The English adjective 'unrivalled' means having no equal; better than all others. In Japanese, this concept is expressed through various adjectives, nouns, and set phrases depending on the context—whether describing a person's skill, a product's quality, or an abstract quality. The most common and natural ways to convey this idea are introduced below, organized by usage.
