A Comprehensive Guide to Adjectives in Japanese

While learning the building blocks of Japanese is an important first step, it can be difficult to express yourself properly without the right adjectives. Japanese adjectives can help you describe yourself, tell stories, and get to know native speakers. They add depth and color to your sentences and can allow you to connect more deeply with whoever you’re speaking to. However, Japanese adjectives tend to be overlooked at first.

Many new speakers try to focus on learning the alphabet, memorizing kanji characters, and deciphering verb conjugation. But, if you really want to enhance your fluency, you need to dedicate some time to learning adjectives in Japanese. Over time, it will get easier, but to help you get started, here’s a comprehensive guide to learning adjectives in Japanese.

How Do Adjectives Work in Japanese?

There are two distinct types of adjectives in Japanese, い (i) adjectives and な (na) adjectives. Although different, both sets follow the same rule with only one exception that varies between the two. This can make learning the inner workings of Japanese adjectives much easier. To begin, let’s take a deeper look at how adjectives work in Japanese.

Does the Adjective Come Before the Noun in Japanese?

Japanese adjectives will always come before the noun, just like in English. This means you don’t have to worry about trying to memorize varying word order for sentences. Whether you want to say tall man (長者) or green car (グリーンカー), the order is the same.

How to List Adjectives in Japanese

When you want to use more than one Japanese adjective in a sentence, you can use a list format similar to English. You’ll need to add all of the adjectives in their conjugated form, except for the last one in the list. For example,

  • あのホテルは古くて、暗くて、汚かった。— The hotel was old, dark, and dirty.

In this example, we use old (古), dark (暗い), and dirty (淫ら) as three separate adjectives. You can see them expressed in the list above after being conjugated. To better understand how to do this, let’s learn more about how to conjugate Japanese adjectives.

Understanding Japanese Adjective Conjugation

Another key element of learning adjectives in Japanese is understanding the difference between い adjectives and な adjectives and how to conjugate them. While flashcards can help with rote memorization, one of the best ways to help solidify your understanding of Japanese adjectives is to download Tandem and match with a native speaker. This will give you real-world practice and a better understanding of how to incorporate adjectives naturally in your communication. Let’s explore both types below.

How to Conjugate い Adjectives in Japanese

い adjectives are considered “true” or “pure” adjectives and always end in the character い from the Japanese alphabet. However, not all adjectives that end in い are considered true adjectives. They can be used both to describe a noun or on their own. Some examples include:

  • 寒い — cold
  • 速い — fast
  • 甘い — sweet
  • 新しい — new
  • 面白い — interesting

Conjugating い adjectives in Japanese is what makes this form unique. Doing so will take the plain form of a word and change its tense. Luckily, if you know how to conjugate verbs in Japanese, conjugating adjectives is a breeze. With the exception of one rule, conjugating い adjectives all follow the same rule. Consider the table below on how to conjugate the Japanese adjective 速い (fast).

Plain Polite
Present (is fast) 速い 速いです
Present Negative (isn’t fast) 速くない 速くありません
Past (was fast) 速かった 速かったです
Past Negative (wasn’t fast) 速くなかった 速くありません でした

How to Conjugate the Only Irregular Japanese Adjective

In Japanese, there’s only one irregular adjective, which is いい (good). Although it’s in the Japanese script of hiragana, it’s often written in kanji as 良い. Therefore, it follows the same rules of conjugation as い adjectives. You can view this conjugation for 良い(good) in the table below.

Plain Polite
Present (is good) 良い 良いです
Present Negative (isn’t good) 良くない 良くありません
Past (was good) 良かった 良かったです
Past Negative (wasn’t good) 良くなかった 良くありませんでした

How to Conjugate な Adjectives in Japanese

な adjectives are considered “quasi” adjectives of “adjectival-nouns.” These types of adjectives can end in various characters, some of them even end in い. What sets these Japanese adjectives apart is the use of な. When used in a sentence, な will always appear between the adjective and the Japanese noun cases. If no noun precedes the Japanese adjective, the な can be dropped. Some examples include:

  • 元気 — healthy or lively
  • きれい — pretty or clean
  • 好き — favorite
  • 静か — quiet
  • 有名 — famous

Another thing to be aware of is that in some instances, い adjectives can change to な adjectives. However, this is usually only done in songs or poetry, so don’t worry about tackling that understanding just yet. For now, practice differentiating between the two and understanding conjugation.

To learn how to conjugate な adjectives in Japanese, let’s look at 元気 (healthy or lively) in various tenses below.

Plain Polite
Present (is lively) 元気だ 元気です
Present Negative (isn’t lively) 元気ではない 元気ではありません
Past (was lively) 元気だった 元気でした
Past Negative (wasn’t lively) 元気ではなかった 元気ではありませんでした
