Kanji for “remembrance”

Keeping a person or an event present after they are gone, rather than memory as a mental faculty.

追憶 tsuioku

Closest natural translation · misunderstanding risk Low

Reading: tsuioku — Common compound reading
About the reading: A standard noun, more at home in writing and in song titles than in conversation.
Literal meaning: Recollection; looking back
What it suggests: Memory as the act of looking back at something that is over. Warm and a little wistful — it carries the distance between now and then. A dictionary will usually offer 記憶 (kioku) instead, but that is memory as a faculty, the word for what a computer holds and what a witness gives; it is far flatter than most people intend.
When to use it: For remembrance as reflection on what has passed.
On its own: Natural as a complete noun, though it belongs to written and lyrical registers.
In compounds: Natural in 追憶の日々 (days of recollection).
As a tattoo: Quiet and literate. It reads as the act of remembering rather than as an instruction to remember.

忘れない wasurenai

Related meaning, not a literal translation · misunderstanding risk Low

Reading: wasurenai — Mixed kanji and kana; plain negative verb
About the reading: The れない is grammar, not ornament. Remove it and the phrase stops being Japanese.
Literal meaning: I will not forget
What it suggests: A promise rather than a noun. This is what Japanese actually writes when it means this — it stands on memorial markers for the 2011 disaster — and it carries the weight of a vow made to someone in particular.
When to use it: For a promise not to forget a person or an event.
On its own: Very natural and plain-spoken. The casual register reads as sincerity here rather than carelessness.
In compounds: Not a compound; it is a complete sentence.
As a tattoo: The most direct of the three and the least decorative. Three of its four characters are kana, so it looks like handwriting rather than an emblem — which is the point.

面影 omokage

Symbolic choice, not a literal translation · misunderstanding risk Low

Reading: omokage — Common standalone reading; kun-yomi
About the reading: Read as one word; neither character is pronounced on its own here.
Literal meaning: The lingering image of a face
What it suggests: Not memory in general — the trace of one person that stays with you, and that you catch somewhere else: a gesture in their child, a way of standing seen across a room. Specific, and quietly devastating.
When to use it: For the presence of one particular person that has not left.
On its own: Natural, literary, and understood immediately.
In compounds: Natural in 面影を残す (to leave traces of someone).
As a tattoo: The most beautiful of the three and the most specific. It says a person rather than a concept, which is usually what a memorial tattoo is for.

Before it is permanent: have a fluent Japanese speaker check the exact characters in the final stencil, not in an email. Fonts substitute look-alike characters, and a shop that cannot read Japanese cannot catch it.
