Origin

This character is a Japanese invention (called a kokuji) that combines the idea of a mountain with a crucial point. The left side shows the mountain radical, which depicts a peaked landform. The right side contains a small marker or accent that represents the passing point — the specific spot where a mountain road crosses over a ridge. Together, the character visually suggests the peak or pass of a mountain, capturing both the geography and the sense of reaching a critical high point before descending.
