Meaning
The kanji 岳 (がく, たけ) primarily refers to a "peak," "high mountain," or "prominent mountain." Unlike the general term 山 (yama), which can mean any "mountain" or "hill," 岳 specifically denotes a grand, majestic mountain. It implies a significant, often named peak or a range of such peaks, highlighting their scale and importance beyond a mere hill. This is why you'll frequently see 岳 used in the names of famous Japanese mountains, such as 槍ヶ岳 (Yarigatake).
This kanji's origin lies in a semantic-phonetic compound. The upper component, 山 (yama), is clearly semantic, visually representing a mountain with its characteristic three peaks. The lower part, 丘 (oka), contributed phonetically in ancient Chinese and also semantically reinforces the idea of an elevated landform—a "hill" or "mound." Together, these elements paint a picture of a "mountain" built upon a "hill." This suggests something grander and more distinct than a mere hill. Visually, you can imagine the three peaks of 山 resting atop the lower structure, strongly emphasizing its prominent, mountainous nature.
The kanji 岳 has 8 strokes. While not assigned to a specific elementary school grade, it is a Jōyō Kanji, meaning it's designated for common use. Students typically encounter it at the secondary school level or higher, making it an essential character for JLPT N1 learners.

Memory Tip
To remember 岳, picture a "mountain" (山) proudly resting atop a "hill" (丘, representing the lower structure). The 山 radical clearly sits on this lower component. Imagine a humble hill aspiring to become a grand, prominent mountain, growing taller and more majestic until it earns a name. This visual helps reinforce that 岳 isn't just any mountain; it's a significant, high, and often renowned peak, standing out from its surroundings.
