Japanese has only two verb tenses:

The Present
The Past

There is no future tense or perfect tense.

So, you might think it will be really simple to learn verb conjugations.

But actually there are many verb forms and how to conjugate verbs are quite different from English.

In English, when you form a negative sentence, you use "NOT", but in Japanese, we need to conjugate verbs to make a negative sentence.

Take Miru (to watch) as an example :

There are a lot more conjugation patterns and learning conjugation will be the second biggest challenge you will face after the Japanese alphabets.

But the good news is that Japanese verb conjugation is independent of the person, number, and gender.

This means whether the subject is the first person singular or third person plural, the verb conjugation is always the same.

So Miru can mean, "I watch", "you watch", "he/she/it watches", "we watch", "they watch".

Also, there are only two irregular verbs which make learning verb conjugations a lot easier!
