Negative Past Tense for Adjectives
Learn how to express that something was NOT a certain way in Japanese! This lesson focuses specifically on forming the negative past tense of adjectives to describe how things weren't in the past.
Negative past tense of adjectives is one of the more difficult concepts for beginners to master. Take your time with this lesson and practice the patterns thoroughly.
๐ฏ Learning Objectives
- โข Master the negative past tense patterns for both ใ-adjectives and ใช-adjectives
- โข Understand how to say something "was not" a certain way in Japanese
- โข Practice using negative past adjectives in sentences
- โข Learn common time expressions used with past tense
- โข Avoid common mistakes when forming negative past adjectives
The Two Types of Japanese Adjectives
Before learning the negative past tense, it's important to understand that Japanese has two main types of adjectives that conjugate differently:
1. ใ-adjectives
These adjectives always end with the hiragana character ใ and conjugate by changing this ending.
- โข ใใใใ (delicious)
- โข ใใใ (expensive)
- โข ใใใใใ (new)
- โข ใใใใใ (interesting)
2. ใช-adjectives
These adjectives don't end with ใ (with a few exceptions) and conjugate by using forms of ใงใ/ใใ.
- โข ใใใ (beautiful/clean)
- โข ใใใ (quiet)
- โข ในใใ (convenient)
- โข ใใใ (healthy/energetic)
Important: Each type of adjective follows different rules for making the negative past tense. We'll focus on both types in this lesson.

Negative Past Tense of ใ-Adjectives
To say something "was not [adjective]," we need to use the negative past form. For ใ-adjectives, we first change to the negative form (ใใชใ), then make it past tense.
Pattern for Negative Past ใ-Adjectives:
- Step 1: Remove the final ใ
ใใใใ โ ใใใ - Step 2: Add ใใชใ (to make it negative)
ใใใ + ใใชใ โ ใใใใใชใ - Step 3: Change ใชใ to ใชใใฃใ (past negative)
ใใใใใชใ โ ใใใใใชใใฃใ - Step 4: For polite speech, add ใงใ
ใใใใใชใใฃใ โ ใใใใใชใใฃใใงใ
ใใ (good): ใใ conjugates in a different way than other ใ-adjectives: ใใ โ ใใใชใ โ ใใใชใใฃใใงใ.
More Examples:
- ใใใ โ ใใใใชใ โ ใใใใชใใฃใใงใ
was not expensive
- ใใใใ โ ใใใใใชใ โ ใใใใใชใใฃใใงใ
was not easy/kind
- ใใใ โ ใใใใชใ โ ใใใใชใใฃใใงใ
was not cold
Using in Sentences:
- ใใฎใใใใฏใใใใใใชใใฃใใงใใ
That movie was not interesting.
- ใใฎใใฏใใใใชใใฃใใงใใ
Yesterday was not cold.
- ใใฎใปใใฏใใใใใใชใใฃใใงใใ
This book was not difficult.
Negative Past Tense of ใช-Adjectives
For ใช-adjectives, the negative past form follows a different pattern. Instead of changing the adjective itself, we use ใงใฏใใใพใใใงใใ after the adjective.
Pattern for Negative Past ใช-Adjectives:
- Step 1: Take the basic form of the ใช-adjective
Example: ใใใ (beautiful/clean) - Step 2: Add ใงใฏใใใพใใใงใใ
ใใใ + ใงใฏใใใพใใใงใใ โ ใใใใงใฏใใใพใใใงใใ
Note: Some speakers use ใใใใใพใใใงใใ instead of ใงใฏใใใพใใใงใใ. Both are correct, but ใงใฏใใใพใใใงใใ is more formal and appropriate for polite situations.
For example: ใใใใใใใใพใใใงใใ is the more casual version of ใใใใงใฏใใใพใใใงใใ.
Formal vs. Casual: ใงใฏ vs. ใใ
Formal (ใงใฏ):
- โข ใใใใงใฏใใใพใใใงใใ
- โข ในใใใงใฏใใใพใใใงใใ
- โข Use in: business settings, with teachers, with strangers, in writing
Casual (ใใ):
- โข ใใใใใใใใพใใใงใใ
- โข ในใใใใใใใพใใใงใใ
- โข Use with: friends, family, casual conversations
In this course, we'll focus on the formal ใงใฏ form, but it's important to recognize the ใใ form when you hear it in everyday conversations, TV shows, or anime.
More Examples:
- ใใใ โ ใใใใงใฏใใใพใใใงใใ
was not quiet
- ในใใ โ ในใใใงใฏใใใพใใใงใใ
was not convenient
- ใซใใใ โ ใซใใใใงใฏใใใพใใใงใใ
was not lively
Using in Sentences:
- ใใฎใฌในใใฉใณใฏใใใใงใฏใใใพใใใงใใใ
That restaurant was not clean.
- ใใฎใใฏใใใใงใฏใใใพใใใงใใใ
I was not feeling well yesterday.
- ใใฎใใผใใฃใผใฏใซใใใใงใฏใใใพใใใงใใใ
That party was not lively.
Cultural Note: Understanding when to use formal (ใงใฏใใใพใใใงใใ) versus casual (ใใใใใพใใใงใใ) language is an important aspect of Japanese communication. The formal version is typically used in business settings, with teachers, superiors, or in formal writing. The casual version is used among friends, family members, and in relaxed settings.
Time Expressions for Past Tense
When describing past conditions with negative adjectives, it's often helpful to include time expressions to clarify when something wasn't a certain way.
