noun
everywhere; all over; at every turn
Describes something occurring or being present in many places, often with a nuance of 'wherever you look'. Slightly formal; common in written Japanese and news reports.
この公園には随所にベンチが設置されている。
Benches are placed everywhere in this park.
彼の小説には随所にユーモアが見られる。
Humor can be found throughout his novel.
Compound of 随 (wherever, following) and 所 (place). The meaning 'every place' follows naturally from the kanji components.
