Japanese Verb Review (Positive)
Before we begin with the negative past tense, let’s review some basic Japanese verbs in their positive form.
Japanese | Romaji | English |
ある(non-living things) | aru | to be (present) |
いる(living things) | iru | to be (present) |
食べる | taberu | to eat |
飲む | nomu | to drink |
寝る | neru | to sleep |
Now, let’s use the above verbs to create sentences in the positive form!
テーブルがある。
Teeburu ga aru.
There is a table.
今夜私は12時間寝る。
Konya watashi wa juu-ni jikan neru.
I will sleep 12 hours tonight.
Japanese Verb Review (Negative)
Now that we’ve reviewed some verbs in their positive form, let’s review them in their negative form.
Remember, conjugating the verb into its negative form depends on the type of verb.
If it’s a u–verb, you change the last hiragana character into the corresponding character that ends in an “a” sound. After that, you add ない (nai) to the end (e.g. 話す ➝ 話さない, 聞く ➝ 聞かない). If the u–verb ends with the character う (u), you change it into a わ (wa) (NOT あ [a]) (e.g. 会う➝会わない, 歌う ➝ 歌わない).
If it’s a ru–verb, you simply change the last character る (ru) into ない。
Irregular verbs like する (suru) and 来る (kuru) abide by their own rules; and ある (aru) simply becomes ない (see the table below).
Japanese | Romaji | English |
飲む ➝ 飲まない | nomu ➝ nomanai | to drink ➝ to NOT drink |
使う ➝ 使わない | tsukau ➝ tsukawanai | to use ➝ to NOT use |
食べる ➝ 食べない | taberu ➝ tabenai | to eat ➝ to NOT eat |
ある ➝ ない(non-living things) | aru ➝ nai | to be (present) ➝ to NOT be (present) |
いる ➝ いない(living things) | iru ➝ inai | to be (present) ➝ to NOT be (present) |
する ➝ しない | suru ➝ shinai | to do ➝ to NOT do |
来る ➝ 来ない | kuru ➝ konai | to come ➝ to NOT come |
Now that we’ve reviewed how to conjugate verbs into their negative form, let’s create a few sentences!
明日私はバスケットボールをしない。
Ashita watashi wa basukettobooru wo shinai.
I won’t play basketball tomorrow.
彼女はお肉を食べない。

Japanese Past Tense Review (Positive)

Now that we’ve reviewed both the positive and negative forms of some Japanese verbs, let’s take some time to review the past tense. Remember, we are only focusing on the casual form.
Japanese | Romaji | English |

使う ➝ 使った | tsukau ➝ tsukatta | to use ➝ used |
食べる ➝ 食べた | taberu ➝ tabeta | to eat ➝ ate |
ある ➝ あった(non-living things) | aru ➝ atta | to be ➝ was |
いる ➝ いた(living things) | iru ➝ ita | to be ➝ was |
する ➝ した | suru ➝ shita | to do ➝ did |
来る ➝ 来た | kuru ➝ kita | to come ➝ came |
Now that we’ve reviewed some verbs in the past tense, let’s create some sentences about past states of being!

Japanese Negative Past Tense Verbs
The negative past tense expresses that someone or something was NOT present, or that they did NOT do something.
The negative past tense for あった (atta) becomes なかった (nakatta), and いた becomes いなかった。
– | Japanese | Romaji | English |
NON-LIVING THINGS | あった ➝ なかった | atta ➝ nakatta | was (present) ➝ was NOT (present) |
LIVING THINGS | いた ➝ いなかった | ita ➝ inakatta | was (present) ➝ was NOT (present) |
Example sentences:
今年桜はなかった。
Kotoshi sakura wa nakatta.
This year there were no cherry blossoms.
マネジャーはお店にいなかった。
Manejaa wa o-mise ni inakatta.
The manager was not at the shop.
Conjugating the rest of the verbs into the negative past tense is simple! You just conjugate them into their negative form (see earlier table), remove the ない (nai) at the end, and replace it with なかった (nakatta)!
Japanese | Romaji | English |
飲ま | noma | to not drink ➝ did not drink |
使わ | tsukawa | to not use ➝ did not use |
食べ | tabe | to not eat ➝ did not eat |
し | shi | to not do ➝ did not do |
来 | ko | to not come ➝ did not come |

In Summary
