outdoor gambling
Archaic term for gambling conducted outdoors, often in a makeshift or illicit setting. Not used in modern Japanese; encountered only in historical or literary contexts.
江戸時代には、野博打が取り締まりの対象だった。
In the Edo period, outdoor gambling was subject to crackdowns.
Compound of 野 (no, 'field, outdoors') and 博打 (bakuchi, 'gambling'). The reading のばくち is a straightforward combination; the exact historical origin is uncertain.
