1. Kanji Analysis: 梗 (KŌ / yō)
Meaning:
The kanji 梗 carries a range of meanings, from the literal to the abstract. Its core meanings are:
Stem, stalk, trunk (of a plant)
Main point, gist, outline
To obstruct, to block
(In modern internet slang) Meme, inside joke, running gag
Composition:
Radical: 木 (き, ki) - The "tree" or "wood" radical on the left, indicating a connection to plants.
Phonetic Component: 更 (KŌ) - This component provides the sound ("kō"). 更 itself means "to become late," "to renew," or "furthermore," and it contributes a sense of a mainstay or a firm point.
The combination creates an image of the firm, central, and supporting stalk of a plant, which is the source of its other meanings.

3. "梗" as a Tattoo: Meanings and Cautions
As a tattoo, "梗" is a highly nuanced and potentially high-risk choice. Its meaning can be interpreted in several ways, but the negative connotations are strong.
Potential Positive Meanings:
The Foundation of Your Story: Drawing from 梗概 (outline), it could symbolize that you are the author of your own life, focusing on the "main point" or the core narrative of your existence. It represents living with purpose and clarity.
Resilience and Strength: As the "stem" of a plant, it symbolizes being the central support of your own life—resilient, upright, and able to weather storms. It's a symbol of quiet strength from within.
A Nod to Internet Culture: For someone deeply embedded in online communities, it could be an insider's symbol for their love of memes and digital culture. However, this is a very niche and informal meaning.
Strong Cautions and Negative Connotations:
Overwhelmingly Negative Medical Association: The word 梗塞 (kōsoku) means "blockage" or "infarction," as in a heart attack or stroke. This is a very strong and frightening association. A tattoo could be misinterpreted as representing a serious health condition or, worse, inviting one.
Association with Stubbornness: The word 頑梗 (gankō) means "stubborn" and "obstinate." This is a generally negative personality trait that you likely do not want to be associated with.
The "Meme" Meaning is Not Serious: Using it to mean "meme" would be seen as trivial, confusing, and not worthy of a permanent tattoo in the eyes of most Japanese people.
Obscurity and Confusion: The positive meanings are abstract and not readily apparent. The negative meanings (blockage, stubbornness) are more direct and likely to be the first interpretation.
4. Final Verdict and Recommendation
"梗" is generally NOT RECOMMENDED for a tattoo.
The risk of severe misunderstanding—primarily the association with life-threatening medical conditions like heart attacks—is far too great. The positive interpretations are too intellectual and fragile to overcome the powerful negative and clinical connotations.
If you are drawn to the concepts of "core" or "resilience," here are far better and more positive alternatives:
For Core / Foundation, use 核 (kaku - core, nucleus) or 本 (hon - origin, root).
For Resilience / Strength, use 強 (tsuyoi - strong) or 耐 (taeru - to endure).
For Stem / Trunk (in a naturalistic sense), the kanji 幹 (miki - tree trunk) is a much stronger and more positive symbol, also meaning "main part" or "leader."
In summary:
While "梗" can conceptually represent the main point of one's life or inner strength, as a tattoo, it is an exceptionally poor choice. Its primary associations with disease and stubbornness make it a symbol that is more likely to cause concern or confusion than to convey a positive message. It is strongly advised to choose a different character with a clearer and more uplifting meaning.
