The English word 'animal' can refer to non-human creatures, living organisms in the kingdom Animalia, or be used metaphorically to describe a person with brutish or wild behavior. This guide covers the most common and natural Japanese equivalents for these meanings.

Literally 'living thing', broader than 動物, can include plants and microorganisms, but often used for animals in a more emotional or philosophical context.

While English uses 'animal' to describe a brutish person, direct translation to 動物 is not natural in Japanese. Use けだもの or 畜生 instead, but be aware these are strong insults.
