The kanji 岡 primarily represents a "hill" or a "mount" – a slightly elevated area of land, not as steep as a mountain. It implies a place that is higher than the surrounding area, but not necessarily a large or imposing structure. It can also refer to a "ridge" or a "knoll."

The kanji 岡 is a phono-semantic compound. ⚫︎The left side is the radical "⻖" which is a variation of "阜" (fù), meaning "mound" or "hill." ⚫︎The right side "｜" is from the character "丨" (gǔn), which represents a vertical stroke. It is related to a small vertical ridge. Therefore, 岡 combines the meaning of "mound" with a visual hint of a small or narrow elevated area, creating the meaning of "hill".
