樹海

• 読み: じゅかい
• ローマ字: jukai
• 漢字の分解: 樹 (ju/ki) — tree, plant; 海 (kai/umi) — sea, ocean
• 発音: /dʑɯ.ka.i/

意味

Sea of trees; an expanse of dense, primeval forest so vast it resembles an ocean when viewed from above.

A poetic compound noun most famously associated with the Aokigahara forest (青木ヶ原樹海) at the base of Mount Fuji, known for its extremely dense woodland and volcanic rock that reportedly affects compass readings. The word captures the overwhelming, ocean-like scale of dense woodland, and is also used more broadly for any vast, unbroken forested landscape.

例文

1. 富士山を背景に広がる青木ヶ原樹海は、息をのむほどの絶景だ。
2. 樹海の内部では木々が密集しているため、方向感覚を失いやすい。
3. 上空から眺めると、その樹海がいかに広大であるかがよく分かる。
