twitter.
An alternative loanword, but less common than ミニブログ.
中国のマイクロブログは微博と呼ばれている。
China's microblog is called Weibo.
Referring to a single short message or update.
General term for a post or submission, works for any online platform.
その投稿はすぐに削除された。
That post was deleted immediately.
Loanword from English 'post', commonly used on Twitter/X.
彼のポストがバズった。
His post went viral.
Specifically a post on Twitter/X. Use only when the platform is clear.
Describing the action of writing and sharing a short message.
The standard verb for posting content online.
毎日ブログに投稿している。
I post on my blog every day.
Casual loanword, often used for social media.
さっき写真をポストしたよ。
I just posted a photo.
Literally 'to mutter', used for tweeting casually. Very informal.
In most conversations, it's more natural to name the specific service (Twitter, Instagram, etc.) rather than use a generic term like ミニブログ. The word ミニブログ is understood but sounds technical.
Directly translating 'microblog' as マイクロブログ can sound awkward. Use ミニブログ if you must use a generic term, but prefer the service name.
