noun
Climacium japonicum (a species of moss)
A species of moss native to Japan, often found in mountainous areas. The name is typically written in katakana.
コウヤノマンネンゴケは山地の湿った場所に生える。
Climacium japonicum grows in damp places in mountainous areas.
The name is a compound of 高野 (Kōya, referring to Mount Kōya), の (possessive particle), 万年 (mannen, 'ten thousand years' or 'eternal'), and 蘚 (koke, 'moss'). The exact origin of the name is uncertain, but it likely refers to the moss's association with the sacred Mount Kōya and its long-lasting nature.
