noun, noun or participle which takes 'suru'
looking afar; taking an extensive view
Archaic literary noun or suru-verb for gazing into the distance or surveying a broad scene. Not used in modern everyday Japanese.
古い詩文では「瞻望」が遠くを見渡す意味で使われる。
In old poetry and prose, 瞻望 is used to mean looking out over a distance.
Archaic kanji spelling; the word itself is rare and literary.
展望 is the modern common word for 'view' or 'outlook', both literal and figurative, while 瞻望 is an archaic literary term for physically gazing afar.
The exact derivation is uncertain; the kanji 瞻 (look up, gaze) and 望 (hope, view) combine to suggest looking into the distance, but the word is not in common use.
