English adjectives are more similar to nouns than to verbs, and they require the copula be to become predicators. On the other hand, Japanese adjectives are more similar to verbs, and they don't need a copula. They have inflection like verbs.

All Japanese adjectives end with the hiragana (i) "i" if they are in the nonpast form. An adjective consists of a stem and a suffix as verbs do, and the stem never changes while suffixes can change. The final /i/ in the nonpast form of an adjective is the suffix, and the rest is the stem. Please note that the suffix for the nonpast form of verbs is /u/, and that of adjectives is /i/.

 Sample Adjectives:

 

Adjective	Stem	Suffix	Meaning
	yo	i	is good
	atu		is hot
	uresi		is glad
	oishi		is tasty

Since adjectives always end with the hiragana (i), the stem of an adjective always ends with a vowel. Japanese adjectives are similar to verbs, so you can consider them to be a combination of the copula be and an adjective in English.
