Translation guide
The concept of worthlessness can be expressed in Japanese through nouns, adjectives, and idiomatic phrases. The most common and versatile word is 無価値 (mukachi), but other options like 無益 (mueki) or 役立たず (yakudatazu) are used depending on whether you're talking about objects, actions, or people. This guide covers the main ways to convey worthlessness, from formal to casual.

無価値 (mukachi) is a formal, literary term often used in written Japanese or serious discussions. 価値がない (kachi ga nai) is the everyday equivalent and more natural in conversation.
