OP

• 読み: オーピー
• ローマ字: oopii
• 漢字の分解: Abbreviation of English 'opening.' Written in roman letters (OP) in Japanese contexts.
• 発音: /o.o.pi.i/

意味

Opening theme; the song and animation sequence that plays at the start of each anime episode.

OP (pronounced オーピー) is one of the most fundamental terms in anime fandom. The opening sequence — combining animation, music, and often hidden foreshadowing — is a beloved art form in itself. Fans analyze OP visuals frame by frame, debate which anime has the best OP, and many discover new music through OPs. A great OP sets the tone for the entire series, and some become more famous than the anime itself.

例文

3. OPだけでそのクール覇権取れるレベルの曲じゃん。

正しい言い方

• 今期アニメで一番OPがいいのどれ？ (Which anime this season has the best OP?)
• OP飛ばさないで毎回ちゃんと見るタイプ。 (I'm the type who watches the OP every episode without skipping.)

避ける言い方

• ドラマや映画のテーマ曲に「OP」は普通使わない — OP is specific to anime/game episode format, not films or dramas

よくある間違い

• Confusing OP with 主題歌 — OP is the per-episode opening sequence, while 主題歌 can refer to a work's overall theme song
• Using OP for One Piece in a music discussion — context matters, as OP also commonly abbreviates ワンピース
