Translation guide
In Japanese, the concept of 'sergeant' is expressed differently depending on the context: military, police, or historical. The most common modern terms are 軍曹 (gunsō) for military sergeants and 巡査部長 (junsa buchō) for police sergeants. In historical or samurai contexts, 侍長 (samurai chō) or 組頭 (kumigashira) may be used.

Literally 'police sergeant', but this is not a standard Japanese term. It might be used in translations or when referring to foreign police forces with military-style ranks. Generally, use 巡査部長 for Japanese police.

In Japan, police ranks are separate from military ranks. Using 軍曹 to refer to a Japanese police officer would be incorrect. Always use 巡査部長 for a Japanese police sergeant.
When translating 'sergeant', first determine whether it's a military or police context, and whether it's modern or historical. The default modern military term is 軍曹, and the default modern police term is 巡査部長.
