Overview

Cleaner line breaks for Japanese captions on YouTube—powered by Budoux.

Better Japanese Captions reflows Japanese subtitle lines on YouTube so they break at more natural places—easier to read at a glance. How it works: • Runs only on youtube.com pages (desktop and mobile domains declared in the manifest). • Uses Budoux-style segmentation bundled inside the extension—no caption text is sent to a developer-operated server. • Includes an on-player toggle to restore YouTube’s original caption layout when you want to compare. Privacy: • No accounts, no analytics SDKs, no remote caption uploads by this extension. • See the Privacy Policy linked from the listing for details. YouTube の日本語字幕が、読みやすい位置で改行されるようにレイアウトを調整します。処理はすべてブラウザ内で行われます。 • 対象サイトはマニフェストで指定した YouTube(youtube.com/www/m のみ)。 • Budoux に相当するモデルを同梱しローカルで分割。開発者運用サーバーへの字幕送信はありません。 • プレーヤー横のトグルで、本来の字幕レイアウトに戻して比較できます。 • アカウント不要・アプリ内解析・字幕データの開発者側収集なし。
