Past Tense in Japanese
Mastering Japanese Past Tense
If youโre learning Japanese, understanding how to express actions in the past is essential for communication. Japanese verbs are logically structured, and once you master their conjugations, youโll be ready to share stories, describe events, and more.
In this post, weโll focus on the positive past tense and the negative past tense, with step-by-step explanations for verbs ending in different sounds (like -ku, -ru, -mu, and more). By the end, youโll feel confident using these forms in your Japanese conversations.
The Basics of Japanese Past Tense
Japanese verbs donโt conjugate based on the subject, so thereโs no distinction between โI ateโ and โshe ate.โ The conjugation only reflects tense (past, present, etc.) and polarity (positive or negative).
The two forms weโll focus on are:
- Positive Past Tense โ For actions that happened.
- Negative Past Tense โ For actions that didnโt happen.
1. Positive Past Tense: ้ฃในใ (tabeta) โ “ate”
The positive past tense is based on the ใ-form of the verb. To create it, we modify the ending of the verb according to its type.
Group 1 (U-verbs)
For U-verbs, the conjugation depends on the final -u sound. Each sound (-ku, -ru, -mu, etc.) follows a specific rule:
Ending Change Example -ใ (u) Replace ใ with ใฃใ ไผใ (au, “to meet”) โ ไผใฃใ (atta, “met”) -ใค (tsu) Replace ใค with ใฃใ ๅพ ใค (matsu, “to wait”) โ ๅพ ใฃใ (matta, “waited”) -ใ (ru) Replace ใ with ใฃใ ่ตฐใ (hashiru, “to run”) โ ่ตฐใฃใ (hashitta, “ran”) -ใ (mu) Replace ใ with ใใ ้ฃฒใ (nomu, “to drink”) โ ้ฃฒใใ (nonda, “drank”) -ใถ (bu) Replace ใถ with ใใ ้ใถ (asobu, “to play”) โ ้ใใ (asonda, “played”) -ใฌ (nu) Replace ใฌ with ใใ ๆญปใฌ (shinu, “to die”) โ ๆญปใใ (shinda, “died”) -ใ (ku) Replace ใ with ใใ ๆธใ (kaku, “to write”) โ ๆธใใ (kaita, “wrote”) -ใ (gu) Replace ใ with ใใ ๆณณใ (oyogu, “to swim”) โ ๆณณใใ (oyoida, “swam”) -ใ (su) Replace ใ with ใใ ่ฉฑใ (hanasu, “to speak”) โ ่ฉฑใใ (hanashita, “spoke”) Examples:
- ๅพ ใค โ ๅพ ใฃใ (matsu โ matta): waited
- ๆธใ โ ๆธใใ (kaku โ kaita): wrote
- ๆณณใ โ ๆณณใใ (oyogu โ oyoida): swam
- ้ใถ โ ้ใใ (asobu โ asonda): played
Group 2 (RU-verbs)
For RU-verbs, simply drop the ใ and add ใ.
Examples:
- ้ฃในใ (taberu, “to eat”) โ ้ฃในใ (tabeta, “ate”)
- ่ฆใ (miru, “to see”) โ ่ฆใ (mita, “saw”)
Irregular Verbs
There are two irregular verbs in Japanese with unique conjugations:
- ใใ (suru, “to do”) โ ใใ (shita, “did”)
- ๆฅใ (kuru, “to come”) โ ๆฅใ (kita, “came”)
2. Negative Past Tense: ้ฃในใชใใฃใ (tabenakatta) โ “did not eat”
To express that something did not happen, we use the negative past tense, which builds off the ใชใ-form of the verb.
How to Form the Negative Past Tense
- Convert the verb to its ใชใ-form (present negative).
- Replace ใชใ with ใชใใฃใ.
Group 1 (U-verbs)
The process for creating the ใชใ-form depends on the ending of the verb:
- Change the final -u to its corresponding -a sound, then add ใชใ.
Example: ้ฃฒใ (nomu, “to drink”) โ ้ฃฒใพใชใ (nomanai, “do not drink”). - Finally, replace ใชใ with ใชใใฃใ for the past tense: ้ฃฒใพใชใใฃใ (nomanakatta, “did not drink”).
Examples:
- ๆธใ (kaku, “to write”) โ ๆธใใชใ โ ๆธใใชใใฃใ (kakanakatta, “did not write”)
- ๆณณใ (oyogu, “to swim”) โ ๆณณใใชใ โ ๆณณใใชใใฃใ (oyoganakatta, “did not swim”)
- ่ฉฑใ (hanasu, “to speak”) โ ่ฉฑใใชใ โ ่ฉฑใใชใใฃใ (hanasanakatta, “did not speak”)
Group 2 (RU-verbs)
For RU-verbs, simply drop ใ and add ใชใ, then conjugate to ใชใใฃใ.
Examples:
- ้ฃในใ โ ้ฃในใชใ โ ้ฃในใชใใฃใ (taberu โ tabenai โ tabenakatta): did not eat
- ่ฆใ โ ่ฆใชใ โ ่ฆใชใใฃใ (miru โ minai โ minakatta): did not see
Irregular Verbs
The two irregular verbs follow special patterns:
- ใใ โ ใใชใ โ ใใชใใฃใ (suru โ shinai โ shinakatta): did not do
- ๆฅใ โ ๆฅใชใ โ ๆฅใชใใฃใ (kuru โ konai โ konakatta): did not come

Tips for Mastery
- Group Drill Practice: Practice conjugating verbs in groups based on their endings (-ku, -su, -mu, etc.) to build muscle memory.
- Daily Use: Write about your day using past tense. Did you eat? Watch a movie? Think about what you didnโt do as well.
- Flashcards: Use flashcards for common verbs in their dictionary, positive past, and negative past forms.
Understanding Japanese past tense empowers you to share your experiences and engage in deeper conversations. With regular practice, youโll master these forms in no time. ใใใฐใฃใฆ (Ganbatte, “Good luck!”)!
