折に【おりに】

折に (おりに) is a formal expression meaning "on the occasion of", "when", or "at the time of". It is used to refer to a particular occasion or opportunity, often one that is special, noteworthy, or not an everyday occurrence. It carries a more literary and refined tone compared to casual alternatives like とき (when).

Basic Usage

折に attaches to verbs (plain form) or nouns + の to indicate the occasion on which something happens.

With Nouns

When used with a noun, it takes the form Noun + の + 折に.

Variants: 折には and 折

The particle に can be replaced with には to add emphasis, or omitted entirely when 折 modifies a noun directly (e.g. そのおり折 – "on that occasion"). The form 折には is used when the speaker wants to set up a conditional or hypothetical occasion.

Nuance and Register

折に is distinctly formal and polite. It is commonly found in business correspondence, formal invitations, speeches, and polite conversation. It implies that the occasion is somewhat significant or opportune – not a routine or trivial moment. Because of its formal register, it pairs naturally with polite and honorific expressions.

Compare:

• あった会ったとき時にはなした話した – casual: "I talked about it when we met."
• おあいしたお会いしたおり折におはなしいたしましたお話しいたしました – formal: "I discussed it on the occasion of our meeting."

Common Patterns

折に is used with phrases of request or invitation, such as:

• 〜～おり折にはよろしくおねがいいたしますお願いいたします – "When the time comes, I look forward to your help."
• 〜～おり折にはおしらせお知らせください – "Please let me know when the occasion arises."
