place in Taiwan
崁 is a rare kanji used primarily in a Taiwanese place name. Its standalone meaning is tied to that specific location and does not have a clear general conceptual center beyond its geographic use.
崁 combines 山 (mountain) with 坎 (pit, hole), likely to describe a mountainous hollow or a specific topographical feature. The exact historical development is uncertain.
A mountain 山 with a pit 坎 at its base: picture a distinctive hollow in a Taiwanese mountain that gave the place its name.
For カン, imagine a can sitting in the mountain hollow: can -> カン, and the can marks the place in Taiwan.
