This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
岒 combines 山 (mountain) with 今, but the historical origin and original meaning are uncertain. It may have been a place name or a rare character.
The left side is a mountain 山, and the right side is 今 (now). Picture a mountain that suddenly appeared now, but its meaning remains a mystery.
For ケン, imagine a mountain named Ken that appears now: Ken -> ケン, and the mountain 山 stands beside 今.
